Q5. What is the energy released in nuclear fusion primarily due to? (2023)
Solution:
The energy released in nuclear fusion is primarily due to the mass defect, where the mass of the resulting nucleus is less than the sum of the masses of the individual nucleons.

Q9. What is the primary product of the fusion of hydrogen nuclei? (2022)
Solution:
The primary product of the fusion of hydrogen nuclei (protons) is helium, along with the release of energy.
⏱ Time: 0s
Q10. What is the energy released in nuclear fusion compared to nuclear fission? (2023)
Solution:
The energy released in nuclear fusion is generally more than that released in nuclear fission, making it a powerful energy source.
