Problem

In glycerin at the surface, the density is

1260\,\mathrm{kg\,m^{-3}}

and the bulk modulus is

4.4\times10^{9}\,\mathrm{Pa}

. At a certain depth the density increases by

2\%

and the bulk modulus increases by

3\%

. Determine, correct to two significant figures, the percentage change in the speed of sound at that depth compared with the surface value.
