The Mariana trench is located in the floor of the Pacific Ocean at a depth of about 11400 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)? For comparison, determine the weight of a jetliner whose mass is 1.20 105 kg.
