A nucler reactor delivers a power of `10^(9)` W. What is the amount of fuel consumed by the reactor in one hour?

Options

A. 0.96 gm
B. `0.8` gm
C. `4 xx 10^(-2)` gm
D. `6.6 xx 10^(-5)` gm

Answer

C

Explanation

Power level of reactor , `P = (E)/(Delta t) = (Delta me^(2))/(Delta t)`
mass of the fuel consumed per hour in the reactor , `(Delta m)/(Delta t) = (P)/(c^(2)) = (10^(9))/((3 xx 10^(8))^(2)) = 4 xx 10^(-2)` gm
