A Ferris wheel on a California pier is 38 m high and rotates once every 26 seconds in the counterclockwise direction. When the wheel starts turning, you are at the very top. What is your speed v? Express your answer with appropriate units

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator.
