Physics - Heat & Thermo Question with Solution | TestHub

Nitrogen molecules of mass$4.65\times 10^{-26}$kg strike a wall of area 4$c{m}^2$at the rate of$5\times 10^{22}$per second, moving at 500 m/s at$60^{\circ }$to the normal. Find the pressure on the wall in N/$m^2$(nearest integer). Assume elastic collisions.
