______ N

2. Mercury is added to a cylindrical container to a depthdand then the rest of the cylinder is filled with water. If the cylinder is0.4m tall and the absolute (or total) pressure at the bottom is1.3atmospheres, determine the depth of themercury. (Assume the density of mercury to be1.3610⁴kg/m³, and the ambient atmospheric pressure to be 1.013e5 Pa) ___ m

3. The absolute (or total) pressure at the bottom of a cylindrical container with a cross-sectional area of57.0cm²and holding a fluid of density420kg/m³is 115 kPa. For the questions below, assume that the ambient atmospheric pressure is 1.0 atm (1.013e5 Pa).(a) Determine the depth of the fluid. ____ m (b) Determine the absolute pressure at the bottom of the container if an additional1.6010^-3m³of this fluid is added to the container. (Give your answer to at least 3 significant figures.) _____ kPa
