Aspherical protein of molar mass 4.5x100 g/mol and density 1.33x10 kg/m3 is placed at the top of a 2-cm-long centrifuge tube filled with a fluid of density 1.1x103 kg/m3 and viscosity of 1.8x10 pa-s. in the centrifuge, the sample is placed at a distance 20 cm from the rotation axis, and the centrifuge is then run at 3000 revolutions per second (i. e. 3000 hz). a) what is the diameter of these proteins? b) what is the terminal speed of these proteins under centrifugation? c) approximately how long will it take the proteins to sediment to the bottom of the tube?
