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 x 105 Pa for the atmospheric pressure and 1160 kg/m for the density of the sauce, find the absolute pressure Pp in the bulb when the distance h is (a) 0.16 m and (b) 0.12 m. (a) PB= i (b) PB = iA mercury barometer reads 735.0 mm on the roof of a building and 760.0 mm on the ground. Assuming a constant value of 1.29 kg/m for the density of air, determine the height of the building
