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 2.10 g to kg gives 0.00210 kg. Plugging into the formula: $E = 0.00210 \, \text{kg} \times (3.00 \times 10^8 \, \text{m/s})^2 = 1.89 \times 10^{14} \, \text{J}$.
