Stokes' Law describes sedimentation of particles in liquids and can be used to measure viscosity. Particles in liquids achieve terminal velocity quickly. One can measure the time it takes for a particle to fall a certain distance and then use Stokes' Law to calculate the viscosity of the fluid. Suppose a steel ball bearing (density 7.8x103 kg/m3, diameter 3.0 mm) is dropped in a container of motor oil. It takes 12 s to fall a distance of 0.60 m. Calculate the viscosity in kilograms per meter per second. Group of answer choices 0.74 0.75 0.76 0.77
