physics help! BEST ANSWER?
when a submarine dives to a depth of 5.0x10 to the power of 2 meters, how much pressure in Pa, must it hull be able to withstand? how many times larger is this pressure than the pressure at the surface? ok the desity of sea water is 1.025x10 to the power of 3
plzz help thank
PLZ EXPLIAN !

Since submarines normally retain atmospheric pressure inside the hull, you can forget about Po and use
Pd = ρ*g*d = 1025*9.8*500 = 5.0225E6 Pa
Standard atmospheric pressure is Patm = 1.01325E5 Pa
Pd/Patm = 49.57
