Question

2) The velocity of sound is proportional to the square root
of molecular weight of the medium.
a) inversely
b) directly. c) doubble
d) half​

Answer 1

Answer:

Correct option is

D

inversely proportional to the square root of

The velocity of sound v in a medium is given by Sir Newton's formula ,

v=

K/ρ

,

where , K= elasticity of medium ,

ρ= density of medium ,

from above formula , we have ,

v=

1/ρ

,

so, velocity of sound is inversely proportional to the square root of density of the medium .
