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...

A stainless steel ball bearing has a radius of 6.35 mm and a denisity of 7.75 g/cm^3. Iron is the principle element in steel while carbon is a minor element. The ball bearing contains 0.25% carbon by mass. Assuming that the percent isotopic abundance for ^13 C is 1.108%, how many iron ^12 C and ^13 C are present in the ball bearing
