<span>The sentence can be completed as follows:
An example of resonance is when a long, high pitch causes a crystal glass to begin to vibrate and then break.
In fact, the glass has its own frequency of vibration. When there is a sound, normally nothing happens; however, if the frequency of the sound is equal to that of the glass, the glass starts to vibrate and the amplitude of its vibrations increases more and more, until the glass breaks. This phenomenon is called resonance.</span>
Answer:
The more velocity an object has the harder it is to slow it down
Explanation:
slow it down
If we are talking on the force being exerted by a segment of a rope of lenght R on the right on a point M which is being also pulled from the Left by a segment of rope R as shown in the figure attached. Then we invoke Newton's Third Law:
"Any force exerted by an object (in this case a segment of the rope) also suffers a equal and opposite force".
If we pick

whis is the tension exerted by the right segment then the left segment will also exert an equal and opposite force so we have that
