An electrical short cuts off all power to a submersible diving vehicle when it is a distance of 29 m below the surface of the ocean. The crew must push out a hatch of area 0.950 m2 and weight 390 N to escape.

If the pressure inside is 1.0atm, what downward force must they exert on the hatch to open it?

277983.465 N

Explanation:

= Density of seawater =

g = Acceleration due to gravity = 9.81 m/s²

h = Depth = 29 m

w = Force = 390 N

A = Area =

Force in the system would be

The downward force must they exert on the hatch to open it is 277983.465 N

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
