A manometer using oil (density 0.9 g/cm3) as a fluid is connected to an air tank. Suddenly the pressure in the tank increases by 0.75 cm of Hg. (a) By how much does the fluid level rise in the side of the manometer that is open to the atmosphere? (b) What would your answer be if the manometer used mercury instead? I'm using 1 Pa for initial pressure and 1.75 Pa for final pressure 1 = .0009kg/cm^3(981 cm/s^2)(d) =>1.1326cm 1.75 = .0009kg/cm^3(981 cm/s^2)(d) =>1.9821cm 1.9821-1.1326 = .8495cm - this is wrong? any ideas why?
