Assume that an average city uses about 8.5×1013J of energy in a day. The mass is 9.4kg
A fission-based nuclear bomb (such as those used in World War II) uses the same nuclear reactions and an amount of fuel similar to what you calculated in Part A. However, by allowing an uncontrolled chain reaction to occur, all of the bomb's energy can be released in about 1.0×10?6s.
What is the average power Pavg of such a nuclear bomb?
