g A sample of blood is placed in a centrifuge of radius .15 m. The mass of a red corpuscle is 3.0 x 10-16 kg, and the magnitude of the force required to make it settle out of the plasma is 4.0 x 10-11 N. What does the angular speed need to be

To travel at constant speed, a car engine provides 24kw of useful power. the driving force on the car is 600n. at what speed does it travel?

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

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.
