1. Which is the unknown element X participating in the nuclear reaction
Correct Answer: D
2. Giving that for every single fission of Uranium-235 nuclei there is 220 MeV of energy released, calculate the power of nuclear power plant that consumes 192 kg Uranium-235 in a day if the power plant has a 20% efficiency. Take the atomic mass of U-235 equal to 235.04393 u; 1 u = 6605 × 10-27 kg and 1eV = 1.6 × 10-19 J; 1 day = 86400 s.
Correct Answer: A
3. In which of the nuclear reactions below does energy emission (release) /absorption occur?
Correct Answer: B
