Question

nuclear energy uses which of the following processes?
a. gamma radiation
b. fission or fusion
c. chemical reaction
d. electromagnetic impulse

Explanation:

Nuclear energy is harnessed through nuclear reactions. Gamma radiation is a type of radiation emitted during nuclear processes but not the process itself. Chemical reactions involve electron - level changes, not nuclear changes. Electromagnetic impulse is not related to nuclear energy generation. Nuclear fission (splitting of heavy nuclei) and nuclear fusion (combining of light nuclei) are the processes that release large amounts of energy in nuclear reactions.

Answer:

B. Fission or fusion
