the deepest point in the sea is 100m below sea level .what arr the water pressure at this depth and the total pressure due to wa
fomenos

The water pressure at this depth and the total pressure due to water and atmosphere are  10.3 x 10⁵ Pa and 11.31× 10⁵ Pa.

<h3>What is pressure?</h3>

The pressure is the amount of force applied per unit area.

Atmospheric pressure, Patm =1.01×10⁵ Pa

Density of water, ρ=1030 kg/m³

Depth, h=100 m

Pressure =ρgh

P = 1030×10×100

P = 10.3 x 10⁵ Pa.

Total pressure, P=Po +ρgh

P=1.01×10⁵ + 1030×10×100

P=11.31× 10⁵ Pa

Hence, total pressure is 11.31× 10⁵ Pa.

garri49 [273]

<u><em>Answer:</em></u>

The answer is 1400 J, according to my Physics teacher.

<u><em>Explanation:</em></u>

You need to take into account everything that is listed in the question; it's important to remember that the question is asking about the change in gravitational potential energy of the object-object-Earth system from 0s to 10s, not 0s to 20s. :)
