The energy liberated on complete fission of $1\, kg$ of $_{92}U^{235}$ is (Assume $200\, MeV$ energy is liberated on fission of $1$ nucleus).

Which of the following cylindrical rods will conduct the most heat when their ends are maintained at the same steady temperatures?

If $\frac{x+1}{(2x-1)(3x+1)}=\frac{A}{(2x-1)}+\frac{B}{(3x+1)}$,then $16A+9B$ is equal to

The potential energy of a particle of mass $1\, kg$ in motion along the $x-$axis is given by $U = 4(1 - \cos 2x)$,where $x$ is in $meters$. The period of small oscillation (in $seconds$) is

$N_2$ and $O_2$ are converted into monocations $N_2^+$ and $O_2^+$ respectively. Which statement is wrong?
