The ratio of root mean square velocity of hydrogen at $50 \, K$ to that of nitrogen at $500 \, K$ is closest to

If the average velocity of $N_2$ gas at $27 \, ^oC$ is $0.3 \, m/sec$,then at what temperature in $K$ will the average velocity be $0.6 \, m/sec$?

What is the relationship between the average velocity $(v)$,root mean square velocity $(u)$,and most probable velocity $(\alpha)$?

The ratio of most probable velocity to that of average velocity is
