A sample of water vapor (H2O) occupies 3.50 L at 265 K and 50.0 kPa. What is the new volume when the sample is adjusted to STP?

A2-kg bowling ball is 2.5 meters off the ground on a post when it falls. just before it reaches the ground, it is traveling 7 m/s. assuming that there is no air resistance, which statement is true?

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (
