The Mariana trench is located in the Pacific Ocean at a depth of about 11 000 m below the surface of the water. The density of seawater is1025 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 = 0.0500 m)?
(b) For comparison, determine the weight of a jetliner whose mass is 5.33 Ã- 105 kg.
