प्रश्न
What do you mean by nuclear energy? What is responsible for its release?
उत्तर
Energy released by the combining of nuclei of an atom or by the decay of an unstable radioactive nucleus during a nuclear reaction, i.e., during fusion or fission, is known as nuclear energy. Mass defects, also referred to as loss of mass, are what produce nuclear energy.
