What force does the water exert on the man?

What force would the water exert on the vehicle's circular observation window, which has a radius of 0.1 m?

• The bottom of the Mariana Trench, located in the Pacific Ocean, is about 11,000 m below the ocean's surface, making it the deepest ocean depth on Earth. If an underwater vehicle were exploring the region, at a depth of 10550 m, -use the density of seawater = 1025 kg/m3 a.) What force would the water exert on the vehicle's circular observation window, which has a radius of 0.1 m? _____N

• Answer:

  Use P = (rho) * g * h P = 1025 kg/m^3 * 9.81 m/s^2 * 10550 m = 1.061 x 10^8 N/m^2 F = PA F = P * (pi * r^2) F = (1.061 x 10^8 N/m^2) * 3.14 * (0.1 m)^2 = 3.33 x 10^6 N
