a) A hot water heater in a residential home runs for an average of 3 hours per day with a heat energy input of 4.1 kW. What would be the annual cost for hot water in this home using an electric hot water heater if the cost of electricity is $0.13/kWh [round your final answer to zero decimal places]? b) A hot water heater in a residential home runs for an average of 3.2 hours per day with a heat energy input of 3.7 kW. What would be the annual cost for hot water in this home using a gas hot water heater if the cost of natural gas is $0.33/m3? The gas water heater can get 23 MJ of energy from 1 m3 of natural gas. [round your final answer to zero decimal places]?
