10. Centrifuges are used in biomedical applications. These devices spin at high speeds to separate liquid samples according to density. A test tube of whole blood having a total mass of 25 g is spun at a rate of 6000 rpm to separate the plasma from the platelets. The radius of the rotor and, therefore, the turn is 30.0 cm. a. What is the frequency of the centrifuge? Show your work. To tes b. Determine the centripetal force acting on the test tube. Assume a constant radius. Show your work.
