The movement of a sphere in a liquid a hollow steel sphere with a mass of 0.100 g and a diameter of 4 mm is a liquid the column is being left inside. The sphere is reaching a terminal velocity of 1.5 cm/s. The density of the liquid is 1.2 g/cm3 and o the gravitational acceleration on the ground is 981 cm/s2, the sphere is far enough away from the walls of the container, the wall effects negligible. a)(10p). Calculate the drag coefficient. b)(10p). Find the drag force as dyn. c)(5p). Calculate the Viscosity of the liquid.
