Answer:

You have to calculate

Explanation:

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work.

A diver who is 10.0 m underwater experiences a pressure of 202 kPa. If the diver's surface area is 1.50 m.sq, with how much tota

Deffense [45]

The pressure on the diver is given by:

$p=\frac{F}{A}$

where F is the force exerted by the water on the diver, while A is the area of the diver.

In this problem, we know the pressure: $p=202 kPa=2.02 \cdot 10^5 Pa$ , and the area of the diver, $A=1.50 m^2$ , therefore we can rearrange the initial equation to find the force on the diver:
