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...

Such a device is a 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 6.60x10^3 times as large as the acceleration due to gravity. How many revolutions per minute is...

Steve was subjected to accelerations in a horizontal "centrifuge". It is considered that such a device has a radius of 5.0 m and can generate a centripetal acceleration equivalent to 7 times the average gravitational acceleration on Earth. a) For this maximum acceleration, what is the modulus of the astronaut's speed along the circular path? b) At how many revolutions per minute should the rotation occur to achieve such acceleration? c) What is the period of this rotation?
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? rev/s A sample of blood is placed in a centrifuge of radius 12.0 cm. The mass of a red blood cell is 3.0 x...

A centrifuge takes 100.0s to spin up from rest to it's final angular speed with constant acceleration. A point is located 10.0cm from the axis of rotation of the centrifuge moves with a speed of 250.0m/s when the centrifuge is at full speed. (a) What is the final angular speed? (b) What is the average angular acceleration of the centrifuge as it spins up? (c) How many revolutions does the centrifuge make as it goes from rest to it's final...
