Abird sitting on the limb of a tree is moving about 30 km/s with respect to the sun. if the bird takes 1 second to drop down to a worm below, the worm would be 30 km downrange from the bird when it reached the ground. this faulty reasoning is best countered with newton's

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.
