Problem

Ultrasonic pulses are sent straight down into a water tank. The first echo from the bottom of the tank is received

0.004\,\text{s}

after emission. If the depth of the water is

3.0\,\text{m}

and the density of water is

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

, calculate the bulk modulus of water. a)

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

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

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

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