The velocity of sound in alcohol is 1300 m/s and the density of alcohol is 0.08 `g//cm^(3)`. The bulk modulus of alcohol is

Options

A. `0.65 xx 10^(-3) N//M^(2)`
B. `1.35 xx 10^(3) N//m^(2)`
C. `0.65 xx 10^(6) N//m^(2)`
D. `1.35 xx 10^(8) N//m^(2)`

Answer

D

Explanation

`v = sqrt((k)/(rho)) :. V^(2) = (k)/(rho)`
`:. k = rhov^(2) = 0.08 xx 10^(+3) xx 1300 xx 1300`
`= 1.35 xx 10^(8) N//m^(2)`
