Question

an air filled balloon is at a depth of 1 km below the water level in an Ocean determine the normal stress on the balloon if the atmospheric pressure is 10 to the power 5​

Answer 1

Answer:

Below is the detailed answer.

Explanation:

The stress an object can bear according to its area is called normal stress.

We have a balloon at a depth of 1 km below the water level in an ocean. We have to determine the normal stress balloon has if the atmospheric pressure is 10^5.

To determine the normal stress we use the following formula:

Normal stress on the balloon : Normal stress = Atmospheric pressure + hdg

By placing the given values,

= 10^5 + 1000 x 1000 x 9.8

= 9.9x10^6 Pa

The answer of normal stress is 9.9x10^6 per unit area.
