Hello , I need this 2 question as soon as possible.. Thank you so much for your help?

1. The Mariana Trench is located in the floor of the Pacific Ocean at a depth of approximately 11,000 m below the surface of the water. The density of seawater is 1025 kg/m'. If an underwater vehicle were to explore such a depth, what force would the water exert on the vehicle's observation window (the circular window has a radius of 0.10 m)? 2. The human lungs can function satisfactorily up to a limit where the pressure difference between the outside and inside of the lungs in one-twentieth of an atmosphere. If a diver uses a snorkel for breathing, how far below the water can they swim? Assume the density of seawater is 1025 kg/ms
