To calculate work done on an object, a. multiply the force in the direction of motion by the distance the object moved b. multiply all forces applied to the object by the distance the object moved c. divide the force in the direction of motion by the distance the object moved d. divide the distance the object moved by the force in the direction of motion

P=16021.9psi

Explanation:

pressure is defined as the amount of force exerted on an area,

to find the absolute pressure at the bottom of the sea we must add the pressure due to the water which is given by the equation  ρgh, and add it with the atmospheric pressure

P=Patm+Pw

P=total presure at the bottom of the sea

Patm=  atmospheric pressure=14.7psi

Pw=pressure due the weight of water=ρgh

ρ=density=64.2 lb/ft3=2slug/ft3

g=gravity=32.1 ft/s2

h=depth=6.8miles=35904feets

Solving PW

Pw=(2)(32.1)(35904)=2305036.8Lbf/ft^2=160007.2lbf/in^2

using initial ecuation

p=Pw+Patm=160007.2+14.7

P=16021.9psi
