Explanation / Answer

We Know that :       Pressure = density of thesubstance x acceleration due to gravity x height of the columnraised.          Given :              Pressure of the mercury = pressure of water               13.6 g / ml x 980 cm / s2 x 76 cm = 1 g / ml x 980 cm /s2 x h ( cm )                   height of the water column raised = 1033.6 cm                                                                        = 1.0336 m    (b)             Pressure = density of the substance x acceleration due to gravity xheight of the column raised                            = 1000 Kg / m3 x 9.8 m / s2 x 9.7536m                             = 95585.28 atm       The total pressure = pressure exerted by the body of the diver +pressure at the surface of the earth                                     = 95586.22 atm.
