An air-conditioning system is used to maintain a house at 72oF when the temperature outside is 90oF. If this air-conditioning system draws 5 hp of power when operating, determine the maximum rate of heat removal [BTU/min] from the house that it can accomplish.

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?
