James cameron piloted a submersible craft to the bottom of the challenger deep, the deepest point on the ocean's floor, 11,000 m below the surface. what was the total inward force on the 1.1-m-diameter pilot sphere in which cameron sat?

Explanation:

First of all, we need to find the pressure exerted on the sphere, which is given by:

where

is the atmospheric pressure

is the water density

is the gravitational acceleration

is the depth

Substituting,

The radius of the sphere is r = d/2= 1.1 m/2= 0.55 m

So the total area of the sphere is

And so, the inward force exerted on it is

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
