A nucleus decays by ${\beta ^ + }$ emission followed by a gamma emission. If the atomic and mass numbers of the parent nucleus are $Z$ and $A$ respectively, the corresponding numbers for the daughter nucleus are respectively.

In a reactor, $2\, kg$ of ${ }_{92} U ^{235}$ fuel is fully used up in $30$ days. The energy released per fission is $200\, MeV.$ Given that the Avogadro number, $N =6.023 \times 10^{26}$ per kilo mole and $1\, eV =1.6 \times 10^{-19}\, J .$ The power output of the eactor is close to$.....MW$
