A centrifuge is a device in which a small container of material is rotated at a high speed on a circular path. Such a device is used in medical laboratories, for instance, to cause the more dense red blood cells to settle through the less dense blood serum and collect at the bottom of the container. Suppose the centripetal acceleration of the sample is 5.36 x 103 times as large as the acceleration due to gravity. How many revolutions per minute is the sample making, if it is located at a radius of 7.92 cm from the axis of rotation? Number I 287 Units revfminrpm} V To create articial gravity, the space station shown in the drawing is rotating at a rate of 1.20 rpm. The radii of the cylindrical Iy shaped chambers have the ratio rA/rg = 3.00. Each chamber A simulates an acceleration due to gravity of 5.10 misz. Find values for {a} g, {b} r3, and (c) the acceleration due to gravity that is simulated in chamber B
