Everybody knows that “water seeks its own level,” but very few people know why water seeks its own level. The reason has most to do with

1. atmospheric pressure.2. water pressure depending on depth.3. water’s density.

The density of the block of wood floating in water is

An astronaut on Earth notes that in her soft drink an ice cube floats with 9/10 its volume submerged. If she were instead in a lunar module parked on the Moon, the ice in the same soft drink would float with

Consider a boat loaded with scrap iron in a swimming pool. If the iron is thrown overboard into the pool, will the water level at the edge of the pool rise, fall, or remain unchanged?

The weight of the stand and suspended solid iron ball is equal to the weight of the container of water as shown above. When the ball is lowered into the water the balance is upset. The amount of weight that must be added to the left side to restore balance, compared to the weight of water displaced by the ball, would be

1. half. 2. the same.3. twice. 4. more than twice.

Gently push down on the pan of the scale and the display shows an increase in force. Likewise if you do the same on the rim of the beaker. But what if you immerse your fingertip in the water, without touching the beaker? Then the scale reading

1. doesn’t change.2. shows an increase.3. shows a decrease.
