A5.08 g object moving to the right at 28.5 cm/s makes an elastic head-on collision with a 10.16 g object that is initially at rest. 28.5 cm/s 5.08 g 10.16 g find the velocity of the first object immediately after the collision. the acceleration of gravity is 9.8 m/s 2 . answer in units of cm/s.

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa.
