From the choices below, select the correct sedimentation velocity, vs, and Brownian velocity, Vs, for a 1500 nm diameter alumina particle with a density of 3,950 kg min water at 25 "C? You may assume the density of water is 1000 kg mos. (a) vs = 57.7 um s" , vs = 166.2 um s- (b) vs = 14.4 um s", V8 = 470.2 um s- (c) vs = 3.607 um s" , vs = 1330 um/s (d) v, = 1.603 um s" , VB = 2443 um s
