At a depth of 1000 m in an ocean (a) what is the absolute pressure? (b) what is the auge pressure? (c ) Find the force acting on the windown of area `20 cm xx 20cm` of a submarine at this depth, the interior of which is maintained at sea-level atmospheric pressure. The density of sea water is `1.03 xx 10^(3) kg m^(-3)`, `g=10ms^(-2)`. Atmospheric pressure = `1.01 xx 10^(5) Pa`.
