Assignment 19 1. Explain the difference between rotation, revolution, and precession. 2. A centrifuge is a machine that lets a biologist quickly separate the components of blood into plasma, red blood cells, and platelets. Each component has a different density. Explain how centripetal forces instead of "centrifugal' forces enable biologists to do their tasks. 3. Cylinders A and B have the same mass and radius. But A is hollow, whereas B is uniformly solid. Which cylinder will reach the bottom first? Justify your answer. Figure 21.18
