Aheat pump has a coefficient of performance of 3.0 and is rated to do work at 1500 w. a. how much heat can it add to a room per second? b. if the heat pump acted as an air conditioner in the summer, what would you expectits coefficient of performance to be assuming all else stay the same? what is the rise in temperature of the air in the room in part (a) if the heat pump is run for 5 minutes? assume (unrealistically) no loss of heat from the room (of dimensions 10m x8m x 3m), and for ease of calculation assume air composed of only nitrogen (molar mass 2be, density at ambient temps 1.25 kg/m3)

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used 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 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
