Question

Quizplus · Accepted Answer

According to the principle of mass-energy equivalence, when a uranium nucleus undergoes fission, a small amount of mass is converted to energy. Therefore, the mass of the pieces that the nucleus splits into is less than the mass of the original uranium nucleus. This is expressed in Einstein's famous equation E=mc², where E is energy, m is mass, and c is the speed of light.
