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, as the drawing shows. Using 1.013 × 105 Pa for the atmospheric pressure and 1450 kg/m³ for the density of the sauce, find the absolute pressure PB in the bulb when the distance his (a) 0.17 m and (b) 0.11 m. (a) PB = (b) PB = i i
