1. Centrifuges are commonly used in biological laboratories for the isolation and maintenance of cell preparations. For cell separation, assume centrifugation conditions that are 1.00 x 103 rpm using an 8.31-cm-radius rotor. What is the radial acceleration of material in the centrifuge under these conditions? Express your answer as a multiple of g. Do not enter unit.
3. What is the net force on a virus particle of mass 4.95 x 10-21 kg under the same conditions?
4. To pellet out virus particles and even to separate large molecules such as proteins, super-high-speed centrifuges called ultracentrifuges are used in which the rotor spins in a vacuum to reduce heating due to friction. What is the radial acceleration inside an ultracentrifuge at 75500 rpm with an 8.31-cm rotor? Express your answer as a multiple of g. Do not enter unit.© BrainMass Inc. brainmass.com September 18, 2018, 11:31 am ad1c9bdddf
