How much energy is released in a nuclear reactor if the total mass of the fuel decreases by $1.0 \mathrm{~g}$ ?
A) $9.0 \times 1013 \mathrm{~J}$
B) $3.0 \times 1011 \mathrm{~J}$
C) $3.0 \times 1014 \mathrm{~J}$
D) $9.0 \times 1014 \mathrm{~J}$

Quizplus · Accepted Answer

The energy released can be calculated using Einstein's equation $E=mc^2$, where $m$ is the mass loss (1.0 g = 0.001 kg) and $c$ is the speed of light ($3.0 \times 10^8 \, \text{m/s}$). Plugging in the values, $E = 0.001 \, \text{kg} \times (3.0 \times 10^8 \, \text{m/s})^2 = 9.0 \times 10^{13} \, \text{J}$.
