The Mariana trench is located in the Pacific Ocean at a depth of about 11000m below the surface of the water. The density of seawater is 1025/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 =0.174m )?
(b) For comparison, determine the weight of a jetliner whose mass is 1.89×10⁵.
