Question

The speed of sound in a medium depends on(a) the elastic property but not on the inertia property(b) the inertia property but not on the elastic property(c) the elastic property as well as the inertia property(d) neither the elastic property nor the inertia property

Answer 1

A) the elastic property but not on the inertia property

Answer 2

Answer:

(b) the inertia property but not on the elastic property

Explanation:

The speed of the sound in a fluid is described as -  V = √(B/ρ)

The speed of sound in a longitudinal solid rod is described as -V = √(Y/ρ)

Thus, for most of the extended solids, V is a complicated function of B as well as G according to the Shear Modulus. B, Y and G all represent as the measures of elastic properties and ρ is the measure of the inertia property. Hence the speed of sound in a medium depends on both the elastic as well as the inertia property.
