Question

Four gas molecules of a gas have speeds 1,2,3,4 km/s. The value of the root-mean square speed of the gas molecules is

Answer 1

Answer:

root of 5

Explanation:

First take the square of the speeds

1^2 is 1

2^2 is 4

3^3 is 9

4^4 is 16

then take the mean of the values 1, 4,9, 6

Mean = (1+4+9+6)/4 = 20/4=5

then take the rootof 5
