Question 8

Which of the following statements best describes the difference between nuclear fission and nuclear fusion?

Accepted Answer

A. Nuclear fission involves the splitting of a heavy nucleus, while fusion combines light nuclei to form a heavier nucleus. — Nuclear fission is the process where a heavy nucleus (like uranium-235) splits into smaller nuclei, releasing energy. Nuclear fusion, in contrast, involves combining light nuclei (like hydrogen isotopes) to form a heavier nucleus, which is the process powering stars. Option A correctly captures this distinction. Option B is incorrect because fusion releases significantly more energy per unit mass than fission. Option C is partially correct but oversimplifies fission, which also requires overcoming binding energy barriers. Option D is misleading as it conflates the energy release aspect with th

Answer

Answer

C. Enforce rules strictly from the first day without explaining their purpose.

Answer
