A meat baster consists of a squeeze bulb attached to a plastic tube. When the bulb is squeezed and released, with the open end of the tube under the surface of the basting sauce, the sauce rises in the tube to a distance h. Using 1.013*10^5 Pa for the atmospheric pressure and 1200 kg/m^3 for the density of the sauce, find the absolute pressure in the bulb when the distance h is a)0.15 m and b)0.10 m
