Please i need the answers of parts c and d and thank you Fourth eyerqise: Pressure in a manometrie tube (3 pts) The aim of this exercise is to find the pressure of air confined in a manometric tube The manometric tube has one end open to air. We pour mercury of density phg 13600kg/m3, into the tube until a variation in the levels happens; This variation is BC 30cm in this experiment. The atmospheric pressure is 760mm Mg. The gravitational field strength is 10N/kg. a. b. d. Determine the atmospheric pressure in Pascal. Determine the total pressure exerted on level B. The pressure on level B is equal to the pressure on level A; justify this statement. Deduce PA, the pressure of the confined air on level A. confined gas 30 cm - -13.
