A fusion reaction releases 2.4 × 10¹⁵ J of energy. What mass was converted to energy? (c = 3 × 10⁸ m/s)
Q1. A fusion reaction releases 2.4 × 10¹⁵ J of energy. What mass was converted to energy? (c = 3 × 10⁸ m/s)
Answer: 26.7 g
Explanation: m = E/c² = 2.4 × 10¹⁵ / (9 × 10¹⁶) = 0.0267 kg = 26.7 g. Option B misplaces decimal.
