The items related to nuclear fission reactions are:
B. Used in the Fat Man and Little Boy nuclear bombs C. Used in nuclear power plants E. Involved in chain reactions
Here's a brief explanation of each:
- A. Occurs in the sun: This is incorrect as the sun primarily produces energy through nuclear fusion, not fission.
- B. Used in the Fat Man and Little Boy nuclear bombs: This is correct; both bombs utilized nuclear fission (U-235 in Little Boy and Pu-239 in Fat Man).
- C. Used in nuclear power plants: This is correct; nuclear fission is the process used to generate energy in nuclear power plants.
- D. No radioactive waste is produced: This is incorrect; nuclear fission reactions do produce radioactive waste.
- E. Involved in chain reactions: This is correct; fission can produce a chain reaction, where one fission event causes further fission events.
So, the correct answers are B, C, and E.
