Medical centrifuge. Medical technicians use small centrifuges to isolate blood cells. A typical unit holds six test tubes, rotates at 3420 revolutions per minute, and produces a centripetal acceleration of 1560. How far are the test tubes from the rotation axis? Medical centrifuge. Medical technicians use small centrifuges to isolate blood cells. A typical unit holds six test tubes, rotates at 3420 revolutions per minute, and produces a centripetal acceleration of 1560. How far are the test tubes from the rotation axis?Explanation / Answer
angular speed w = 3420 rpm = 3420 * 2*pi rad / 60 s = 358.14 rad / s centripetal acclerationa a= 1560 m / s^ 2 we know a = rw^ 2 from this distance of the test tubes r = a / w^ 2 = 0.01216 m = 1.216 cm
