Answer 2

Answer:

3)mnv^2/3l^3

Explanation:

The momentum imparted per unit time to the vessel by the molecule

∆F=n∆p

so change in momentum ∆p=2mv

And molecules collide from 2 surfaces of the vessel s0ototal time ∆t=2l/v

Therefore number of collision per unit time n=1/∆t=v/2l

F=mv^2/l

For a cube all the direction are equal

F=mnv^2/3ln

Therefore P=F/l^2

P=mnv^2/3l^3
