Explanation:
Potential energy = mass x gravity x height
P.E = 4 x 9.8 x 3
P.E = 117.6 J
The pressure of the water on the diver is given in an expression written as:
<span>p=15+15/33d
where p is the pressure and d is the distance of the diver </span><span>below the surface.
The pressure is calculated as follows:
</span>p=15+15/33(100) = 15.00 pounds per square feet
Therefore, the correct answer is option A.
