Question

In a solid, the speed of elastic longitudinal wave is 1.35ms -1. If the Young’s modulus of
elasticity of the solid is 2X1011 N m-2 calculate its mass density.

Answer 1

ρ=E / V^2

ρ= (2⋅〖10〗^11)/〖1.35〗^2 =1.097 〖10〗^11 kg/m^3

Answer: ρ=1.097 〖10〗^11 kg/m^3

The wrong problem statement.
