Aboat at rest on the ocean moves up and down as water waves pass beneath it. what can be concluded about the movement of the water particles within a water wave? a) water particles move vertically, up and down in circles. b) water particles move horizontally with the wave energy. c) water particles move in the same direction as the wave energy. d) water particles move horizontally while wave energy moves in circles.

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
