Imagine that a reactor converts all given mass into energy and that it operates at a power level of 109 watt. The mass of the fuel consumed per hour in the reactor will be : (velocity of light, c is 3×108 m/s)
0.96 gm
0.8 gm
4×10−2 gm
6.6×10−5 gm
As we learnt in
energy mass equivalence -
- wherein
= mass defect
= energy released
Amount of energy produced in
1
This energy is produced by converting mass into energy so
