An open-tube mercury manometer is used to measure the pressure in an oxygen tank. Part A When the atmospheric pressure is 1040 thbar, what is the absolute pressure (in Pa) in the tank it the height of the mercury in the open tube is \( 25.0 \) cm higher? Part B When the atmospheric pressure is \( 1040 \mathrm{mbar} \), what is the absolute pressure (in Pa) in the tank it the height of the mercury in the open tube is \( 6.5 \) cm lower, than the mercury in the tube connecied to the tank? Express your answer using twe signiticant tigures.
