Arolling ball has an initial velocity of 1.6 meters per second. if the ball has a constant acceleration of 0.33 meters per second squared in the same direction as its movement, what is its velocity after 3.6 seconds?

What is created when solids,liquids,an gases mix with one another

The speed of light can be used to measure the

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.
