How much mass of`" ^235U` is required to undergo fission each day to provide 3000 MW of thermal power? Average energy per fission is 202.79 Mev?

A person trying to lose weight by burning fat lifts a mass of 10 kg upto a height of 1m is 1000 time . Assume that the potential energy lost each time be lower the mass is dissipated . How much far will be use up considering the work done only when the weight is lifted up ? Far supplies 3.8 xx 10^(7) J of energy per kg wich is canverted to mechanical energy with x 20 % efficiency rate Take = 9.8 ms^(-2)

Each nuclear fission of uranium nucleus releases _____________ energy. A. 20 MeV B. 235 MeV C. 237 MeV D. 200 MeV
