The fraction of gaseous molecules having...

The fraction of gaseous molecules having speed in between u and u+ du as governed by Maxwell distribution of speeds is given by `(dN_(u))/(N) = 4pi ((M)/(2pi RT))^(1//2)` exp `(-"Mu"^(2)//2 RT) u^(2)` du
Graphically this distribution is shown in fig.

Based on this distribution, answer the following three question
