Problem

Answer the following. (1) In a liquid with density

1300\,\text{kg m}^{-3}

, longitudinal waves with frequency

400\,\text{Hz}

are found to have wavelength

8.00\,\text{m}

. Calculate the bulk modulus of the liquid. (2) A metal bar with a length of

1.50\,\text{m}

has density

6400\,\text{kg m}^{-3}

. Longitudinal sound waves take

3.90\times10^{-4}\,\text{s}

to travel from one end of the bar to the other. What is Young's modulus for this metal?
