Q. A meat baster consists of a squeeze bulb attached to a plastic tube. While the bulb is squeezed and free, with the open end of the tube under the surface of the basting sauce, the sauce rises in the tube to a distance h, as the Illustrating shows. Using 1.013 × 10^5 Pa for the atmospheric pressure and 1030 kg/m3 for the density of the sauce, conclude the absolute pressure PB in the bulb while the distance h is (a) 0.16 m and (b) 0.13 m.
