The ratio of the speed of sound in nitrogen gas to that in helium gas, at 300K is

A

`sqrt((2//7))`

B

`sqrt((1//7))`

C

`(sqrt(3))//5`

D

`(sqrt(6))//5`

Text Solution

Verified by Experts

The correct Answer is:
B
`((C)N_(2))/((C)He) = sqrt((M_(He))/(M_(N_(2)))) = sqrt((4)/(28)) = sqrt((1)/(7))`.
