Answer:

The US believed that, as the world's super power, they should be in charge of overseeing the continent. The US saw little point in making claims to the frozen continent because settlement would be nearly impossible

List and describe the three levels of social class in the Neolithic Age
Ganezh [65]

Answer:

I SUGGEST READING ALL OF THIS IT IS REALLY IMPORTANT FOR THE SUBJECT

Explanation:

Domestication of animals and plants is often attributed to Neolithic revolution. Neolithic revolution is used to described change from hunting gathering economy to an economy based on farming and the Technologies that included polished stone tools pottery, and weaving. According to Scholars the Neolithic evolution is as important as industrial revolution or maybe more than that because without agriculture there would never have been an industrial revolution in first place. But using the word "revolution" misleads because industrial revolution took around hundred years where is Neolithic revolution took almost 3000 to 4000 years. Where is Industrial Revolution can be attributed with inventions such as steam engine, but on the other hand domestication of plants and animals cannot be considered as invention. Infact it was a very slow and gradual process in which humans according to their needs and requirements manipulated the traits of animals and plans for their advantage. The term Neolithic was coined by Sir John Lubbock in 1865 in his book Prehistoric Times to denote an Age in which the stone implements were more varied and skilfully made and often polished. V. Gordon Childe defined the Neolithic-Chalcolithic culture as a self-sufficient food producing economy. M.C. Burkitt further outlined some characteristic features for the Neolithic culture such as the practice of agriculture, domestication of animals in terms of economic life and grinding and polishing of stone tools, and also manufacture of pottery in terms of technology. These concepts have been modified time to time with new research and archaeological evidence found at different sites all over the world. The Neolithic or New Stone Age denotes to a stage of human culture following the Palaeolithic and Mesolithic periods and is characterized by the use of polished stone implements, development of permanent dwellings, cultural advances such as pottery making, domestication of animals and plants, the cultivation of grain and fruit trees, and weaving. The change in the economic mode and life style from hunting/gathering/foraging to primitive farming appeared so abruptly that this overall change in human life is often referred as the “Neolithic Revolution”. Slowly in course of time, the later Neolithic periods with the discovery of smelting and the creation of copper tools have been identified as Chalcolithic period and then, cultures with bronze artefacts have been given the name or coined as Bronze Age. These developed periods with invention of different metals with developed agriculture and farming activities led to the emergence of more complex societies. All of these complex societies emerged in the fertile valleys of different river located in different parts of the globe. Some of these early groups settled in the fertile valleys of the Nile, Tigris-Euphrates, Yellow, and Indus Rivers. These settlements with surplus agricultural product and trade subsequently resulted in the rise of the great civilizations in Egypt, Mesopotamia, China, and India.

5. (Sourcing) Newspapers frequently ran articles about anarchists and the threats
-BARSIC- [3]

The correct answer to this open question is the following.

Although there are no options attached we can say the following.

Newspapers frequently ran articles about anarchists and the threats posed by "radicals" in 1919 and 1920. The newspapers were interested in running these kinds of stories because these are sensationalists newspapers that love to create more drama and fear with their stories. The more drama the more people wanted to buy the newspaper to read the news. That has been one of the unofficial precepts of "Yellow Journalism," or sensationalistic news: caught people´s attention through drama.

How might this have influenced the Palmer Raids?

Heavily. That kind of news coverage generated fear in American citizens who were scared about the presence of anarchists and communists in the United States.

The main effect of the Palmer Raids was that they brought about the end of the red scare by clearing several supposed radicals. US President Woodrow Wilson ordered Attorney General Michael Palmer to execute the Palmer Raids to imprison anarchists and communists.

Consider that the capacitor is initially not charged and the voltage of the battery is 3.00 V. The switch is closed at ????????
EastWind [94]
  • Your question has some difficulties in symbols and variables to read. That's why I am re-writing (re-arranged) the Question's statement again which is:

Question:

For the R-C circuit shown in figure 1 on page 3, R= 100 ohms and C=1.00F.

A)What is the time constant of the R-C circuit?

B) consider that the capacitor is initially not charged and the voltage of the battery is 3.00 V. The switch is closed at t=0. Using the appropriate formulas, write down the voltage Vc(t) on the capacitor and the current I(t) in the circuit.  

C) consider that the capacitor is initially fully charged to 3.00 V. The switch is open at t=0. Using the appropriate formulas, write down the voltage Vc(t) on the capacitor and current I(t) in the circuit.

  • Your Question is missing the figure as well, which is attached below, please find it in the attached file.

Answer:

Part.A

100 seconds

Part.B

Vc(t)=0V

I(t)=30mA

Part.C

Vc(t)=3.0V

I(t)=0A

Explanation:

<u>Given Data:</u>

Resistance=R=100 ohms

Capacitance=C=100F

<u>Part.A: Time constant=T=?</u>

<u>Time constant:</u>

Time required to charge the capacitor upto 63.23% of the applied voltage is called a Time constant.

As we know that time constant for the RC (circuit having only resistor and capacitor) is equal to product of resistance and capacitance

T=R*C

so T=100*1

T=100seconds

<u>Part.B: Vc(t) and I(t)=? If switch is closed</u>

<u>Given Data:</u>

Voltage of the battery=Vs=3.0V

Capacitor is not charged initially and switch is closed at t=0 means that the circuit will become short (because capacitor is charging) in which current I(t) exist and voltage Vc(t) is zero.

<u>Short circuit: </u>

The circuit in which current is maximum and voltage is zero.

Thus voltage on the capacitor is Vc(t)=0V

Now we can find I(t) as follow:

Thus, Applying Kirchoff's Law (sum of all voltages is zero) on the circuit in the figure attached below, we get

V_{s}-V_{R}-V_{c}(t) =0

putting values, we get

3.0-I(t)*R-0=0

I(t)*100=3

I(t)=\frac{3}{100}

Current in the circuit is I(t)=0.03A\ OR\ 30mA

<u>Part.c: Vc(t) and I(t)=? if switch is opened</u>

If switch is opened and capacitor is fully charged then the capacitor will act as a battery and will supply will voltage as it has stored the charge. The switch is open it means the circuit is open.

So current I(t) in the circuit is zero=0A

and voltage Vc(t) exist which can be found as:

Applying Kirchoff's law, we get

V_{s} -V_{c}(t)=0 \\V_{R}\ does\ not\ exist\ because\ current\ in\ the\ circuit\ or\ through\ resistor\ is\ zero

V_{s}=V_{c}(t)

<u>thus voltage on the capacitor is </u>V_{c}(t)=3.0V

Historians often praise Thomas Jefferson for incorporating the Enlightenment into the Declaration of Independence. Which of thes
Marta_Voda [28]

Answer:

Correct answer is C) the philosophies of John Locke and Montesquieu are used

Explanation:

C is the correct because when writing his famous part about life, liberty and pursuit of happiness he used the ideas of John Locke. As he was familiar with the ideas of French Enlightenment that is why he was able to use their philosophy.

A is wrong because Declaration wasn't written in France.

B is not correct because it was written in 1776.

D is not correct because reference it self is not enough to prove this theory.
