In one fission of uranium, `3 xx 10^-11 J` of energy is made available. Calculate the number of fissions necessary to generate power of `15 kW`.

Text Solution

Verified by Experts

The correct Answer is:
`5 xx 10^14`
Energy released/fission `= 3 xx 10^-11 J`
Total energy required/second `=15 kW = 15000 W = 15000 J//s`
Number of fissions second `=("total energy"//"second")/("energy"//"fisssion")=(15000J//s)/(3xx10^(-11)J)=5xx10^(14)`
