You and your friends prepare to play a game of basketball. You push the net across the court to get it in position. You exert a horizontal force of 24 N, while friction opposes the motion of the net with a force of 19 N. You slide the net a distance of 2 m. What is the work done on the basketball net? Show your work. Include the correct unit in your answer.

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.
