Question

Quizplus · Accepted Answer

The energy-matter equivalence is given by Einstein's equation, E=mc^2, where E is energy, m is mass, and c is the speed of light. The energy released in the nuclear reaction is 1.8×10^14 Joules. To find the mass lost, we rearrange the equation to m=E/c^2. Given that c^2 is approximately 9×10^16 m^2/s^2, the mass lost is 1.8×10^14 J / (9×10^16 m^2/s^2) = 2.0×10^-3 kg.
