1. Use the formula W=FxD to answer the following question. A force of 10 newtons is used to push a 5-kilogram object a distance of 18 meters. What is the amount of work exerted on the object? A. 50 joules B. 90 joules C. 180 joules D. 900 joules​

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. (0.00644 kg/s, 800 kpa, 2.03)
