If 'v' is the velocity of sound in a gas , then 'v' is directly proportional to (here M , d and T represents molecular weight of gas , density of gas and its temperature , respectively.)

Options

A. `sqrtM`
B. `(1)/(sqrtd)`
C. `sqrtT`
D. both (b) and (c)

Answer

D

Explanation

If v is the velocity of sound in a gas, then it is directly proportional to the square root of the absolute temperature of gas and inversely proportional to square root of its mass and density .
