When an ambulance passes you, the pitch seems to change as it speeds by. This is called the Doppler Effect. Please use complete sentences in your answer.

1-Describe what happens to the sound waves as the ambulance approaches you. How would you hear the sound waves? (2 pts.)

2-Describe what happens to the sound waves as the ambulance moves away from you. How would you hear the sound waves now? (2 pts.)

Answers

Answer 1

Answer & Explanation:

As the ambulance approaches you, the distance between the source of the waves and the observer decreases. As a result, the siren sounds more shrill as the pitch of the wailing siren sounds "higher" than its original value, as sound waves reach you more frequently due to the shorter distance.

The opposite occurs when the ambulance moves away from you. The distance between the ambulance (source of sound waves) and the observer increases. As a result, the siren sounds less shrill and sounds "lower" than its original value since the wave reach you less frequently given the greater distance.

When did Emily Dickinson gain fame for her collection of nearly 1,800 poems?
A. after following the advice of her mentor Thomas Wentworth Higginson
B. after her death, when her sister insisted on publishing the work
C. after attending the excellent Mount Holyoke Female Seminary
D. after sharing her work with her contemporary Walt Whitman

Answers

Answer: B

Explanation:

Most of her works got published after she died and she became well known

The time when Emily Dickinson gained fame for her collection of nearly 1,800 poems is after her death, when her sister insisted on publishing the work. Hence, option B is correct.

What does fame mean ?

Fame seems to come with a lot of rewards, which makes it quite alluring. Everywhere one go once they become renowned, their excellent reputation will follow them, according to the fantasies. Their virtues have been impressively explained in advance, so others will think well of you.

Success is "the favorable consequence of something done," according to the Collins dictionary, whereas fame is "the state of being generally known or recognised; renown; celebrity." Very dissimilar, yet upon closer examination, the definition of success contains a distinct viewpoint: "the accomplishment of wealth, fame, etc."

Emily Dickinson's over 1,800-poem collection first came to public fame after she passed away because her sister insisted on having it published.

Therefore, option B is correct.

Read this passage from “the story of an hour.” why is this passage ironic?
it was her sister josephine who told her, in broken sentences; veiled hints that revealed in half concealing. her husband's friend richards was there, too, near her. it was he who had been in the newspaper office when intelligence of the railroad disaster was received, with brently mallard's name leading the list of "killed." he had only taken the time to assure himself of its truth by a second telegram, and had hastened to forestall any less careful, less tender friend in bearing the sad message.
a.) richards had checked the truth of the news, but it turned out to be wrong.
b.) there was more than one person named brently mallard on the train.
c.) her husband had been traveling by train and there was no railroad disaster.
d.) her sister is the one who tells her, but her sister never liked her husband.

Answers

Answer:

c.) her husband had been traveling by train and there was no railroad disaster

Explanation:

This type of irony is situational irony--  the outcome of the situation is totally different from what people expect. The real outcome is revealed in the ending when Mr. Mallard comes home and causes Mrs. Mallard to die of "heart disease." That itself is also irony (dramatic irony), but it isn't part of the question so I'm not gonna delve into that.

Explanation:

Read the excerpt from "The Role of Social Media in the Arab Uprisings" by Heather Brown, Emily Guskin, and Amy Mitchell.


In July 2012 a report was published by the United States Institute of Peace. . . .


. . . The study suggests that the importance of social media was in communicating to the rest of the world what was happening on the ground during the uprisings. . . .


Data from the Pew Research Center’s Global Attitudes Project at least somewhat supports this conclusion with its findings that the majority of Egyptians are not online. Nearly two-thirds (65%) of the total population do not use the internet. When looking specifically at those with a college education, the use of social media for obtaining political information is more prevalent than in other segments of the population. Though most of the country is disconnected from the internet, 84% of those who are online say they visit social networking sites for news about Egypt’s political situation. These findings point to social media’s important role in spreading information, but do not necessarily indicate that social media was a mobilizing force in the uprisings.


Passing along information is an important part of the news process. Earlier [Project for Excellence in Journalism] research finds the role of Twitter in disseminating breaking news is not limited to the Arab uprisings—the death of Whitney Houston, for example, was announced on Twitter 55 minutes before the [Associated Press] confirming the story.


What types of evidence do the authors use in this excerpt? Select three options.


research related to the popular use of social media in Egypt.

a statistic supporting the claim that social media use in Egypt is not widespread.

testimony about how social media use has changed in Egypt.

an example that compares how traditional media and social media handle a news story.

data related to the decline of social media use after the Arab Spring.

Which two sections of this excerpt from T. S. Eliot's "The Love Song of J. Alfred Prufrock" contain a biblical allusion?
I should have been a pair of ragged claws
Scuttling across the floors of silent seas.
And the afternoon, the evening, sleeps so peacefully!
Smoothed by long fingers,
Asleep … tired … or it malingers,
Stretched on the floor, here beside you and me.
Should I, after tea and cakes and ices,
Have the strength to force the moment to its crisis?
But though I have wept and fasted, wept and prayed,
Though I have seen my head (grown slightly bald) brought in upon a platter,
I am no prophet—and here’s no great matter;
I have seen the moment of my greatness flicker,
And would it have been worth it, after all,
After the cups, the marmalade, the tea,
Among the porcelain, among some talk of you and me,
Would it have been worth while,
To have bitten off the matter with a smile,
To have squeezed the universe into a ball
To roll it toward some overwhelming question,
To say: “I am Lazarus, come from the dead,
Come back to tell you all, I shall tell you all”—
If one, settling a pillow by her head,
Should say: “That is not what I meant at all;
That is not it, at all.”

Answers

Answer:

"Though I have seen my head (grown slightly bald) brought in upon a platter,"

"To say: “I am Lazarus, come from the dead,"

Explanation:

T. S. Eliot's poem "The Love Songs of J. Alfred Prufrock" talks of the alienation of human beings and the despair of the speaker, J. Prufrock. The poem also seems to address an unnamed potential lover that Prufrock seems to have his eyes on.

The two instances of biblical illusions in the given excerpt are in the lines "Though I have seen my head (grown slightly bald) brought in upon a platter," and "To say: "I am Lazarus, come from the dead". These two lines are references to the prophet John whose head was brought on a platter by order of King Herod at the request of Herodias's daughter [Mark 6:14-29]. And the second reference is about Lazarus who was raised from the dead by Jesus [John 11: 38-44].

Answers

Answer:

B). They asked me what I wanted, and I finally said, "I don't know!"

Explanation:

The second option is correctly punctuated as it employs the comma(,), the exclamation mark(!), and the inverted commas("...") aptly. As per the rule, the reported words like 'they asked me what I wanted...said' are not written inside the inverted commas but the exact words "I don't know!" are. The other punctuation marks like a full stop, exclamation marks, etc. are put inside the inverted commas. Thus, option B is the correct answer.

b.
Ask thoughtful questions
c.
Avoid intercultural interactions
d.

Answers

Answer:

I think the answer would be B.) Ask thoughtful questions

Explanation: Which of the following is an example of how to overcome intercultural communication barriers? You could eliminate Assume similarities, Avoid intercultural interactions, and Focus on stereotypes since you want to overcome communication barriers. I'm not sure though that's just the answer i think makes the most sense.

Ask thoughtful questions is an example of how to overcome intercultural communication barriers. Hence, option B is correct.

What is intercultural communication barriers?

In order to overcome these obstacles, which include ethnocentrism, stereotyping, bias, and discrimination, one must first acquire views or judgments about a different culture before any actual dialogue can take place. Effective cross-cultural communication is made more difficult by the attitudes and actions listed below.

Anxiety, presuming similarities rather than differences, ethnocentrism, stereotypes and prejudice, nonverbal misinterpretations, and language issues are the six main obstacles to communication.

Since people from different cultural backgrounds frequently misinterpret each other's meaning, language is a clear barrier to cross-cultural communication. The meanings of body language cues or behaviors vary between cultures even when they share a same language.

Thus, option B is correct.
