`10^(23)` molecules of a gas strike a target of area `1 m^(2)` at angle `45^(@)C` to normal and rebond elastically with speed `1 kms^(1)`. The impulses normal to wall per molecule is " - [Given : mass of molecule = `3.32 xx 10 ^(-27)kg`]

The mass of a hydrogen molecule is 3.32xx10^(-27) kg. If 10^(23) hydrogen molecules strike, per second, a fixed wall of area 2 cm^(2) at an angle of 45^(@) to the normal, and rebound elastically with a speed of 10^(3) m/s, then the pressure on the wall is nearly

A ball of mass 0.1 kg strikes a wall normally with a speed of 30 m s ^( - 1 ) and rebounds with a speed of 20 ms ^( - 1 ) . The impulse of the force exerted by the wall on the ball is

The mass of hydrogen molecule is 3.23 xx 10^(23) hydrogen molecules strike 2 cm^(2) of a wall per second at an angle of 45^(@) with the normal when moving with a speed of 10^(5) cm s^(-1) , what pressure do they exert on the wall ? Assume collision to be elasitc.

The rms speed of the molecules of a gas of density 4 kg m^(-3) and pressure 1.2 xx 10^5 Nm^(-2) is :

The mass of hydrogen molecule is 3.32xx10^(-27) kg. If 10^(23) hydrogen molecules strikes per second at 2 cm^(2) area of a rigid wall at an angle of 45^(@) from the normal and rebound back with a speed of 1000 ms^(-1) , then the pressure exerted on the wall is

The mass of hydrogen molecule is 3.32xx10^(-27) kg. If 10^(23) hydrogen molecules strick per second at 2 cm^(2) area of a rigid wall at an angle of 45^(@) from the normal and rebound back with a speed of 1000 ms^(-1) , then the pressure exerted on the wall is
