A stainless steel ball (radius rsphere = 0.3175 cm, density ρsphere = 7.866 g/cm3) falls through a viscous fluid (density ρfluid = 1.2 g/cm3) and quickly reaches terminal speed v. You measure the ball’s position as a function of time to find v. The ball is at positions y = 10 cm at time 2.402 and at position y = 5 cm at time 3.26. Calculate the viscosity η of the fluid in units of poise = g/(cm-s), using your...

Consider a spherical bacterium, with radius 1.7 μm , falling in water at 20° C. Find the terminal speed of the spherical bacterium in meters per second, ignoring the buoyant force on the bacterium and assuming Stokes' law for the viscous force. You will first need to note that the drag force is equal to the weight at terminal velocity. Take the density of the bacterium to be 1.3 × 103 kg/m3. The viscosity of water at 20 °C is...
