how can radioactive decay be used to date rocks?

Answers

Answer 1

Answer:

To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.

Which empire's invasion did Chandragupta Maurya help to defeat? the Turkish empire the Greek empire the Chinese empire the Egyptian empire​

Answers

Answer:

The Greek

Explanation:

He defeated Alexander

Greek empire's invasion did Chandragupta Maurya help to defeat. Thus, option B is the correct option.

Chandragupta Maurya, the founder of the Maurya Empire, played a pivotal role in repelling the Greek invasion led by Alexander the Great. As Alexander's empire extended its reach into the northwest regions of the Indian subcontinent, Chandragupta Maurya emerged as a formidable opponent.

With strategic prowess and a well-organized army, he successfully resisted Alexander's forces and managed to defeat the Greek empire's invasion. This momentous victory not only secured the independence of the Indian territories but also laid the foundation for the powerful Maurya Empire, which would subsequently flourish and become one of the largest and most significant empires in ancient history.

Thus, option B is the correct option.

Example cited in the excerpt? The Grimms found stories that express real-life situations. The Grimms embellished stories with more details in their final editions. The Grimms wanted to stick to oral reports of folk tales. The Grimms changed stories to be less dark in the final edition.

Answers

This question is incomplete. I've found the complete question online. It is the following:

Read the excerpt from "How the Grimm Brothers Saved the Fairy Tale." In contrast to the final 1857 edition, most of the tales in the first edition are shorter and sparser. They have a rawness that was later to be refined. For example, "Rapunzel” is embellished a great deal in the final edition:

First Edition

Once upon a time there lived a husband and wife who had been wishing for a child for many years, but it had all been in vain. Finally, the woman became pregnant.

Now, in the back of their house the couple had a small window that overlooked a fairy’s garden filled with all kinds of flowers and herbs. But nobody ever dared to enter it.

Seventh Edition

Once upon a time there was a husband and wife who for quite some time had been wishing in vain for a child. Finally, the dear Lord gave the wife a sign of hope that their wish would be fulfilled. Now, in the back of their house the couple had a small window that overlooked a splendid garden filled with the most beautiful flowers and herbs. The garden, however, was surrounded by a high wall, and nobody dared enter it because it belonged to a sorceress, who was very powerful and feared by all.

Which idea does the author develop with the text example cited in the excerpt?

A. The Grimms found stories that express real-life situations.

B. The Grimms embellished stories with more details in their final editions.

C. The Grimms wanted to stick to oral reports of folk tales.

D. The Grimms changed stories to be less dark in the final edition

Answer:

The idea the author develops with the text example cited in the excerpt is:

B. The Grimms embellished stories with more details in their final editions.

Explanation:

The author of the excerpt we are analyzing here states that the Grimm brothers embellished their stories as they revised them in further editions. That is what he uses the example for: to serve as evidence for that claim. The example allows readers to compared a passage of the first and the seventh editions of "Rapunzel", by the Grimms. It can be easily seen that the seventh edition version is written in a different, less raw or direct style.

Answer:

B, The Grimms embellished stories with more details in their final editions.

Adolf Hitler took office and his speeches fueled the anger of all the germans

They terrorize the most of Europe basically, trying to takeover all land of non germans.

the most notably attack was the blitzkrieg that took place on poland

Explanation:

World War I was fought between many countries, including Britain, France, and Russia on one side and Germany on the other. The war ended with an agreement known as the Treaty of Versailles. This treaty blamed Germany for the war and required that it pay the other countries for the war. This caused the Germans to resent the other countries and was one of the factors that led to World War II. Another issue leading to World War II was an economic depression that affected the German economy. Money became worthless, people lost their jobs, and citizens blamed their government. The Germans were looking for relief and change. Adolf Hitler appeared around this time and provided the type of relief that the German people were looking for. He started a fascist government and became Germany’s dictator. He also started Nazi policies, which discriminated against the Jewish populations and tried to regain German territory that was lost in World War I. These actions made other countries uneasy, and World War II started when Hitler invaded Poland in 1939.

The main reason why Abraham Lincoln helped the union win the war was because he went from limited to total warfare. Meaning he did everything in his power to help win while being practical at the same time. Thinking about what people cared about opposed to what was best. Also he valued each state and doesn't want them losing their support towards the union and by thinking politically and militarily he was able to do so in a smart way.

Answers

Explanation:

March 13th, 1840

we've begun heading west, getting all of our food and essential resources together in the wagon. its a good thing my brother is a doctor, snake bites and broken limbs have been reported from travelers before us.

our religion isn't practiced here, as Mormons we need to be in a new area in the west as others have said.

April 2nd, 1840

today was the first wound besides thrist and hunger we've encountered. my young niece fell out of the wagon on one of our stops, breaking her arm we'd assume. her father is helping her but we need to get going before it gets too hot.

April 14th, 1840

we've come across a little townie settlement, Fort Laramie. we've restocked our resources and we'll be on our way again soon. my wife is going tk have another baby soon and we don't know what we'll do if the baby is ready to come whe we are in an area we can't stop at.

may 6th, 1840

my pregnant wife and young niece have been bitten by a snake with unknown origins. we don't know how this will effect their health or the baby.

may 8th, 1840

two members of our wagon group have passed away, my wife and my young niece. my brother who is a doctor couldn't help them anymore, leaving only me, him, his wife, and my son.

June 17th, 1840

today we are planning to cross a river by cocking and boarding the wagon, but I am scared to go because we don't have a lot of food to spare, and if any is lost we'll starve.

June 18th, 1840

we lost our entire wagon in the river, and my doctor brother drowned to death. we've been walking for about an hour but since his wife is newly pregnant, its hard for her to walk.

June 23rd, 1840

after a few days of walking we've paid money to ride in a wagon with a few other people, a mother and father with a baby and a daughter.

The Oregon Trail was a roughly 2,000-mile route from Independence, Missouri, to Oregon City, Oregon, which was used by hundreds of thousands of American pioneers in the mid-1800s to emigrate west. The trail was arduous and snaked through Missouri and present-day Kansas, Nebraska, Wyoming, Idaho and finally into Oregon. Without the Oregon Trail and the passing of the Oregon Donation Land Act in 1850, which encouraged settlement in the Oregon Territory, I would have been slower to settle the American West in the 19th century.

O Ladybugs encounter a variety of dangers.

O It is challenging to capture ladybugs in gardens.

Ladybugs encounter a variety of dangers.

Explanation:

The two articles highlight the importance of ladybugs to our ecosystem and show how important and useful they are to maintain not only the ecological balance, but for agriculture as well. However, ladybugs face many dangers during their lives, not only for natural reasons, but also for the manipulation of human beings in the ecosystem.

What do the data on accidents related to teen drivers reveal

Answers

Answer and Explanation:

Teenagers should be allowed to drive from 18 years of age. This is because driving is an act of extreme responsibility, where the driver must be agile and must know how to make correct decisions in a serious and rational way. It is very difficult for young people under the age of 18 to have this degree of maturity, and it is favorable for them to avoid driving during this period. However, driving permits for 18-year-olds must have restrictions, such as having a high cognitive and psychological quality, not presenting criminal passages and strictly following traffic laws.

Hello. This question is incomplete. The full question is:

or this, Galileo was arrested and threatened with torture and death, but he refused to deny what he knew to be true. "I do not believe that the same God who has endowed us with senses, reason and intellect has intended us to forgo their use," he said.

Why does the author include this selection in the article?

Answer:

The author includes the quote to show how great thinkers like Galileo were committed and dedicated to humanism and the sciences they believed in.

Explanation:

As you may already know, many great thinkers and scientists have been persecuted and punished for their thoughts and research. Today, we know that these thinkers were correct, but at the time that they lived, people did not take well the ideas and discoveries that they obtained, causing them to suffer strong reprisals from the church and the government. The most notable example of this was the persecution suffered by Galileo, but even with so much persecution he did not give up what he knew was correct.

When the author quoted Galileo in his article, it means that he seeks to emphasize the dedication and responsibility of these authors to what they studied.
