The rate at which velocity changes over time is <em>acceleration</em>.
Answer:
The magnitude of angular acceleration of the motor is
.
Explanation:
Given that,
Initial angular velocity, 
Final angular velocity, 
Angular displacement, 
Let
is the magnitude of the angular acceleration of the motor. It can be calculated using third equation of rotational kinematics as :

So, the magnitude of angular acceleration of the motor is
.
You do not hear it as clearly as you did, the frequency goes down. Likewise, if you moved closer you would hear it more.
A mixture IS NOT a chemical combining of substances. If substances
combine chemically, then they form a compound, not a mixture.
