How is a radar gun able to calculate the speed of a moving object using radio waves?

Answers

Answer 1

Answer:

B. Radio waves are reflected off of the moving object, which causes a change in frequency that can be analyzed by the software of the radar gun to calculate the object's speed.

Explanation:

close

As an object moves away from a radar gun, each successive wave is reflected off of the object onto the radar gun at a position farther than the previous wave. As a result, the distance between two successive crests increases and the frequency of the reflected wave decreases. Similarly, when an object moves toward a radar gun, each successive wave is reflected back to the radar gun at a position closer than the previous wave. As a result, the distance between two successive crests decreases and the frequency of the reflected wave increases. A decrease or increase in frequency is analyzed by a software program in radar guns to determine the speed of the object.

Therefore, radio waves are reflected off of the moving object, which causes a change in frequency that can be analyzed by the software of the radar gun to calculate the object's speed.

This is a question for Gulliver's Travels Part 1: A Voyage to Lilliput Could any part of Swift's text be applied to the two major political parties in this country? Explain.

Answers

The correct answer to this open question is the following.

A Voyage to Lilliput. Could any part of Swift's text be applied to the two major political parties in this country.

Yes, of course, it can be applied to the United States political parties.

On one hand, there is the Republican Party, whose members are conservative people who support nationalistic ideas, they are religious people with traditional approaches to family values, do not like the government to raise taxes to pay for social programs, and they support more investment in weapons and defense.

On the other hand, there is the Democratic Party. A more liberal party whose ideas tend to support the increase in taxes to create social programs to help the ones in need, they are more open to supporting minority groups, and liberal ideas about sexual orientation.

Both parties spend much of the time arguing, accusing each other, finger-pointing and insulting, instead of working together for the benefit of the country.

Answers

In my opinion people exclude others for many reason and some may include jealousy. I think this is very noticeable especially in groups of students. They tend to exclude even their own friends sometimes, and I personally don’t think if a friends is excluding you that they should still be called your friend. People get excluded when someone else doesn’t like them or wants to take the spotlight for themselves. This could be for many reasons inclusions self insecurity or just to be plain mean. It all depends on the situation. But people ostracize others to have more themselves so envy or greed but also because they want to hurt others on purpose

George shoots Lennie. Was George’s decision an act of love or selfishness? Why?

Answers

Answer:

Selfishness

Explanation:

There is no excuse to shoot someone

Answer: I think he didn't do the right thing because well i  mean, George did not do the right thing at the end of the book because I believe Lennie still had a reason for living and that should not have been taken away from him. There were plenty of other solutions to Lennie's problem than killing him. I also think that George should not have given up on his and Lennie's dream, I think it was 100% possible, if George had allowed it to be.

Explanation:

I hope this helps. I really think he shot him in love though because he didn't want lennie to be tourched in a room full of special kids and George knew how much Lennie was a danger to people so he just shot him, but I still don't think it was right for George to shoot him..

Wyatt Earp was a famous gunfighter in the American West. Born in 1848, Earp held several jobs before becoming
an admired, and feared, gunslinger. He was a stagecoach driver, railroad worker, and buffalo hunter. He was also
a bit of a gambler. Earp's reputation as a fearless, righteous sheriff grew when he turned Dodge City, Kansas,
from a lawless town into a peaceful city. From there he moved on to Tombstone, Arizona, joined by his brothers
and his good friend Doc Holliday. There, Earp and his crew fought in the now legendary gunfight at the O.K.
Corral. Many books have been written, and films made, about this famous battle between the law-abiding Earp
brothers and the criminal Clanton family.

B

С

D

Answers

Answer:

B). Combating

Explanation:

The most appropriate adjective to define Earp's qualities would be 'combating' as he is popularly known as the fearless lawman who was righteous in his conduct. This attitude and his efforts helped in transforming the lawless town of Kansas into a peaceful city. Infact, he died also during a gunfight with O.K.  Corral. Although he got arrested several times due to his association with brothels but he never attempted to jump off the jail and later he became a police officer. Probably, this is why he is known as a lawman and a gunslinger too. Thus, option B is the correct answer.

C- attach reflectors to tires and seat.

Explanation:

A 3-column table with 1 row titled Bicycle Safety. Column 1 is labeled Helmet with entry Confirm proper sizing. Column 2 is labeled Tires with entry Check tread and inflation. Column 3 is labeled Visibility with no entry.

From the above question, Option C is the best that completes the chart. This chart shows steps to Bicycle Safety. Attaching reflectors to tires and seat will help assure safety especially when riding in the night. Reflectors are shiny and when light hits them, they reflect the light. This helps other cyclists and motorists to know that a rider is in front.

Explanation:

"The Story of My Life" by Helen Keller is a memoir where the blind and deaf author talks about her childhood and how she came to overcome her physical disabilities. The book provides an inspiring insight into the struggle of Keller and how she came to embrace life without the necessary sight and sound.

It was at this moment that she knew and realized the potential she has, the barriers she can overcome, and enjoy life like other people, even though through a much different aspect.

Thus, the correct answer is that she learned she could overcome the obstacles in her life.

What is the one method you most often use to manage stress?

Answers

I am someone with anxiety, so I will say what I do, I hold my breath for 10 seconds, breath out for five seconds, hold breath for another 5 seconds, then breath in for 5 seconds. You can just start counting, focus on your breathing, do yoga, try to avoid doing stressing things, and read a book or try to rest for a bit

Answer:

One method I personally most often use to manage stress is to take a break from the things stressing me out and do something relaxing. For example, If I'm having trouble on a test and am feeling stressed out, I'll take a quick 5-10 minute break to go outside and take a quick walk, play with my dog or cat, etc. However, if your break is just laying in bed and going on your phone, you won't feel nearly as refreshed as you would if you went outside to get some fresh air, or just be mildly active.
