Answer:

D. vibrate

Explanation:

Energy can be defined as the ability (capacity) to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy, sound energy, etc.

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.

Sound travels faster through solids than it does through either liquids or gases due to the faster vibration of its particles.

Hence, mechanical waves are created when a source of energy causes a medium to vibrate.

Click on the box below to choose the correct sentence pattern for the sentence below.
tester [92]

Answer:

There is good reason to be thankful.

E-V-S (Expletive-Verb-Subject)

Explanation:

Unlike most sentences, this sentence does not follow the usual pattern of Subject + Verb, instead, it begins with an Expletive, then a verb and lastly the subject.

<em>There</em> is the expletive because it is a word without meaning that does not add to the sense of the sentence, and that, instead, is inserted to give emphasis, it acts as an intensifier.

<em>Is</em> is a conjugation of the verb “be” in present and it indicates the existence of the subject.

Lastly, <em>good reason to be thankful</em> is the subject because it is the thing that is being discussed in the sentence.

NARA [144]

Answer: C. Though their personalities were very different, Dickinson and Whitman are both important poets because they captured elements of American life in memorable ways.

Explanation:

This is the most effective comparison-contrast statement because it shows why the two poets should have been different but instead surmounted those differences and had a shared legacy.

It did this by showing that even though both poets had different characters, they managed to capture American lifestyle in a memorable manner even though they would have been expected not to do so seeing as they are similar people.
