In a period of 1.0 s, 5.0 x 1023 nitrogen molecules strike a wall of area 8.0 cm2. If the molecules move at 3.00 x 102 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 x 10-26 kg.)

Step 1

Given,

Step 2

Since the collision of molecule is perfectly elastic collision so velocity will be remain same even after collision but direction will change. Force can be calculated using Newton’s Second law,

Step 3

By plugging in the given values to...
