The Mariana trench is located in the Pacific Ocean at a depth of about 11500 m below the surface of the water. The density of seawater is 1025 kg/m3.
(a) If an underwater vehicle were to explore such a depth, what force would the water exert on the vehicle's observation window (radius = 0.10 m)?
(b) For comparison, determine the weight of a jetliner whose mass is 1.1 105 kg.
Pressure = (density) x (acceleration of gravity) x (depth)
Multiply the pressure by the window area to get the force.
The jetliner mass should be written 1.1x10^5 kg
. Multipy that by g for the weight
I appreciate all of your help.
