Some satellites move around Earth in polar orbits, that is, in a north to south direction,
rather than west to east. Can scientists who want to put a satellite into a polar orbit take
advantage of Earth’s rotation to give the rocket a “boost”? Explain.
Thank you if you help me out.

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.
