A spherical protein of molar mas 4.5x106g/mol and density 1.33x103kg/m3 is placed in an ultracentrifuge tube filled with water at a distance of 14cm from the rotation axis. The centrifuge then spins at 1.2x103Hz.

a) What is the terminal speed of the protein? (Answer: 7.1x10-5m/s)

b) How long will it take for the protein to sediment a distance of 1.5mm? (Answer: 21s)

A spherical protein molecule has a molar mass of 60,230 g/mol and a density of 1350 kg/ m3. What will its terminal velocity be in water of viscosity 1.0x10-3N/m2 s? How long will it take to fall 1 cm? The time is very long and can be shortened by placing the material in a centrifuge where a very large artificial g can be created.
