Question

multiple choice 1 point which describes the differences between nuclear fission and nuclear fusion? nuclear fission produces energy in nuclear power plants, and nuclear fusion produces the energy in the core of the earth. nuclear fission splits a heavier nucleus into smaller nuclei, and nuclear fusion is the process that produces the radiant energy of stars nuclear fission produces the energy in the core of the earth, and nuclear fusion produces energy in nuclear power plants nuclear fission is the process that produces the radiant energy of stars, and nuclear fusion splits a heavier nucleus into smaller nuclei.

Explanation:

To determine the correct option, we analyze the definitions of nuclear fission and fusion:

• Nuclear fission: Splits a heavy nucleus into smaller nuclei, used in nuclear power plants to produce energy.
• Nuclear fusion: Combines light nuclei to form a heavier nucleus, occurs in stars (like the Sun) to produce radiant energy, and also in the Earth's core (though the main energy source of the Earth's core is radioactive decay, but fusion concepts relate to star energy).

Now, let's evaluate each option:

• Option 1: Incorrect. Nuclear fission is for power plants, fusion for stars (not Earth's core energy mainly from fission - related decay).
• Option 2: Correct. Fission splits heavy nuclei, fusion produces star energy (fusion in stars combines nuclei to release energy).
• Option 3: Incorrect. Earth's core energy is from radioactive decay (fission - like processes), and power plants use fission, not fusion.
• Option 4: Incorrect. Fusion produces star energy (combines nuclei), fission splits heavy nuclei.

Answer:

The second option (the one stating "Nuclear fission splits a heavier nucleus into smaller nuclei, and nuclear fusion is the process that produces the radiant energy of stars")
