cuál es la presión hidrostatica a una profundidad de 1200 bajo el agua? cual es la fuerza ejercida sobre una superficie de 4cm2 situada a esa profundidad?​

Ireally just need to get finished with precal! i’m really sorry i have to do this! hope this !

Scientific classification

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

Iwould have to say sorry i can't elaborate more. hope this though!
