A glass tube of cross-sectional area 0.00013 m is partially filled with water. An oil with a density of 790 kg/m is slowly poured into the tube so that it does not mix with the water and floats on top of it. The height of the oil above the water's surface is 3 cm. (a) By how much does the pressure change at a depth of 10 cm below the water's surface after the oil is added? (On the side where the oil is sitting)? (b) Would the pressure at this depth (1) increase or (2) decrease if you added more oil to the tube? (input either 1 or 2 into the answer box) A glass tube of cross-sectional area 0.00013 m is partially filled with water.
