1x9x10^16 Joules of energy which is very high quantity

Answer 6

1 kg*, not 1 km :-P

Answer 7

\[m c ^{2}= E\]
Where, E is energy, m is mass of the body and c is the velocity of light
Albert Einstein had developed this formula.

Answer 8

it was actually a formula that was obtained by some helper...
