Class 9 History Civics Worksheet-10
INTRODUCTION:
The Vedic period or Vedic age is from 1500-500 BCE. The designation “Vedic Period” is
a modern construct, which relies on evidence of an Indo-Aryan migration, which, as noted,
is not universally accepted. It is a period of late Bronze Age and the early IRON AGE of
the history of India when the Vedas were composed in the northern Indian subcontinent.
The Vedas contain details of life during this period that has been interpreted to be historical
and constitute the primary source for understanding the period. The Vedic literature
consists of three successive classes of literary creation.
THE THREE CLASSES ARE
THE VEDA
THE BRAHMANAS
THE ARANYAKAS & THE UPANISHADS
THE VEDA:
A collection of hymns, prayers, charms, and sacrificial formulae is known as VEDA. They
are commonly referred to as “scripture”, p0.which is accurate in that they can be defined
as holy writing concerning the nature of the Divine. The Vedas were orally transmitted
since their composition in the Vedic period from father to son or from teacher (guru) to
student (shishya), believed to be initiated by the Vedic rishis who heard the primordial
sounds. Only this tradition, embodied by a living teacher, can teach the correct
pronunciation of the sounds and explain hidden meanings, in a way the "dead and entombed
manuscript" cannot do. It is further divided into four parts.
1) RIG VEDA:
They are the oldest of the scared books of Hinduism composed in an ancient form of
Sanskrit in about 1500 BCE. The text is layered consisting of the Samhita, Brahmanas,
Aranyakas and Upanishads. The Rig-Veda hymns were composed and preserved by oral
tradition. They were memorized and verbally transmitted across generations for many
centuries.
2) SAM VEDA:
The Sam Veda is shortest of all the four Vedas. It is closely connected with the Rig-Veda.
It is the Veda of melodies and chants. It consists of 1549 verses. These are probably the
world’s oldest surviving melodies.
3) YAJURVEDA:
It is the Veda mainly of prose mantras for worship rituals. The exact century of
YAJURVEDAS composition is unknown and is estimated by scholars to be around 1200-
1000 BCE. The earliest and most ancient layer of Yajurveda includes about 1,875 verses
that are distinct yet borrow and build upon the foundation of verses in Rig-Veda.
4) ATHARVAVEDA:
The text is the fourth VEDA, but has been a late addition to the Vedic scriptures. It is a
collection of spills and charms. The Atharvaveda is composed in Vedic Sanskrit, and it is
a collection of 730 hymns with about 6,000 mantras, divided into 20 books. About a sixth
of the Atharvaveda texts adapts verses from the Rig-Veda, and except for Books 15 and
16, the text is in poem form deploying a diversity of Vedic matter.
2) BRAHMANAS:
These are prose text which contains details about the meaning of Vedic hymns, their
application and their stories. The Brahmans are associated with SHAKAS &VEDIC
SCHOOL. Each Veda has one or more Brahmanas of its own. . They are a secondary layer
or classification of Sanskrit texts embedded within each Veda, often incorporating myths
and legends to explain and instruct Brahmins on the performance of Vedic rituals. The
Brâhmanas are thus our oldest sources from which a comprehensive view of the sacrificial
ceremonial can be obtained. They also throw a great deal of light on the earliest
metaphysical and linguistic speculations of the Hindus.
3) THE ARANYAKAS & THE UPNISHADS:
a) THE ARANYAKAS:
They explain the philosophy behind the ritual of sacrifice
of ancient HINDU text i.e. VEDA. It is derived from the
word Araṇya which means wilderness. The structure of
the Aranyakas is as little homogenous as their contents.
The concluding portions of Brahmans are known as
the ARANYAKAS. Many ARANYAKAS are
MANTRAS, INDENTIFICATION, DISCUSSIONS,
MYTHS and SYMBOLIC INTEPRETATIONS. The Brahmans
are mainly concerned with the proper performance of the rituals.
They are also known as the forest books.
THE UPANISHADS
They are widely known as the central idea of the spiritual core of Hinduism. They are
considered to be the end of the Vedas. Upanishads has also been interpreted as the meaning
of secret teaching or revealing of truth. The literal meaning is to sit down closely as one
would listen attentively to the instructions of the GURU or a TEACHER. Among the most
important literature in the history of Indian religions and culture, the Upanishads played an
important role in the development of spiritual ideas in ancient India, marking a transition
from Vedic ritualism to new ideas and institutions.
EPICS
IMPORTANCE OF EPICS
It gives information about social, cultural and political people of that age
It has two great epics, that is long descriptive verses tell the stories of great heroes were
written then. These two epic were the Ramayana and the Mahabharata.
Both epic is considered sacred in Hinduism. The Ramayana basic story is on the mouth of
every Indian as its story of Ram Chandra and Sita and of their fight against Ravana the
devil, king of Lanka. The original epic was written by Valmiki in Sanskrit. Ramayana
teaches the philosophy of life. It reveals the importance of family.
ANSWER THE FOLLOWING QUESTIONS
1)Name the four Vedas and describe any two briefly?
2)Name the two great epics of the epic age?
3)How were Brahmanas associated to Vedic school?
4)Write a short note about Vedic age.
5)How are Aranyakas connected to Brahmanas?
6)Give the meaning of Veda.

The Oceans
HYDROSPHERE - THE OCEANS
The Earth is the only planet in the solar system to have water in abundance. So, the
Earth is also called a “Water Planet” or “Blue Planet”. Water makes life possible on
the Earth. Hydrosphere is the water share, all the waters (liquid or solid) of the
surface of the Earth collectively, including soil and groundwater.
It consists of liquid water in sedimentary rocks, rivers, lakes and oceans as well as
ice in the sea and continental ice sheets. Water also occurs in the atmosphere as
gaseous vapours, liquid droplets and ice crystals.
Hydrosphere is one of the realms of the Earth. Atmosphere, Hydrosphere,
Lithosphere and Biosphere, are interlinked by hydrological cycle. The term
“Hydrosphere” is generally used in comparison and contrast with the Lithosphere
and Atmosphere.
Distribution of Land and Water
About 225 million years ago, all the continents were joined together forming a super
continent known as Pangaea. Pangaea was covered by a vast ocean called
Panthalassa. Later on, the continents started drifting apart.
The North and South America drifted westward and Atlantic Ocean was formed.
The Indian peninsula and Australia drifted eastward giving rise to the Indian Ocean
and the present form of continents and oceans came into existence.
Land and water are not uniformly distributed over the Earth. About 71% of the Earth
surface is occupied by seas and oceans where as land covers 29% of the total Earth's
surface.
If we examine the distribution of land and water on the globe, we notice a number of
outstanding features:
There is an antipodal balance of land and water on directly opposite sides of the
globe. It means that the continents and oceans are roughly arranged in such a way
that land on one side of the globe is balanced by water on the opposite side of the
globe. For example, the North Polar Arctic Ocean is opposite to the Antarctica
continent.
The continents have roughly triangular shape with their wide bases in the north.
They are narrowest in the southern hemisphere. Australia and Antarctica are
exceptions.
The oceans are also roughly triangular in shape having their bases in the south with
their vertex in the north.
Oceans are more extensive in the southern hemisphere than in the northern
hemisphere. In the northern hemisphere, the areas of land and water are nearly equal,
while in the southern hemisphere, there is nearly fifteen times as much water as
land.
The gap between Antarctica and the southern parts of the continents from the
southern ocean, which keeps Antarctica isolated.
Antarctica has three prominent protruding areas - one extending towards South
America, second towards Southern Africa and the third towards Australia.
Oceanography is the science and study of oceanic phenomena. The five important
oceans in order of their size are the Pacific, Atlantic, Indian, Southern and the Arctic
Ocean.
IMPORTANCE OF OCEANS
1. The oceans, comprising more than 70% of the Earth’s surface, occupy almost
three-fourth portion of the total area of the Earth.
2. Source of moisture. Oceans are the main source of moisture in the atmosphere.
Winds blowing over the oceans carry water vapour and cause rain on the land.
3. Oceans control the temperature
They have a great impact on the climate of the coastal areas. Oceans are
able to store up heat and then distribute it. Thus, ocean water can
moderate the high temperature of the summer season and low temperature
of the winter season and they control the extremes of temperature.
The coastal areas have maritime climate whereas the areas far from the
sea or ocean have continental type of climate.
4. Effects of ocean currents
The ocean currents modify the temperature and humidity of different
areas.
For example, warm ocean current increases the temperature and humidity
where as cold ocean current decreases the temperature of the coastal areas
where they flow.
5. Routes
Oceans not only separate continents and islands but they also serve to
connect one continent to another providing the cheapest and easy means
of transport.
Thus, oceans act as highways for trade and travel, e.g., the Suez Canal
route, the Panama Canal route and the North Atlantic route.
6. Storehouse of minerals
Oceans are the store houses of number of metallic and non-metallic
minerals.
Petroleum and natural gas are obtained from the sea floor. The Mumbai
High is an important oil producing region in India located offshore, in the
Arabian sea.
Salt is another important mineral obtained from the sea. Other minerals
like gold, diamond, Sulphur and raw materials are also found in the sea.
7. Food resources
Oceans are the largest source of fish. Most of the fishing grounds are in
the shallow continental shelves where sunlight can penetrate. So, they
have ideal conditions for the reproduction and growth of fish.
Some marine plants and animals are used for making medicines.
8. Power resources
The alternate rising and falling of the level of the sea and ocean water
(resulting of the gravitational attraction of the Sun and the Moon) is used
to produce electricity.
The countries like Russia, France and Japan produce electricity from
tidal energy. In India also tidal energy is produced in gulf of Khambat
and gulf of Kuchchh.
The difference in the temperature of surface water and sub-surface water
of the ocean can be used to generate energy with the help of floating
generators.
9. Recreational centre
Oceans serve as major recreational centres.
It should be a matter of great concern but unfortunately, men pollute them
by dumping dangerous chemicals, garbage into them.
Types of Oceans. There are five major oceans of the world. They are as follows:
1. The Pacific Ocean,
2. The Atlantic Ocean,
3. The Indian Ocean,
4. The Southern Ocean, and
5. The Arctic Ocean.
1. The Pacific Ocean
it is the largest ocean covering one - third of the total area of the Earth’s surface.
It is not only the largest but also, the deepest ocean with an average depth of 4,200
m.
It is roughly triangular in shape having base in the south and vertex in the north at
the Bering Strait.
The east - west extension of the Pacific Ocean is about 16,000 km (from east coast
of Asia to west coast of North America) and the north-south extension from Bering
Strait to Cape Adre (Antarctica) is about 15,000 km.
Pacific Ocean is bounded by North and South America on the east, Asia and
Australia on the west and Antarctica in the south.
Continental shelves along the coast of East Australia and Asia are broader while
they are less extensive along the coast of North and South America due to the
presence of Rocky and Andes Mountains near the coast.
There are many deep trenches in the ocean. Mariana Trench (about 10,800 m below
the sea level) is the deepest. Another one is the Philippine Trench ( about 10,380 m
below the sea level).
The vast Pacific ocean has more than 2,000 islands. Some of them are volcanic and
coral islands. The highest volcanic island from Hawaii, Tahiti and Samoa. There is
a string of volcanoes along the coastal margins of the continents.
The narrow Bering Strait separates North America from Asia.
2. The Atlantic Ocean
It is the second largest ocean. It was formed as a result of drifting of North and
South America to the west due to plate tectonic movements. It is still widening
by 1 cm each year.
The Atlantic Ocean is located between North and South America in the west and
Europe and Africa in the east. It extends from Greenland in the north to
Antarctica continent in the south.
It is narrowest in the north being enclosed by Greenland and Iceland. It broadly
opens into the Southern Ocean in the south.
It is roughly half the size of the Pacific Ocean covering about one-sixth of the
Earth’s total surface.
It resembles the shape of the letter “S”. The most striking feature of the Atlantic
ocean is the longitudinal extension of the Mid-Atlantic Ridge, which extends for
about 15,000 km from Iceland in the north to Bouvet Islands in the south.
This ridge is known as Dolphin Rise in the north and the Challenger Rise in the
south as it was discovered by the Challenger in 1973. The Mid-Atlantic Ridge
divides the Atlantic Ocean into two deep basins on either side.
The Atlantic Ocean is the busiest commercial highway of the world between
highly industrial regions of west Europe and north-east United States joining
some of the most important seaports of London and New York. Most of the
world’s greatest ports lie on its coasts.
The Atlantic Ocean has numerous seas on both the sides, few Islands and
continental shelf is found all along the ocean.
The important trenches are Puerto Rico Trench (8,385 m deep), South Sandwich
Trench (8,312 m deep) and Romanche Trench (7,631 m deep).
3. The Indian Ocean
It is the third largest ocean and the only ocean named after the name of a country,
i.e., Indian ocean after India. Its average depth is 4,000 m.
It is bound by Asia in the north, Africa in the west, Australia in the south east
and Antarctica in the south.
The tapering shape of Indian subcontinent in the north divides the Indian Ocean
into the Arabian Sea and the Bay of Bengal.
The Indian Ocean floor has new underlying relief features in comparison to the
Pacific and Atlantic Oceans. The Sunda Trench (7,450 m) is a deep trench in this
ocean.
A striking submarine ridge runs from Kanyakumari (Cape Comorin) in the north
to Antarctica in the sosouthIt is known as the Mid-Indian Oceanic Ridge.
There are many continental Islands like Sri Lanka and Madagascar. The islands
of volcanic origin are Andaman and Nicobar, Mauritius, etc. Lakshadweep
Islands are the coral Islands.
4. The Southern Ocean (Antarctic Ocean)
The ocean that surrounds the Antarctica continent forms the southern portion of
the Pacific, Atlantic and Indian Oceans.
Its maximum depth is 4,500 m.
It is recognized as a new ocean in a A.D. 2000 by the International
Hydrographic Organisation.
5. The Arctic Ocean
The Arctic Ocean is located around the North Pole.
It is the smallest of all the oceans. It is almost circular in shape and is surrounded
by the important countries of Europe, North America and Asia.
The Arctic Ocean is covered by thick ice around the North Pole. Much of it is
covered by pack ice throughout the year. The fringes of ice break up to form ice
bergs in short summer so the salinity of this ocean is very low.
The major seas are Beaufort Sea, Kara Sea and East Siberian Sea.
Answer the following questions
1. State the importance of Hydrosphere.
2. What is meant by antipodal balance of land and sea?
3. What percentage of Earth's surface is covered by Oceans and seas?
4. Give four importance of oceans
5. Name two most saline water bodies of the world.
Answers to Geography Worksheet-9
1. Endogenic forces are the internal forces that originate deep inside the earth
interior. They may be horizontal or vertical forces.
Exogenic forces - The external forces are the agents of gradation like running
water or river , wind, glacier etc.
2. Mountain- A natural elevation of the Earth surface rising more or less abruptly to
a submit and attaining altitude greater than 900 meter above the sea level with
slope making an angle of 25 degree to 35 degree with the horizontal plane is
known as a mountain.
3. Examples of Young Fold Mountains - The Himalayas, Andes, Alps and Rockies.
4. Plateau is an elevated tract of comparatively flat or leveled land usually having
steep slopes falling on the margins abruptly to lower land. For example Tibetan
Plateau.
5. A level or gentle undulating land with relatively minor differences in elevation
less than 150 m above the sea level is known as plain land.
6. As the river leaves mountains and enters the plain region the slope of the land
changes from state to gentle so it is difficult for the river to carry it surrounded
material (pebbles, boulders etc.) with it. The river starts depositing its load at the
foothill areas of the mountains and forms piedmont alluvial fans or plains in India.
It is known as the bhabar which is found along the foothill regions of the

Heat and energy
Most materials are subject to thermal expansion: a tendency to expand when heated and
to contract when cooled.Thermal expansion occurs when an object expands and becomes
larger due to a change in the object's temperature.
All three states of matter (solid, liquid and gas) expand when heated.
a.When a liquid is heated, it expands, irrespective of the temperature range. However,
water is an exception.
When water at 0ºC is heated, it contracts till 4ºC, instead of expanding. This
anomalous behaviour of water was explained by Thomas Charles Hope.
1.What is Heat?
Heat is a form of energy which flows.
It is the energy of random motion of molecules constituting the body
The S.I. unit of heat is joule J.
The other units of heat are calorie (cal) and kilocalorie (kcal)
1 cal = 4.186 J ∼ 4.2 J
2.Definition of Temperature:
Temperature is a quantity which tells the thermal state of a body (i.e., the degree of
hotness or coldness of the body).
It determines the direction of flow of heat when two bodies at different temperatures are
placed in contact
The S.I. unit is kelvin (K)
The other most common unit is degree celsius (°C)
T K = 273 + t °C
3.Thermal Expansion:
The expansion of a substance on heating is called the thermal expansion of that substance
a.The increase in length is called linear expansion.
b.The increase in area is called superficial expansion.
c.The increase in volume is called cubical expansion
4.Variation of density with temperature
a.Density decreases with the increase in temperature.
● In case of solids, the decrease is very small
● In case of liquids and gases, the decrease in density is considerable
5.Variation in volume with temperature
Try solve following problems:
1. Differentiate between heat and temperature.
2. Why does a piece of ice when touched with hand, appear cool ?explain
3. Draw a graph to show the variation in density of water with temperature in the
temperature range from zero degree celsius to 10 degree Celsius.
4. What do you mean by anomalous expansion of water?
5. Name two substances which contract on heating.
6.Draw a graph to show the variation in volume of water with temperature in the
temperature range from zero degree celsius to 10 degree Celsius.
7. Read Hope's experiment to demonstrate the anomalous expansion of water.
8. At what temperature the density of water is maximum state its value.

HYDROGEN (CHAPTER-6) CONTINUED
Another very important use of hydrogen is
OXIDATION- REDUCTION REACTIONS: There are different ways of defining
oxidation and reduction
1.In terms of HYDROGEN transfer
Oxidation involves removal of HYDROGEN from a substance.
H2S + Cl2 2HCl + S
Reduction involves addition of HYDROGEN to a compound.
H2S + Cl2 2HCl + S
2. In terms of OXYGEN transfer
Oxidation involves addition of OXYGEN to a substance.
Cu + O2 2CuO
Reduction involves removal of OXYGEN from a compound
CuO + H2 Cu + H2O
IN TERMS OF OXIDATION REDUCTION
Hydrogen transfer Loss of hydrogen Gain of hydrogen
Oxygen transfer Gain of oxygen Loss of oxygen
OXIDISING AGENTS: are substances that lose oxygen or gain hydrogen They
themselves get reduced.
Examples of Oxidizing agents: O2, Cl2, MnO2, K2Cr2O7
REDUCING AGENTS: Reducing agents are substances that lose hydrogen or gain
oxygen. They themselves get oxidized.
Examples of Reducing Agents: H2, HCl, NH3, Carbon
NOTE: A substance which gets oxidized is a reducing agent
A substance which gets reduced is an oxidizing agent
REDOX REACTIONS: A chemical reaction in which oxidation and reduction occur
simultaneously is known as redox reaction. It involves oxidation of one substance and
reduction of the other.
EXAMPLE 1:
Fe2O3 loses oxygen to form Fe, since there is loss of oxygen it is reduction.
CO gains oxygen to form CO2, since there is gain of oxygen it is oxidation
Because both reduction and oxidation are going on side-by-side, this is known as
a redox reaction.
In the above equation:
• Fe2O3 is reduced (as it has lost oxygen)
• CO is oxidized (as it has gained oxygen)
• Fe2O3 is the oxidizing agent (as it is getting reduced)
• CO is the reducing agent (as it is getting oxidized)
• Fe is the reduced product
• CO2 is the oxidized product
EXAMPLE 2:
In the above equation:
Fe3O4 is reduced( as oxygen is removed)
H2 is oxidized(as oxygen is added)
Fe3O4 is oxidizing agent(as it gets reduced)
H2 is reducing agent(as it gets oxidized)
Fe is reduced product
H2O is oxidized product
ANSWER THE FOLLOWING:
1.Define oxidation and reduction
2.Define oxidizing agent and reducing agent.
3.In the given equation

CHAPTER-RESPIRATION IN PLANTS
Respiration –It is a catabolic process of releasing energy from a simple sugar that is
glucose for carrying out life processes.
Three important characteristics of respiration in this equation are as follows:
1. The breakdown of glucose to carbon dioxide and water does not occur in a single
step but in a series of chemical steps. These steps occur in two major phases-a)
glycolysis (glucose into pyruvate) occurring in cytoplasm) b) Krebs cycle
(pyruvate into carbon dioxide, water and ATP) occurring in mitochondria.
2. Each breakdown step is due to a particular enzyme.
3. The energy liberated in the breakdown of the glucose molecule is not all in the
form of heat, but a large part of it converted into chemical energy in the form of
ATP (Adenosine triphosphate).
ATP is the energy currency of the cell.
Living organisms show two types of metabolic activities:
A) Anabolic (constructive or biosynthetic processes) it consumes energy.
B) Catabolic (destructive or breaking down processes), it gives out energy for use by an
organism. Example-respiration.

WORKSHEET 11
COOPERATIVE SOCIETY
CHAPTER:8
A business organization can take many forms. One such form is that of a cooperative
society. Such societies have unique features of joint ownership and democratic
leadership.
A cooperative society is not a new concept. It prevails in all the countries, this is almost a
universal concept. The cooperative society is active in all countries worldwide and is
represented in all the sectors including agriculture, food, finance, healthcare, etc.
To protect the interest of weaker sections, the co-operative society is formed. It is a
voluntary association of persons, whose motive is the welfare of the members.
MEANING OF CO-OPERATIVE SOCIETY
A Co-operative Society is a voluntary association of people who come together and
invest their small savings to form the organization. The Co-operative Society is formed
for the mutual benefit of all the members. The members of the co-operative society are
people who come together and invest their small savings to form the organization which
will work towards their common cause. The Co-operative Society is formed with an idea
of supporting each other to achieve a common economic objective. For example, the
farmers may come together and form a co-operative society to work jointly and take
advantage of economies of scale. When they work together they will have a better
bargaining power for buying raw materials. They will also enjoy a better bargaining
power while selling their agricultural output. Minimum no of members required to start a
cooperative society is 10. However, there is no upper limit to the number of members that
a cooperative society can have.
ACCORDING TO THE INDIAN COOPERATIVE SOCIETIES ACT,1912
Cooperative organisation is “ a society which has its objectives for the promotion of
economic interests of its members in accordance with cooperative principles.”
‘EACH FOR ALL AND ALL FOR EACH’ AND SELF-HELP THROUGH
MUTUAL AID’ ARE THE GUIDING PRINCIPLES OF COOPERATION.
FEATURES OF COOPERATIVE SOCIETY
1.Voluntary association: Everyone having a common interest is free to join a cooperative
society and can also leave the society after giving proper notice. He can withdraw his capital but
cannot transfer his share to another person.
2. Religious and political neutrality: The membership of cooperative society is open to all
irrespective of caste, creed, religion or political affiliation. New members are always welcome to
join the society. Cooperative societies represent universal brotherhood.
3. Separate legal entity: After registration a cooperative society becomes a distinct body
independent of its members. It can own property and make contracts in its own name. It becomes
an autonomous and self- governing organisation.
4. One man one vote: Every member has one vote irrespective of number of shares held by him.
Rich persons holding more shares cannot dictate terms. The organisation of a cooperative society
is democratic and all members have an equal voice in its management.
5. Service motive: The main aim is to serve its members and not to maximize the profit.
Aim of cooperative society is to provide service to its members. Its moto is ‘Each for all and all
for each.’ For example, in a Consumer Co-operative Store, goods are sold to its members
at a reasonable price by retaining a small margin of profit. It also provides better quality
goods to its members and the general public 6. Registration: Registration of a cooperative society is compulsory. Registration is done by the
Registrar of Cooperative societies.
7. State control: They have to abide by the rules and regulations framed by government for
them.
8. Distribution of surplus: The profit is distributed on the basis of volume of business transacted
by a member and not on the basis of capital contribution of members. For example, in a
consumer co-operative store only a small part of the profit is distributed to members as
dividend on their shares; a major part of the profit is paid as purchase bonus to members
on the basis of goods purchased by each member from the society.

9. Self-help through mutual cooperation: Co-operative Societies thrive on the principle
of mutual help. They are the organisations of financially weaker sections of society. Co-
operative Societies convert the weakness of members into strength by adopting the
principle of self-help through mutual co-operation. It is only by working jointly on the
principle of “Each for all and all for each”, the members can fight exploitation and secure
a place in society.

ANSWER KEY OF PREVIOUS WORKSHEET(JOINT STOCK COMPANY)
Ans:1 Joint Stock Company is a voluntary association of persons to carry on the business.
It is an association of persons who contribute money which is called capital for some
common purpose. These persons are members of the company. The proportion of capital
to which each member is entitled is his share and every member holding such share is
called shareholders and the capital of the company is known as share capital.
Ans:2 One Person is a Company type to start a business in India. OPC is a company
which is run by the single person who is also the Director & Shareholder and provides
limited liability to the shareholder. OPC is similar to Private Limited Company under
Companies Act 2013.
Ans:3 Perpetual succession means that a company's life is not determined by the
longevity of its members, shareholders, promoters, directors, employees or anyone else.
If a shareholder dies, or hypothetically, all the shareholders die, only their shares in the
company will be transferred to new people. If even a key director resigns, she will be
replaced but the company will continue on.
Ans:4 Being an artificial person a company has its own legal entity separate from its
members. It can own assets or property, enter into contracts, sue or can be sued by
anyone in the court of law. Its shareholders can not be held liable for any conduct of the
company.
Ans:5 Common Seal means a metal stamp for stamping documents with the name of the
company to show that they have been approved officially. In other words, Common Seal
is the official signature of the company and each company shall have only one seal, on its
incorporation. Being an artificial person a joint stock company cannot sign any
documents thus this common seal is the company’s representative while dealing with the
outsiders. Any document having common seal and the signature of the officer is binding
on the company.

range= 21-5 = 16
VARIATE: A particular value of a variable.
FREQUENCY: The number of times an observation occurs.
FREQUENCY DISTRIBUTION: The tabular arrangement of data showing the
frequency of each observation.
RAW OR UNGROUPED DATA: Data obtained in original form.
ARRAY: An arrangement of raw data in ascending or descending order of magnitude.
EXAMPLE: The sale of shoes of various sizes at a shop, on a particular day is given
below:
7, 8, 5, 4, 9, 8, 5, 7, 6, 8, 9, 6, 7, 9, 8, 7, 9, 9, 6, 5, 8, 9, 4, 5, 5, 8, 9, 6
The above data is clearly raw data.
From this data, we may construct a frequency table,
GROUPED DATA:
To put the data in more condensed form, we make GROUPED FREQUENCY
DISTRIBUTION TABLE. For that, we make groups of suitable size, and mention the
frequency of each group.
Each group into which the raw data is condensed, is called a class-interval.
e.g. 10-20, 20-30, 30-40……so on.
And the figure on the left side of a class-interval is its lower limit and that on its right
side is its upper-limit.
TYPES OF GROUPED FREQUENCY DISTRIBUTION:
1. EXCLUSIVE FORM (or Continuous interval form):
A frequency distribution in which lower-limit of the class is included and upper-
limit is not included.
EXAMPLE: The marks obtained by 40 students of a class in an examination are
given below. Present the data in the form of a frequency distribution using equal
class-size, one such class being10-15(15 not included).
3, 20, 13, 1, 21, 13, 3, 23, 16, 13, 18, 12, 5, 12, 5, 24, 9, 2, 7, 18, 20, 3, 10, 12, 7,
18, 2, 5, 7, 10, 16, 8, 16, 17, 8, 23, 21, 6, 23, 15

Present the data in the form of frequency distribution table in discontinuous
interval form, taking class intervals 1-10, 11-20, and so on.
SOLUTION:
Here, the class 1-10 means, 1 and 10 both are included)
IMPORTANT TERMS RELATED TO GROUPED DATA:
CLASS-SIZE: The difference between the upper limit and lower limit of the
class.
CLASS-MARK OF A CLASS= 𝑢𝑝𝑝𝑒𝑟 𝑙𝑖𝑚𝑖𝑡+𝑙𝑜𝑤𝑒𝑟 𝑙𝑖𝑚𝑖𝑡
2.
RULE OF CONVERTING INCLUSIVE TO EXCLUSIVE FORM:
To convert data given in discontinuous form to the continuous form, we subtract
the adjustment factor from each lower limit and add the adjustment factor to each
upper limit to get the true limits.
Adjustment factor=𝒍𝒐𝒘𝒆𝒓 𝒍𝒊𝒎𝒊𝒕 𝒐𝒇 𝒐𝒏𝒆 𝒄𝒍𝒂𝒔𝒔−𝒖𝒑𝒑𝒆𝒓 𝒍𝒊𝒎𝒊𝒕 𝒐𝒇 𝒑𝒓𝒆𝒗𝒊𝒐𝒖𝒔 𝒄𝒍𝒂𝒔𝒔

CONCEPT OF CONSUMPTION
“Consumption is the beginning and end of all human activities”.
“Consumption means using up of goods and services for satisfaction of human
wants”.
Consumption is defined as spending for acquisition of utility, is a major concept
in economics and is also studied in many other social sciences. It is seen in contrast
to investing, which is spending for acquisition of future income
According to mainstream economists, only the final purchase of newly
produced goods and services by Individuals for immediate use constitutes
consumption.
Meaning: Human wants can be satisfied only by using up goods and services.
When goods are consumed, utility in them is either destroyed or lessened. Thus
consumption means destruction or lessening of goods to satisfy human wants.
If Production means creation or addition of utility, then consumption is the using
up of the utility of goods and services for the satisfaction of human wants.
Remember, if any commodity is destroyed without satisfying human want, it is not
called consumption.
For Example- if some goods such as car, watch, washing machines, etc., are
destroyed in a house-fire or due to some other natural calamities, it will not be
treated as consumption. Another noteworthy point regarding consumption is that
there is no time gap between consumption and production of services. These two
go simultaneously. But there generally exists a time gap between the consumption
and production of material goods such as pen, watch, TV set, etc.
Kinds (or Forms) of Consumption
Consumption may be of the following types:
Final Consumption or Direct Consumption. When a commodity is consumed
directly for satisfaction of human want, it is called direct consumption or final
consumption. Example: Consumption of Cold Drink like Pepsi or Quality Walls-
ice-cream.
Productive Consumption or Indirect Consumption
When a commodity / commodities is used in the production of another
commodity, it is called Productive consumption or indirect consumption.
Examples - (i) Use of sugarcane by a sugar mill
(ii) Use of cotton yarn by a cotton textile mill.
Quick Consumption: When utility of a commodity is finished or destroyed the
moment it is consumed, it is called quick consumption. For instance, the utility of
a glass of mango- shake is completely destroyed the moment we consume that
glass of mango- shake. Consumption of all single-use consumer goods falls
under this category.
Slow Consumption: When a commodity gives utility for a long period of time, it
is called slow consumption. The consumption of consumer durables such as watch,
washing machine, television, home theatre, microwave oven etc., is slow
consumption.
Wasteful Consumption: When a commodity loses its utility without satisfying
any want, it is treated as wasteful consumption. For example, if newly stitched
clothes catch fire and are reduced to ashes, it will not be called consumption. You
may call it wasteful consumption.
Importance of Consumption:
Modern economists rightly emphasize the importance of consumption.
Consumption is the beginning as well as the end of all economic activity. A man feels
a desire and then he makes an effort to satisfy it. When the effort has been made,
the result is the satisfaction of the want.
Want is thus the beginning and its satisfaction the end of our economic effort.
Consumption is regarded as the be-all and the end-all of all economic activity. In
other words, consumption is the beginning as well as the end of all economic
activity. It is consumption which gives the initial push to production. Production,
thus, is directed and stimulated by consumption.
Sustainable Consumption
Sustainable consumption is the use of products and services in a way that minimizes
the impact on the environment, so that human needs can be met not only in the
present but also for future generations. When sustainable consumption is practiced,
resources are used wisely and waste products and pollution are minimized. The
main way this is achieved is by doing more and better with less. In other words, we
can find ways to meet our needs and desires without depleting our planet's finite
natural resources.
This might include carpooling, using renewable energy sources, such as solar or
wind power, developing alternative fuel sources, such as bio-fuels, for our
transportation needs and using environmentally friendly cleaning products.
Practicing sustainable consumption can ensure that the environment has resources
available long into the future. However, in most industrialized and developed
nations, consumption patterns are not sustainable.
Their products and services rely on too many natural resources and create too many
harmful emissions when consumed. For example, most developed countries rely on
non-renewable fossil fuels for their transportation needs. As more drivers hit the
roads and more fuel is consumed, fossil fuel reserves are depleted, and because fossil
fuels emit greenhouse gases into the atmosphere when they are burned, more
consumption means more pollution. So in order to counter these problems we need
sustainable consumption.
Thus Sustainable consumption means the use of products and services that have the
least effect on environment. This will leave enough resources for the future
generations to meet their needs. It will help in bringing a better quality of life while
minimizing the use of natural resources and toxic materials as well as the emissions
of waste and pollutants.
Sustainable consumption is the use of material products, energy and immaterial
services in such a way that it minimizes the impact on the environment, so that
human needs can be met not only in the present but also for future generations.

Answer key of Economics Worksheet-8
Q1. Define the term Production?
Ans: Production means creation of utility. Hence ‘Production is a physical process
carried out by an enterprise in which labour and capital along with land are used to
convert inputs into output of goods and services. It can also be defined as activity
that results in value added.’
Q2. Name the four factors of Production?
Ans: Land, Labour, Capital, and Organisation.
Q3. Explain any two factors of Production in detail?
Ans: LAND-
As the Penguin Dictionary of Economics has put it: “Land in economics is taken to
mean not simply that part of the earth’s surface not covered by water, but also all
the free gifts of nature’s such as minerals, soil fertility, as also the resources of sea.
Land provides both space and specific resources”.
From the above definition, it is quite clear that land includes farming and building
land, forests, and mineral deposits. Fisheries, rivers, lakes, etc. all those natural
resources (or gifts of nature) which help us (the members of the society) to produce
useful goods and services. Thus Land in economics, means not only the surface of
the earth, but all those free gifts of nature,the supply of which can be regulated.
LABOUR-
By labour, we mean all types of human work - physical or mental - done with a view
to earn income.
Labour is also a primary factor of production. The distinctive feature of the factor
of production, called labour, is that it provides a human service. It refers to human
effect of any kind—physical and mental— which is directed to the production of
goods and services. ‘Labour’ is the collective name given to the productive services
embodied in human physical effort, skill, intellectual powers, etc. The term covers
clerical, managerial and administrative functions as well as skilled and unskilled
manual work.

The Human Anatomy and Physiology
Functions of the Skeletal System
1. Protection: The skeletal system protects a number of vital and delicate organs.
The bones reduce the risk of injuries to these delicate organs. For example; the
skull protects the brain, middle ear and inner ear. The ribs and sternum protects the
lungs, heart and the major blood vessels.
2. Movement: Bones, skeletal muscles, tendons, ligaments and joints functions
together for making movements.
3. Support: The skeletal system is the framework of the body. It supports the softer
tissues and provides space for the attachment of skeletal muscles.
4. Production of Blood Cells: In the long bones, there is a cavity that is filled with a
substance called bone marrow. In this bone marrow new blood cells are produced
and damaged blood cells are repaired.
5. Storage of Minerals: Bone tissues store various minerals such as calcium and
phosphorus. Red bone marrow in bones also stores iron.
Classification of Different Types of Joints
Joints: A joint is a union of two or more bones of the skeleton. Bones are joined to each
other by ligaments.
Classification of Joints: According to mobility of joints they can be classified into the
following categories:
1. Fibrous or Immovable Joints
2. Cartilaginous or Slightly Moveable Joints.
3. Synovial or Freely Movable Joints.
1. Fibrous or Immovable Joints: These joints are called
immovable joints because they are fixed. There is no
movement between the concerned bones. These joints
are found the bones of skull and face.
2. Cartilaginous or Slightly Moveable Joints
In these joints, surfaces of the bones are
separated by a pad of white fibrocartilage and
only slight movement is possible. Example of
slightly movable joints are pubic symphysis
of pubis and joints between vertebrae.
3. Synovial or Freely Movable Joints
These joints include most of the joints of the
body. The adjacent ends of the bones are
covered with hyaline cartilage and are
surrounded by a fibrous articular capsule,
which is strengthened by ligaments.
The freely movable joints are further
classified into the following six categories:
i. Gliding Joint These joints permit gliding movements
only. In these joints, the articular surfaces glide over
each other. These are found between tarsal bones of
ankle and between carpal bones of wrist.
ii. Hinge Joints: These joints permit angular movement
in one direction, like a door on its hinges. The movements of these joints are
called flexion and extension, e.g., in the elbow joint, in
the knee joint and the joints of phalanges.
iii. Condyloid Joints: These joints allow an angular
movement in two directions, e.g., wrist joint. Movements
of this joint include flexion, adduction, abduction and
circumduction, but no rotation.
iv. Saddle Joints: These joints permit a great
freedom of movements e.g., joint of thumb.
It enables the thumb to oppose the fingers.
v. Ball and Socket Joints: These joints have an
angular movement is all directions and a pivot
movement. In this form of joint, a more or less
rounded head lies in cup like cavity. Shoulder
joint and hip joint are the examples of ball and
socket joints.
vi. Pivot Joint: These are joints with rotary
movement in one axis. In pivot joint, a ring
rotates around a pivot. For example, the
movements of head, where the ring like atlas
rotates round the peg-shaped process of the axis.
Types of Joint Movements in Physical Education
a) Flexion: Bending parts at a joint so that the angle between them decreases and
parts come closer together (bending the femur
and tibia at the knee and humerus and radius and
ulna at the elbow
b) Extension: Straightening parts at a joint so that
the angle between them increases and the parts
move farther apart. ( straightening the femur and
tibia at the knee and humerus and radius and
ulna at the elbow)
c) Abduction: Moving a part away from the midline (lifting upper limb horizontally
to form a right angle with the side of the body).
d) Adduction: Moving a part away from the midline of the body( returning the upper
limb from the horizontal position to the side of the body.
e) Circumduction: Circumduction is that movement which takes place between the
head of the bone and its articular cavity. This kind of movement is best seen in the
shoulder and hip joints.
t the hip joint that brings the anterior surface of the limb toward the midline of
the body.
f) Rotation: Rotation is a form of movement in which a bone moves around a
central axis without undergoing any displacement from this axis. E.g. twisting the
head from side to side.
g) Internal Rotation: The movement of the arm at the shoulder joint or the thigh at
the hip joint that brings the anterior surface of the limb toward the midline of the
body. It is also called medial rotation.
h) External Rotation: The movement of the arm at the shoulder joint or the thigh at
the hip joint that brings the anterior surface of the limb away the midline of the
body. It is also called lateral rotation.
i) Hinge Joints: These joints permit angular movements in one direction. The
movements of these joints are flexion and extension.
j) Pivot Joint: These are the joints with rotary movement in one axis. It allows
rotation only.
k) Ball and Socket Joints: These joints have an angular movement in all direction
and a pivot movement. It allows flexion, extension, abduction, adduction,
circumduction, internal and external rotation.
l) Saddle Joint: In this joint a bone fits into a saddle-shaped surface on another
bone. These joints allow flexion, extension, abduction, adduction, and
circumduction.
Benefits of Exercise on the Skeletal System
If exercises are performed regularly they are beneficial to our skeletal system in
various ways that are described below:
1. Increase Flexibility: Joints assist us to move in a more flexible way. Exercise
enhances the flexibility of the joints. It means that the range of movement of the
joints increases when exercises are performed regularly.
2. Makes Bones Stronger: Regular exercise strengthens our skeletal system. If we
do not perform exercise regularly it will lead to the loss of bone density which
results in weak and fragile bones.
3. Strengthen Joints: Regular exercise helps us to maintain our joints in sound
health and reduces the chance of any degenerative joint disease.
4. Good Posture: Regular exercise helps in maintaining good body posture and
appropriate skeletal alignment. Some of the postural exercises are very effective in
this regard with the attainment of better posture, the risks of suffering from
musculoskeletal problems are reduced significantly.
5. Brings about a Healthy Lifestyle: Regular exercise regimen will go a long way
in keeping us healthy. We can perform our day to day activities efficiently as well
as effectively by performing regular exercise.
6. Improves Soft Tissue: Soft tissues like tendons, ligaments, skin, fibrous tissues,
fats, muscles and blood vessels surround the bones of our body. They act as a
shock absorber that protects our bones from damage or fracture. With the help of
regular exercise our soft tissues become stronger which ultimately help in
protecting our bones.

INTRODUCTION TO JAVA
Character Set
The character set is a set of alphabets, letters and some special characters that are
valid in Java language.
The smallest unit of Java language is the characters need to write java tokens.
These character set are defined by Unicode character set.
Whenever we write any Java program then it consists of different statements. Each
Java Program is set of statements and each statement is set of different Java
programming lexemes. In Java Programming each and every character is
considered as a single lexeme. i.e Basic Lexical Element.
Character Set Consists Of
Alphabets
Java accepts both lowercase and uppercase alphabets as variables and functions.
Uppercase: A B C ................................... X Y Z
Lowercase: a b c ...................................... x y z

Unicode System
Unicode is a universal international standard character encoding that is capable of
representing most of the world's written languages.
Why java uses Unicode System?
Before Unicode, there were many language standards:
ASCII (American Standard Code for Information Interchange) for the United States.
ISO 8859-1 for Western European Language.
KOI-8 for Russian.
GB18030 and BIG-5 for chinese, and so on.
Problem
This caused two problems:
A particular code value corresponds to different letters in the various language standards.
The encodings for languages with large character sets have variable length.Some
common characters are encoded as single bytes, other require two or more byte.
Solution
To solve these problems, a new language standard was developed i.e. Unicode System.
In unicode, character holds 2 byte, so java also uses 2 byte for characters.
lowest value:\u0000
highest value:\uFFFF
