Chapter SH, Problem 10.8APP

To determine

To calculate: Depth of the ocean.

Answer to Problem 10.8APP

Depth of the ocean is $\underset{\_}{1500\text{ m}}$ .

Explanation of Solution

Given:

Time = $2\text{ s}$

Speed = $1500\text{ m/s}$

Formula used:

Speed for an echo is given by,

  $v=\frac{2d}{t}$

where d is distance and tis time.

Calculation:

Depth is calculated as:

  $\begin{array}{l}v=\frac{2d}{t}\\ d=\frac{v\cdot t}{2}\\ d=\frac{\left(1500\text{ m/s}\right)\left(2\text{ s}\right)}{2}\\ d=1500\text{ m}\end{array}$

Conclusion:

Depth of the ocean is $\underset{\_}{1500\text{ m}}$ .
