Alex rode her skateboard to the library. Her velocity changed from 3 m/s west
to 1 m/s west in 4 seconds. What was her acceleration?
O A. -2 m/s2 west
O B. -4m/s2 west
OC. 0.5 m/s² west
OD. -3 m/s² west

Answers

Answer 1

Answer:

a = 0.5 m/s²

Explanation:

Given that,

Initial velocity, u = -3 m/s (west)

Final velocity, v = -1 m/s (west)

Time, t = 4 s

We need to find the acceleration of Alex. Acceleration of an object is the rate of change of velocity per unit time. So,

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{\left(-1\right)-\left(-3\right)}{4}\\\\a=0.5\ m/s^2[/tex]

So, her acceleration is 0.5 m/s². Hence, the correct option is (c).

What does the Supremacy Clause do? Question 2 options: Declares the U.S. a super power Establishes state governments Makes state constitutions the highest law of the land Makes the U.S. Constitution the highest law of the land

Answers

Answer:

The Supremacy Clause:

D. Makes the U.S. Constitution the highest law of the land.

Explanation:

The Supremacy Clause is a term used to refer to the Article VI, Paragraph 2 of the U.S. Constitution. According to the Clause, the federal constitution and federal law in general are higher in a hierarchic level than the state constitutions and laws. That means no state law should conflict with the Constitution. State judges must also follow the federal Constitution, laws and treaties.

This is the text of Article VI, Paragraph 2:

This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any thing in the Constitution or Laws of any State to the Contrary notwithstanding.

Look at some of the examples of the Golden Rule that appear in religious texts. What commonalities do you see in these quotes? Why do you think so many religions contain a variation of the Golden Rule?

Answers

The correct answer to this open question is the following.

The commonalities that I see in these quotes about the golden rule is that they try to teach a very important lesson that we can say is universal: "do unto others as you would have them do unto you." It can be considered universal by the fact that it can be applied to any situation no matter your religious background or ethnicity.

I think so many religions contain a variation of the Golden Rule for the same reason. It is a universal principle of respect and reciprocity that is at the very basis of any long-lasting relationship. We could say it is common sense. The actions I do and the impact they have will be returned to me consistently as I did them.

Write a research-based argumentative essay for or against the importance of standing up to an injustice such as bullying. It has to be four paragraphs. The first paragraph, the introduction paragraph, needs the claim and the two reasons. One paragraph per reason. I'll give 60 points.

Answers

Answer:

  Bullying is unacceptable, and many movements exist trying to stop this act of violence and inequality among teenagers. I will formulate an argument towards the problem at hand. Being a student in high school, I see bullying among students of my age every day. That is why I will express my support in the fight against this phenomenon.  

 The experts define several types of crime. Those are face-to-face like direct name-calling; at a distance like spreading rumors, and cyberbullying. To me, the worst one is face-to-face even though experts name cyberbullying as the most dangerous one.”  

  School bullying is one of the basic issues in many educational institutions. Students may injure others. It happens in many regions of the world. This type of crime is never acceptable. The major effect of the school bullying is the dramatic change in victim’s personality. Bullying can make initially happy and mentally healthy people self-conscious, shy, non-confident, or insane. Some of them end up in asylums. The results of bullying are obvious: the person becomes anti-social and keeps away from trying new things. The victims avoid speaking in public or participating in team games. In some situations, a bullying victim can start to have previously absent anxious signs.”

 I insist on forcing all shareholders in the education sector to cooperate to decide on the ways of handling and preventing this problem until it gets worse. The shareholders and working personnel are responsible for bullying. They should guarantee the safety of every student. One of the solutions I recommend implementing to fight against school bullying effectively is through special education explaining why this type of activity is to be discouraged and measures to take if bullying takes place on the eyes of other students. The students should understand the problem

Bullying is unacceptable, and considerable movements exist trying to contain this act of inequality and violence among teenagers.

What is Bullying?

I will develop an argument for the issue in writing. Being a researcher in high school, I see bullying among learners of my age every daytime.

The specialists define several kinds of corruption. Those are face-to-face like straightforward defamation; at a distance like spreading rumors and cyberbullying.

To me, the most destructive one is face-to-face precise though professionals name cyberbullying as the considerable dangerous one.” School bullying is one of the elemental issues in considerable educational institutions.

Students may harm others. It transpires in considerable regions of the planet. This type of crime is never sufficient.

The major effect of school, bullying is the theatrical transformation in the target’s personality. Bullying can generate initially satisfied and mentally healthy individuals self-conscious, shy, non-confident, or insane. Some of them end up in asylums.

The sufferers sidestep talking in public or participating in group competitions. In some circumstances, a bullying victim can start to have heretofore absent anxious signs.”

Although, I insist on forcing all shareholders in the education sector to cooperate to decide on the ways of handling and preventing this issue until it gets worse. The shareholders and operating personnel are accountable for bullying.

Olympias was one of the wife of King Philip II and mother of Alexander the Great. She was mad when Cleopatra had a son because of the following reasons :-

According to the Historians Olympias was not Macedonian and hence Alexander was only half macedonian.It was the rule that the King of Macedonia should be someone of pure blood.King Philip divorced olympias accusing her to be half blood.
