{"knowledge_schema": {"broad_category": "Physics \u2192 Nuclear Physics \u2192 Fission", "refinement": "This problem involves the conservation of energy and mass in the context of nuclear reactions, specifically spontaneous fission.", "specific_scope": "The focus is on calculating the energy released during the fission of a nucleus, given the rest-mass energy of the original nucleus and the mass relationship between the resulting fragments.", "goal": "Determine the energy released during the fission process by comparing the rest-mass energy of the original nucleus with the combined rest-mass energy of the fragments."}, "summary": "This problem is rooted in nuclear physics, specifically the process of fission, where a nucleus splits into smaller fragments. The task involves applying the principles of conservation of energy and mass to calculate the energy released during this process. Given the rest-mass energy of the original nucleus and the mass relationship between the resulting fragments, the goal is to find the difference in energy, which represents the energy released during fission. The answer to the problem is 5 MeV, indicating the energy released in the reaction."}
