Question: A heat pump is used to heat a building. The outside temperature is -5.0'C, and the temperature inside the building is to be maintained at

A heat pump is used to heat a building. The outside temperature is -5.0'C, and the temperature inside the building is to be maintained at 22oC. The pump's coefficient of performance is 3.8, and the heat pump delivers7.54 MJ as heat to the building each hour. If the heat pump is a Carnot engine working in reverse, at what rate must work be done to run it?
