Question

A ball falling in a lake of depth 200m shows 0.1 decrease in its volume

Answer 1

Answer:

The image below depicts a ball at a depth of 200 metres in a tank.

Explanation:

• Here, the depth is 200 metres and the volume drop is 0.1 percent.
• Because p=gh gives the pressure at depth h, where g=9.8ms2 and 103kgm3
• As a result, p=1039.8200 p=19.6105N/m2
• Now, the bulk modulus k=pVV k=19.61050.1100 =1.96109Nm2 is calculated.
• As a result, the bulk modulus of the ball material is 1.96109Nm2.
