When a ton of coal burns, it loses 3.3 × 10^-7 kg of mass. The energy given off is

Question

Quizplus · Accepted Answer

The energy given off when mass is lost can be calculated using Einstein's equation, E=mc^2, where m is the mass lost and c is the speed of light (approximately 3.0 × 10^8 m/s). Given the mass loss of 3.3 × 10^-7 kg, the energy released is significantly large, making option D (3.0 × 10^14 J) the correct choice, as it aligns with the expected magnitude of energy release from such a mass loss according to Einstein's theory.
