Apendulum is made up of a small sphere of mass 0.500 kg attached to a string of length 0.750 m. the sphere is swinging back and forth between point a, where the string is at the maximum angle of 35.0∘ to the left of vertical, and point c, where the string is at the maximum angle of 35.0∘ to the right of vertical. the string is vertical when the sphere is at point b. calculate how much work the force of gravity does on the sphere from a to b. express your answer with the appropriate units.

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.
