An open diving chamber rests on the ocean floor at a water depth of 60 meter. find the air pressure (gage pressure relative to the local atmospheric pressure) in kpa inside of the diving chamber required to keep water from entering the chamber. (assume sg=1.03)

Gauge Pressure required = 606.258 kPa

Explanation:

Water will not enter the chamber if the pressure of air in it equals that of the water which tries to enter it.

Thus at a depth of 60m we have pressure of water equals

Now the gauge pressure is given by

Applying values we get

a and c

explanation:

both a and c are correct answers to my knowledge, it's been a bit since i've done anything related to magnetic fields, but it should be right.

i'm thinking more like energy
