Calculate the Q-values of the following fusion reactions:
(a)`1^2H+1^2H rarr 1^3H+1^1H`.
`1^2H+1^2H rarr 2^3(He)+n`
`1^2H+1^3H rarr 2^4(He)+n`.
Atomic masses are `m(1^2H)=2.014102 u`, `m(1^3H)=3.016049 u`, `m(2^3(He))=3.016029 u`, `m(2^4(He))=4.002603 u`.

Answer

A, B, C, D

Explanation

Q-value`=(Deltam)(931.5)MeV`
(a) Q-value `=(2xx2.014102-3.016049-1.007825)xx931.5`
`=4.05 MeV`
Similarly, Q-value of other parts can also be obtained.
