Question

In a liquid with density `900 kg//m^(3)`, lonfitudinal waves with frequency `250 H_(Z)` are found to have wavelength `8.0 m`. Calculate the bulk modulus of the liquid.

Answer 1

Correct Answer - A::C
`nu = f lambda = sqrt((B)/(rho))`
`:. B = rho (f lambda)^(2)`
`= (900)(250 xx 8)^(2)`
`= 3.6 xx 10^(9) N//m^(2)`
