Chapter 5, Problem 53EAP

Electric Bill. Your electric utility bill probably shows your energy use for the month in units of kilowatt-hours. A kilowatt- hour is defined as the energy used in 1 hour at a rate of 1 kilowatt (1000 watts); that is,  1 kilowatt-hour  × 1 kilowatt  × 1 hour . Use this fact to convert 1 kilowatt-hour into joules. If your bill says you used 900 kilowatt-hours, how much energy did you use in joules?
