Asample of a low-density gas is initially at room temperature and has pressure p0 . the gas is warmed at constant volume until the pressure is 2p0 .

compared to the initial celsius temperature of the gas, the final celsius temperature is

a. greater by a factor of more than 2.

b. greater by a factor of 2.

c. greater by a factor between 1 and 2.

d. the same.

e. less

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

An owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
