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).

US president Donald Trump made a successful assassination of Iranian General Qassem Suleimani. As a result, citizens feared that War is a great possibility because of what happened. Investments and businesses pulled out of US and Iran due to stockmarkets downfall. Why do u think this happened? EXPLAIN.

Answers

Answer:

Financial markets tend to respond by virtue of macroeconomic and political events that occur on a day-to-day basis in the nations with the largest presence in the world economy. Thus, events such as presidential changes, political scandals or bilateral conflicts have a wide interference in the development of financial investments.

Therefore, the fact that a bilateral conflict between the USA and Iran begins, implies that the investments and businesses that are developing in these countries may have a negative development. For this reason, financial investors, after the death of Qassem Suleimani, decided to exit their investments in these countries in order to avoid eventual economic losses.

Explanation:

Our constitution does not copy the laws of neighbouring states; we are rather a pattern to others than imitators ourselves. Its administration favours the many instead of the few; this is why it is called a democracy. If we look to the laws, they afford equal justice to all in their private differences; if no social standing, advancement in public life falls to reputation for capacity, class considerations not being allowed to interfere with merit; nor again does poverty bar the way, if a man is able to serve the state, he is not hindered by the obscurity of his condition. The freedom which we enjoy in our government extends also to our ordinary life. There, far from exercising a jealous surveillance over each other, we do not feel called upon to be angry with our neighbour for doing what he likes, or even to indulge in those injurious looks which cannot fail to be offensive, although they inflict no positive penalty. But all this ease in our private relations does not make us lawless as citizens.

Miranda sat in the high school computer lab typing like mad. It was 8:30 a.m., and her 1,000-word report on The Catcher in the Rye was due at 9:00. For the past hour, she had been flipping through the ratty pages of the old paperback trying to discern the major plot points and then typing out a few sentences that she hoped were logical. The only reason she was able to get into the lab that early was because she was one of Mrs. Brodys assistants, but a couple of hours in the lab didnt make up for weeks of zoning out in English class.Miranda could kick herself, but she was too busy skimming through her notes and attempting to remember somethinganything!that Mr. Giuffreda had talked about. Mr. Giuffreda was a tough grader, and Miranda did not work well under pressurenot a great combination. On top of all that, Miranda could hear her mothers voice in her head: One more bad grade in English, young lady, and no more soccer team. Miranda failed to see the relationship between soccer and book reports, but she also knew her mother wasnt kidding. When she had slacked off in geometry last semester, her mother had taken away her cell phone for a month. Another time, when Miranda had missed her curfewagain and againshe had gotten grounded for two weeks.Still typing, Miranda thought about Mr. Giuffreda. He expected nothing but the bestand then some. He never gave extensions unless someone had a family emergency, and he had a terrible habit of brushing off even the most creative excuses. Anyway, Miranda didnt need an extra day or two. She needed time to read the entire novel again. Miranda ran a word count361. She checked her watch8:45. She flipped to the end of the book trying desperately to remember the ending, but nothing was coming to her. Why hadnt she paid attention?At 8:55, she had a whopping, miraculous 402 words. The homeroom bell had rung five minutes ago, and students were filing into the lab for first period. Mirandas fingers were still flying, but by 8:59, Mrs. Brody asked Miranda to leave so she could start class on time. Miranda saved her work on her USB drive, collected her pages from the printer, and slung her knapsack over her shoulder. Then she trudged down the hall to Mr. Giuffredas class as slowly as possible, even though she knew she would be late and would probably get detention.

Would you be able to see through walls or use your eyes to zoom in on tiny, miniscule objects? Computer chips may not give you supersight, but they may help some blind people finally see.2Replacing body parts with mechanical devices is called bionics. Scientists have been developing bionic body parts for a long time, but in the last 20 years, they have started using computer chips to make bionic devices better and more effective.3To place a computer chip in an eye, a doctor makes a tiny pocket in the retina, the back of the eye. The retina is like a movie screen, and the lens at the front of your eye focuses light onto it. The computer chip, about the size of a pinhead and thinner than a human hair, is placed inside the tiny pocket. The chip senses light and helps a person see.4Six people were in the first group to allow doctors to put chips in their eyes. The patients say the computer chips have helped them see better. Before the operation, one patient could only see objects that were a few feet away. After the operation was completed, he said he could see a flock of geese flying through the sky. Another patient who saw only darkness before the operation can now see light and shadows. "Someone came along and developed this little thing to put in your eye, and suddenly I can see more light," he said, celebrating his improved sight. "None of us had expectations that we'd be able to see someone's face or read a book. Eventually, it'll work."Which detail from the passage describes how the computer chip is placed in the eye?AThe lens in the eye focuses light onto the computer chip.BA tiny pocket is made in the retina for the computer chip.CThe computer chip is placed next to the eye because it is too big to actually fit inside.DThe patient has to remain awake because the eyes must be open during surgery.Read the passage.Which detail from the passage describes how the computer chip is placed in the eye?AThe lens in the eye focuses light onto the computer chip.BA tiny pocket is made in the retina for the computer chip.CThe computer chip is placed next to the eye because it is too big to actually fit inside.DThe patient has to remain awake because the eyes must be open during surgery.
