Answer 2

The speed of sound in water is 1449.13 m/s.

Explanation:

Given that,

The bulk modulus of water, $B=2100\ MPa=2100\times 10^6\ Pa$

We need to find the speed of sound in water. The speed of sound in terms of Bulk modulus is given by :

$v=\sqrt{\dfrac{B}{\rho}}$

$\rho$ is the density of water

$\rho=1000\ kg/m^3$

$v=\sqrt{\dfrac{2100\times 10^6\ Pa}{1000\ kg/m^3}}$

v = 1449.13 m/s

So, the speed of sound in water is 1449.13 m/s. Hence, this is the required solution.
