Which is one way that waves erode coastlines? Back-and-forth movement loosens sediment and rock. Large rocks are picked up and deposited in new areas. Continuous impacts build up sediment and rock. Loose sediment is picked up and blown to other locations.

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.
