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 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 = 0.109 m)? (b) For comparison, determine the weight of a jetliner whose mass is 2.98 x 105 kg.

Answer 1

a= 6190000 N
b= 6313632.7 N
