Q1. I don’t understand how in adiabatic processes if there is no heat flow in or out, the temperature can still change?

Q2. I know that W = –(U2 – U1) for adiabatic process, and this makes W = nCV(T1 – T2), but if the gas is cooling and decreasing in temperature, wouldn't it also decrease in volume, making work negative because W = p(V2 – V1)?

Q3. In a mechanical engine, such as a car engine, would the engine be 100% efficient if friction didn't exist?

2. Why do we only use an integral to calculate the moments of inertia for spheres or cylinders and not other shapes?

A. the same acceleration and the same orbital period.

B. 1/2 the acceleration and 1/2 the orbital period.

C. 1/4 the acceleration and 1/4 the orbital period.

D. 1/4 the acceleration and the same orbital period.

E. none of the above.

You put your spacecraft into a circular orbit around the forest moon of Endor, which has 1/2 the radius of Earth and has 1/4 the Earth’s mass. Compared to being in an orbit of the same size around Earth, when in orbit around the forest moon of Endor your spacecraft will have

A problem for you

An object moves on a curved path as shown. It speeds up as it moves from point 1 to point 2.

• Draw the vector(the change in velocity from point 1 to point 2)• Draw the average acceleration vector

for the time interval from 1 to 2. This is an estimate of the direction of the instantaneous acceleration vector at point A, midway between points 1 and 2.

A problem for you

A particle of mass m is free to move along the x–axis. The only force on the particle is a conservative force given by the potential energy function

In this expression and are positive constants.• Find the points at which the particle is in equilibrium.• Determine which of the points of equilibrium are stable and which are unstable.
