Define terminal velocity. Show that the terminal velocity `upsilon` of a sphere of radius r, density `rho` falling vertically through a viscous fluid of density `sigma` and coefficient of viscosity `eta` is given by `upsilon = 2 / 9 ((rho - sigma)r^2 g) / eta` Use this formula to explain the observed rise of air bubbles in a liquid.
