What units are used to describe frequency, or vibrations per second?
meters
decibels
pitch
hertz

Answers

Answer 1

Answer:

hertz

Explanation:

Usually frequency is measured in the hertz unit, named in honor of the 19th-century German physicist Heinrich Rudolf Hertz. The hertz measurement, abbreviated Hz, is the number of waves that pass by per second. For example, an "A" note on a violin string vibrates at about 440 Hz (440 vibrations per second).

Read the excerpt from Roll of Thunder, Hear My Cry.

For a long moment no one moved or said a word as Mr. Barnett shone the light directly on T.J., then on R.W. and Melvin, their faces darkened by the stockings. But when Mr. Barnett saw the cabinet lock busted, he flew into frenzied action, hopping madly down the stairs and trying to grab the metal box from Melvin. They struggled, with Mr. Barnett getting the better of Melvin, until R.W. whopped Mr. Barnett solidly on the head from behind with the flat of the axe, and Mr. Barnett slumped into a heap upon the floor as if dead.

Which detail in the excerpt best helps the reader determine the frantic tone?

Answers

Answer: he flew into frenzied action, hopping madly down the stairs

Explanation: I believe this would be the answer because it shows how Mr. Barnett is very frantic. Frenzied means very wild and uncontrolled, which shows that he is doing something quickly. Hopping madly also shows the frantic tone by making it seem like he is in a rush and he is somewhat fazed.

o It gives the reader a visual image of how divided the countries are without having to look on a map

Explanation:

The description and analogy of the country called Pakistan in the text above helps the reader visualize what the country looked like. The use of color descriptors provide imagery that can help any one reading to form mental images of what Pakistan looked like.

Lilia even made it clearer through the comparison of what she saw to two cities in the United States being a single nation separate from the United States. This provides a more concrete understanding of the country known as Pakistan.

English essay about :what goes around comes around​

Answers

Answer:

In our daily life, we would have seen many people being good to us. Being good is a great discipline and learning to be so is wisdom. Only when we realize that by being kind we can reap kindness we can be of great help to our fellow beings.

It does not matter how bad our day would have been; if we decide to be positive we can see positive results for sure. By a small failure if we decide to make our whole mind negative, there are many chances we meet failure in our life.

Also, if only we smile at everyone we can realize the power of being positive. We not stay strong by a smile, but receive the smiles of other people. Learning simple manners that gets us great respect in front of others can make us a person rich of all disciplines. We all know that “Manners Maketh Man”. With good manners and disciplines, we only do good unto others. Hereby, we are entitled as great people in the society.

On the other hand, if we forget discipline we will lose our respect and dignity. If we do not respect other, we will also be treated the same way sooner or later. In order to reach great heights we should walk the path in a good and respectful manner. This ensures we are always honored and received with great respect by everyone.

If we do good, we receive good.

If we do bad, we receive bad.

Simply this means –
