It put __B-- is that correct??
The objects that produce large amplitude waves are Stars, Large machines, Rocks falling from the mountain, Earthquakes, Volcanoes
The objects producing small amplitude waves include ping-pong ball, Tuning fork, stones, Speakers, Spring
<u>Explanation</u>:
The wave's amplitude is characterised by the ultimate displacement of an object from its median position. Generally, wave with high energy (or the waves emanating from big bodies or high energy bodies) are high amplitude waves. Since the body has a high amount of energy, it produces a comparatively large amount of displacement of the particle. hence the high amplitude.
Similarly, small bodies or bodies with less energy produces a low amplitude wave. This also can be understood in terms of displacement of the particle from its mean position.

Answer:
This paragraph lacks variety, because each sentence begins with the subject, Cory.
The first two lines in this excerpt from "A Grain of Sand" by Frances Ellen Watkins indicate its subject, which is the very grain of sand. In the first line it is mentioned explicitly, whereas in the second one it is replaced with the third person singular pronoun <em>it</em>: "Do you know to me it (the grain of sand) brought just a simple loving thought?". It is a quite common resource for authors, since the use of pronouns prevent poems, as well as other kinds of literary and non-literary works, from being repetitive, that is, pronouns help authors avoid using the same word or term over and over again.
