A vessel contains `6xx 10^(26)` molecules `m ^(-3).` Mass of each molecule is `6xx10^(-27) kg.` Assume that, on an average, one-sixth of the molecules move with a velocity`10^(3)` m/s perpendicularly towards each wall. If the collisions with the walls are perfectly elastic, then which of the following is correct?

A molecule of mass 'm' collide with a wall of container in normal direction with a velocity c. if the collision is perfectly elastic, then the change in momentum of the molcules is

A molecule of mass m moving at a velocity v impinges elastically on the wall at an angle a with the wall. Then

A molecule of mass m moving at a velocity v impinges elastically on the wall at an angle alpha with the wall. Then

IF a gas molecule of a mass m and velocity u collides perpendicularly with a wall of container, what will be the value of momentum of the molecule after the collision?

The mass of a molecule of hydrogen is 3.332xx10^(-27) kg. Find the mass of 1 kg mol of hydrogen gas.

A molecule of mass m moving with a velocity v makes 5 elastic collisions with a wall of the container per second. The change in its momentum per second will be

A cubical container having each sides as l is filled with a gas having N molecules in the container. Mass of each molecule is m . If we assume that at every instant half of the molecules are moving towards the positive x-axis and half of the molecules are moving towards the negative x-axis.Two walls of the container are perpendicular to the x-axis. Find the net force acting on the two walls given? Assume that all the molecules are moving with speed v_(0) .
