A sample of blood is put into a centrifuge of radius 15.0 cm. The mass of a red corpuscle is 3.0 x 〖10〗^(-16) kg, make it settle out of the plasma is 4.0 x 〖10〗^(-11) N. At how many revolutions per second should the centrifuge be operated? (Show the computations)

To test the effects of high acceleration on the human body, NASA has constructed a large centrifuge at the Manned Spacecraft Center in Houston. In this device, astronauts are placed in a capsule that moves in a circular path of radius 15 m. If the astronauts in this centrifuge experience a centripetal acceleration 8 times [...]
