A sample of blood is placed in a centrifuge of radius 12.0 cm. The mass of a red blood cell is 3.0 ✕ 10-16 kg, and the magnitude of the force acting on it as it settles out of the plasma is 4.0 ✕ 10-11 N. At how many revolutions per second should the centrifuge be operated?

[4] A centrifuge is used to separate solid blood cells from liquid blood plasma. The solid cells collect on the walls of a chamber of radius re = 8 cm which is spinning 350 times per second. The moment of inertia of the centrifuge (including the blood) is I = 1.2 kg m. (a) What is the normal force exerted by the chamber wall on one gram of blood cells? (b) If the centrifuge is...

A sample of blood in a centrifuge has a centripetal acceleration that is 6.28×103 times as large as the acceleration due to gravity. How many revolutions per minute does the sample make if it is located at a radius of 5.43cm from the axis of rotation? Do not enter unit.

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 2.61 x 103 times as large as the acceleration due to gravity. How many revolutions per...

A disc of mass 290 grams and radius 12.0 cm is rotating about an axis passing through its center at 500 rpm. From a height of 15.0 cm, another disc, of mass 320 grams and radius 12.0 cm is dropped and both discs start to rotate together. The disc which is dropped has some rough padding on it, which creates some frictional torque. (a) Find the angular velocity of the discs as soon as they start to rotate (b) Using...
