Calculate the fraction of `N_(2)` molecules at 101.325 kPa and 300K whose speeds are in the range of `u_(mp)- 0.005 u_("mp")` to `u(mp)+ 0.005u_(mp)`

Arrange in increasing order to U_(av) U_(mp) and U_(rms) .

The ratio between the three speeds, u_(mp) : u_(av) : u_(rms) is given as

Calculate the binding energy for nucleon of . _6^(12) C nucleus, if mass of proton m_p = 10078 u , mass of neutron m_n = 1.0087 u , mass of C_12, m_C =12.0000 u , and 1 u =931 .4 MeV .
