A nuclear explosion results in a mass decrease of $2.10 \mathrm {~g}$ How much energy is released during this explosion? (c = 3.00 × 10⁸ m/s)

Question

Quizplus · Accepted Answer

The energy released can be calculated using Einstein's mass-energy equivalence formula $E = mc^2$. Converting mass to kg: $2.10 \, \text{g} = 2.10 \times 10^{-3} \, \text{kg}$. Then, $E = (2.10 \times 10^{-3} \, \text{kg}) \times (3.00 \times 10^8 \, \text{m/s})^2 = 1.89 \times 10^{14} \, \text{J}$.
