Question

multiple choice question
the magnitude of the centripetal acceleration can be found by multiplying the radius of the circle by 4π², then dividing by the square of what quantity of the rotation?
o frequency
o period
o speed
o height

Explanation:

Step1: Recall centripetal acceleration formula

The formula for centripetal acceleration \(a_{c}=\frac{4\pi^{2}r}{T^{2}}\), where \(r\) is the radius of the circular path and \(T\) is the period of rotation.

Step2: Analyze the formula

Comparing with the description in the question (multiplying radius by \(4\pi^{2}\) and then dividing by the square of a quantity), we can see that the quantity is the period \(T\).

Answer:

period
