A centrifuge in a medical laboratory rotates at an angular speed of 3,500 rev/min, clockwise (when viewed from above). When switched off, it rotates through 46.0 revolutions before coming to rest. Assuming it is constant, what is the magnitude of angular acceleration (in rad/s2)?

The magnitude of angular acceleration is .

Explanation:

Given that,

Initial angular velocity,

When it switched off, it comes o rest,

Number of revolution,

We need to find the magnitude of angular acceleration. It can be calculated using third equation of rotational kinematics as :

So, the magnitude of angular acceleration is . Hence, this is the required solution.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
