Answer:
I think it's A is the answer
Answer:
it is the first answer
Step-by-step explanation:
The disk spins at a constant number of revolutions per second. This means, the angular velocity is constant.
We know that,
Linear velocity = r x Angular Velocity
where r is the radius.
So, for a given angular velocity, larger value of r will have larger Linear velocity. Since the value of r at point B is more than at point A, the value of Linear velocity will be more at point B.
So, the correct answer is option C
An inch = 2.54 Centimeters. So take 34.5 × 2.54 and you will get 87.63 centimeters.
