Problem 2 [Centrifuging samples) A lab technician is centrifuging a blood sample at a rotation rate of 3 x 103 rpm (revolutions per minute}. The radius of the circular path followed by the sample is 0.15 m. A. Determine the linear speed of a blood cell in the sample. Give your answer in m/s. B. What is the magnitude of the centripetal acceleration on the blood cell? C. Consider a blood cell in motion in the middle of the sample with a higher density than the fluid around it. What force (or forces) is responsible for providing the centripetal acceleration on a blood cell? . The force of gravity . The drag force a b c The buoyant force d. The normal force from the walls of the centrifuge test-tube e (a) and {c} f (bl and (c) g (cl and [d]
