A barometer has liquid with density 1 Kg/m^3, and the gas has pressure 0.5 atm, what is the height of liquid level?(a) 0.01 atm-m^2-s^2/kg(b) 0.05 atm-m^2-s^2/kg(c) 0.1 atm-m^2-s^2/kg(d) 0.5 atm-m^2-s^2/kg |

Answer» The correct answer is (b) 0.05 atm-m^2-s^2/kg Easy explanation: Pressure of gas + Pressure of Liquid = atmospheric pressure, => 0.5 atm + 1*10*h = 1 atm, => h = 0.05 atm-m^2-s^2/kg. |
