To dive far below the surface of the water, a submarine must be able to withstand enormous pressures. At a depth of 351 m, what pressure does water exert on the submarine’s hull? Use g=9.81 m/s2.

P=3647934.3 Pa

Explanation:

We use the formula for pressure inside a fluid:

Where is the pressure at its surface (the atmospheric pressure in our case), its density (the density of seawater in our case), g the acceleration of gravity (which is given in our case, and known) and h the depth at which we want to know the pressure (which is given in our case). For our case then we have:

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

cant without the picture! ?
