Ababy elephant is stuck in a mud hole. to pull it out, game keepers use a rope to apply a force fa, as part a of the drawing shows. by itself, however, force fa is insufficient. therefore, two additional forces fb and fc are applied, as in part b of the drawing. each of these additional forces has the same magnitude f. the magnitude of the resultant force acting on the elephant in part b of the drawing is k times larger than that in part a. find the ratio f/fa when k = 2.10. the angle is 16 degrees.
the answer must be in 4 significant figures.

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.
