9:. What is the absolute pressure at :1 depth of 9.03 m below the surface of :1 deep lake? Assume atmospheric pressure miller" Lea\" cl: -= -ac is 1.01 x 105 Pa. absolute pressure: 1.95 x105 Incorrect Pa A student in an undergraduate physics lab is studying Archimede's principle of bouyancy. The student is given a brass cylinder and, using a triple beam balance, nds the mass to be 3.21 kg. The density of this particular alloy of brass is 8.?4 gfcmg. The student ties a massless string to one end of the cylinder and submerges it into a tank of water where there is an apparent reduction in the weight of the cylinder. With this information, calculate the volume, V, of the cylinder and the tension, T, in the string when it is submerged in the tank of water. The density of water is LOO gfcm3, and the acceleration due to gravity is g = 9.8] W52. Water, with a density of p = 1185 kg/m', flows in a horizontal pipe. In one segment of the pipe, the flow speed is v1 = 7.33 m/s. In a second segment, the flow speed is v2 = 1.77 m/s. What is the difference between the pressure in the second segment ( P2) and the pressure in the first segment (P,)? P2 - P1 = PaA thin stream of water flows smoothly from a faucet and falls straight down. At one point, the water is flowing at a speed of v1 = 1.71 m/s. At a lower point, the diameter of the stream has decreased by a factor of 0.751. What is the vertical distance h between these two points? h = cmA liquid of density 125% kgi'lm3 flows steadily through a pipe of varying diameter and height. At Location 1 along the pipe. the ow speed is 9.95 mfs and the pipe diameter d. is 12.3 cm. At Location 2, the pipe diameter d; is 14.7 cm. At Location 1. the pipe is Ely = 9.5? In higher than it is at Location 2. Ignoring viscosity. calculate the difference P between the uid pressure at Location 2 and the uid pressure at Location 1. Location 1 Lccuu'un 2
