Answer to Question #170437 in Mechanics | Relativity for Shalom Anne

Question

Find the speed of sound in water which has a Young's Modulus of 2.1×10^-9 N/m2 at a temperature of 0 and a density of 1000kgm/m3

Answer 1

Answer

The speed of sound in water at 0 ^oC can be calculated as

$v =\sqrt{\frac{ (2.1\times10^{-9} ) }{(1000)}} \\ = 1.45\times10^{-6}m/s$

where

E_v= 2.1$\times10^{-9}$  (N/m²)

and

ρ =1000 (kg/m³)
