In a period of 1.5 s, 5.0 1023 nitrogen molecules strike a wall of area 8.8 cm2.
In a period of 1.5 s, 5.0 1023 nitrogen molecules strike a wall of area 8.8 cm2. if the molecules move at 250 m/s and strike the wall head on in a perfectly elastic collision, find the pressure exerted on the wall. (the mass of one n2 molecule is 4.68 10-26 kg.)
