Question

10. A person is diving in a lake in the depth of h=10.5 m. The density of the water is q= 0 x 10³kg/m³. The pressure of the atmosphere is P0= 0 x 10⁵Pa. The surface area of the top of the person’s head is A=0.0335 m².

1. Express the absolute pressure at the depth of h, P, in terms of p0, q, and h.
2. Calculate the numerical value of P in Pa.
3. Express the magnitude of the force exerted by water on the top of the person’s head F at the depth h in terms of P and A.
4. Calculate the numerical value of F in N.
