In a period of `1.00 s, 5 xx 10^(23)` nitrogen molecules strike a wall with an area of `8.00 cm^(2)`. Assume the molecules move with a speed of `300 m//s` and strike the wall head-on in elastic collisions. What is the pressure exerted on the wait?
Note : The mass of one `N_(2)` molecules is `4.65 xx 10^(-26) kg`
