Who are Astronomers?

An astronomer is a person also known as a scientist who studies the stars, planets, and other natural objects in space.

The twentieth century saw a revolution in astronomy. The discovery of the electron in 1897 transformed spectroscopy and introduced plasma and magnetohydrodynamic physics and astrochemistry. Einstein's E = mc2 equation solved the problem of stellar energy generation and sparked research into elemental nuclear synthesis.

One of the ways astronomers have changed the field is by collecting more light, allowing them to go deeper into space.

Therefore, Option (A) is correct.

What job given to Native Americans helped to build friendly relationships between colonists and explorers

Answers

Answer:

Chief Massasoit, a Wampanoag, and Squanto, a Patuxet Indian, helped the Pilgrims of Plymouth Bay establish their colony by teaching them skills in cultivating this land and hunting. In return for weapons and tools, these Native Americans provided the colonists with important natural resources, including food.

Explanation:

Explorers and such didnt “give” jobs to native Americans.

Native Americans had their own societies and economies way before European contact.

Europeans dealt with them as one nation deals with another: trade, negotiation, treaties, wars.

Native Americans had their own “jobs” within their “countries”.

Peaceful contact came from traders bringing more advanced European goods: cloth, steel tools, guns…and European vices (liquor) to trade for indigenously produced products: animal skins mostly.

The Cherokee, for example, began a very lucrative and lasting trade in deer skins for European markets.

Other tribes had other types of this trade.

Of course trade disputes caused friction, as did the bad effects of liquor (my speculation is that Native Americans had that peculiar intolerance for alcohol which is present in the genetics of some Oriental groups today; that may account for the seemingly more severe effect of this drug on native populations) on native societies.

Finally, colonial land pressure from an expanding population was the primary detriment to peaceful relations between natives and Europeans, exacerbated by competition between European powers who recruited natives into their wars. ( I hope this helps)

Is Canada a nation of both peacekeepers and peacemakers? If so, is peacekeeping a myth? If it is a myth, should Canadians try to live up to this myth, or should they abandon it? Explain your responses.​

Answers

Answer:

Yes, Canada is a nation of both peacekeepers and peacemakers.

No, peacekeeping is not a myth.

Explanation:

Peacekeepers country often put itself in a position as mediators between other countries that interacted with one another.  Canada has done this several times throughout history (one small example would be when Canada mediate a conflict of imports quota between United States and Mexico).

On top of that, Canada also involved in several peacemakers mission when they sent their resources to help the people who are trapped within political conflicts. (one example of this would be when Canada sent help to  Cambodia during four peace support missions from 1954 to 2000.) \

From those historical events alone, I believe Canada could be considered as a nation of both peacekeepers and peacemakers.

A president who wants to establish rules and regulations for the operation of a federal agency may do so by taking what action

Answers

Answer:

issuing an executive order.

Explanation:

A president can be defined as an individual who is duly elected by the electorates and as such is the head of the country in a democratic government. The president is empowered by the constitution to sign (veto) legislations, adjourn or convene the legislative body (Congress), grant state pardons and reprieve to citizens, command the armed forces, and welcome ambassadors representing other countries.

In the United States of America, the president has various powers granted by Acts of Congress and Article II of the U.S constitution such as Ordinance power, Appointment power, Implied power, Executive power etc.

An executive order is mainly a direct law from the president of a country and it is granted based on an executive power. By virtue of an executive power, the president is empowered to issue an executive order such as a decree, instructions, regulations and rules in order to successfully manage the affairs of the country and good governance.

Hence, a president who wants to establish rules and regulations for the operation of a federal agency may do so by issuing an executive order.

Using complete sentences, explain at least three benefits and three challenges of living in a region with monsoons. Make sure to use examples to support your answer.

Answers

Answer:

Benefits and Challenges of living in a monsoon region.

Each season comes with some benefits and also with some challenging situations. So does monsoon season. Few benefits for people residing in monsoon regions are:

1.Water is the most essential need for a living. And monsoon helps fill the rivers and lakes which people can then use it. So basically people living in monsoon prone areas will hardly have water shortage.

2. Rainy season is also very important for animals and crops.

3. Talking about the temperature, monsoon regions always have a cool and warm atmosphere which liked by all.

While enjoying the benefits of monsoon, there are some challenging factors as well-

1. The most common challenge one can face is diseases which come from rain water. All water borne diseases is dangerous to health and can be cured soon

3. Another challenging situation comes when there is flood. For example, if one wants to reach urgently somewhere, then going at destination can be difficult.

3. Lastly, if rain is beneficial for crops, then excess rain can also damage them thus a great loss in agriculture has to be faced.

Answer:

Monsoons in South and Southeast Asia often bring in too much moisture and create great floods. People living in these regions have had to learn how to adapt to these floods. One of the ways they have done this is by building structures on stilts, including homes, businesses, schools, and all other buildings in a village. This allows high flood waters to pass through the region without destroying villages. Buildings are often open-air structures; they are open rooms that can dry quickly after waters pass through. Another type of structure used to adapt to monsoons are the floating buildings in villages near the Tonle Sap Lake. The structures were built to rise and float on the water as needed. Using both of these types of structures has allowed people to conduct their daily lives with little concern over rising flood waters. People do not have to spend much time preparing for the flood waters or rebuild structures every year.

Why were upper class members of newly conquered lands given Roman citizenship?

Group of answer choices

to make them loyal to the empire

to help recruit solders into the army

to allow them to vote for the emperor

to increase the population of the empire

Answers

Answer:

to make them loyal to the empire

Explanation:

Rome had a strategy to keep the peace in the colonies and conquered lands – they would give one form of Roman citizenship to the upper-class people of the conquered land. The final goal was not to assimilate these people and turn them into Romans but to give them something to value and to make them happy.

This way, they would feel content, have basic rights, good life, and do not need rebellion. They would feel loyal to the empire and emperor because they would have a certain benefit from them.
