The Mariana trench is located in the Pacific Ocean at a depth of about 11,000 meter 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, find what force would the water exert on the vehicle observation window (radius = 0.239 meter)?
(b) For comparison, estimate the weight of a jetliner whose mass is 4.21 x 105 kilogram.
