A scuba diver dives to a depth of 20m in ocean water. If the circular glass plate in the diver's face mask has a diameter of 16cm, what force does the water exert on it?A scuba diver dives to a depth of 20m in ocean water. If the circular glass plate in the diver's face mask ?
Force his face is:


G = m*g


m=density_of_water*V


V=h*S


S=pi*(d/2)^2A scuba diver dives to a depth of 20m in ocean water. If the circular glass plate in the diver's face mask ?
I am probably wrong as I had to convert it all to imperial then back to metric. Math is not a strong point for me so definetly look at other answers as well
