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 = 0.201 m)? (b) For comparison, determine the weight of a jetliner whose mass is 3.38 x 105 kg.

• physics -

Multiply the window area (in m^2) by the pressure (in Pascals), which is (density)*g*(depth).
That will give you the window force in Newtons.

For the airplane weight, use M*g

Two can play this passive agressive thing coward. Aint the info age grand.
