If `10^(22)` gas molecules each of mass `10^(-26)kg` collide with a surface (perpendicular to it) elastically per second over an area `1m^(2)` with a speed `10^(2)m//s`, the pressure exerted by the gas molecules will be of the order of :
10^(22) particles each of mass 10^(-26) Kg are striking perpendicular on a wall of area 1 m^(2) with speed 10^(4)m//s in 1 sec . The pressure on the well if collision are perfectly elastic is : (A) 2 N//m^(2) (B) 4N//m^(2) (C) 6N//m^(2) (D) 8 N//m^(2)
Five molecules of a gas have speeds 1, 1, 3, 3, 2 km/s the value of the r.m.s spreed of the gas molecules is
10^(23) molecules of a gas, each having a mass of 3xx10^(-27) kg strike per second per sq. cm. of a rigid will at an angle of 60^(@) with the normal and rebound with a velocity of 500m//s . What is the pressure exerted by the gas molecules on the wall?
A box of mass 10 kg has a base area of 1m^(2) . What is the pressure exerted by it on the ground? (Take 1kg wt=10N)
