5] In nuclear fission and fusion reactions mass is converted into energy
[5] In nuclear fission and fusion reactions mass is converted
into energy. The average person in US uses around 100,000,000 J of energy per year.
(a) Calculate the yearly energy consumption for a US population of 300 million.
(b) Using Einstein’s famous formula, E = m c^2, calculate the energy that would be released if a 60 kg person were converted entirely into energy.
(c) How many years would this amount of energy support a population of 300 million?
