Problem

Glycerine has density

1.26\times10^{3}\,\text{kg\,m}^{-3}

. Its bulk modulus is

4.5\times10^{9}\,\text{Pa}

, while a data sheet lists a “Young’s modulus” of

3.3\times10^{8}\,\text{Pa}

. Determine the speed of sound in glycerine and specify which of the two given moduli you have used.
