`N (lt 100)` molecules of a gas have velocities 1,2,3….N km/s respectively. Then

N( lt 100) molecules of a gas have velociteis 1,2,3……N km/s respectively.Then

Three molecules of gas have their velocities 1,2,3, kms^(-1) respectively. Calculate their average and r.m.s speeds.

N molecules of a gas have speeds 1,2,3....Nm/s respectively.The ratio of rms speed to average speed is

Four molecules of a gas have velocity 2, 4, 6 and 8 kms^(-1) , respectively. The ratio of their root mean velocity and average speed is :

Four molecules of a gas have velocity 2, 4, 6 and 8 kms^(-1) , respectively. The ratio of their root mean velocity and average speed is :

Four molecules of a gas have speed 1, 2, 3 and 4 km s^(-1) respectively. The value of rms speed of the molecules is (in km s^(-1) )
