6.wheel and axle (I think) hope this helps!
Answer:
Yes
Explanation:
Newton's laws states that gravity or force will stop the balls movement. Think of space for a example, if you pushed a soccer ball into space if would float for eternity.
To solve this problem we will use the concepts related to the speed of a string which is given by the applied voltage and the linear mass density of it. With the speed value we can find the fundamental frequency that will serve as a step to find the maximum speed through the relation of Amplitude and Angular Speed. So:

Where,
T = Tension
= Linear mass density


With this value the fundamental frequency would be



Finally the maximum speed is given with the relation between the Amplitude (A) and the Angular frequency, then




Therefore the correct answer is B.
