For a home in minneapolis, the design heating load is 46,000 btu/hr and the design cooling load is 64,000 btu/hr, and the carnot coefficient of performance (cop) for the heat pump is 8.5, while the carnot cop for the refrigerator is 11: a) calculate the minimum electric power required to maintain the indoor condition at 70'f in kw, and b) determine the outdoor temperature in both ℉ and in ℃ c) if work of a single phase source is given by the formula w-v* i where i is the current in (a) and v is the voltage in (v), and voltage in minneapolis is 110 volts, what is the current for both heating and cooling

Atennis player used a tennis racket to hit a tennis ball with a mass of 0.25 kg with a force of 5.25 newtons. how does the force the tennis racket exerted on the tennis ball compare with the force the tennis ball exerted on the tennis racket? a. the force of the tennis racket on the tennis ball is equal in magnitude and opposite in direction to the force the tennis ball exerted on the tennis racket. b. the force of the tennis racket on the tennis ball is equal in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. c. the force of the tennis racket on the tennis ball is less in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. d. the force of the tennis racket on the tennis ball is greater in magnitude and opposite in direction as the force the tennis ball exerted on the tennis racket.
