Question

140 students sit in an auditorium listening to a physics lecture. Because they are thinking hard, each is using 125 W of metabolic power, slightly more than they would use at rest. An air conditioner with a COP of 5.0 is being used to keep the room at a constant temperature. Part A What minimum electric power must be used to operate the air conditioner? Express your answer to two significant figures and include the appropriate units. P = SubmitMy AnswersGive Up 140 students sit in an auditorium listening to a physics lecture.

Explanation / Answer

Power required = 140 students x 125 W/student / 5.0
Power required = 3500 W
