C. The climate on Venus is a "runaway icehouse," a positive feedback that perpetually keeps the planet cold. D. The two major factors determining the Earth's temperature are the Earth-Sun distance and the concentration of oxygen in the atmosphere.

Answers

Answer:

The true statement is option D. The two major factors determining the Earth's temperature are the Earth-Sun distance and the concentration of oxygen in the atmosphere.

Explanation:

The distance between the sun and the Earth is one of the factors that determines the temperature of the planet. The energy from the sun travels to the Earth, increasing the temperature.

The other fact that has a role in the Earth's temperature is the concentration of oxygen in the atmosphere. It can increase or decrease the temperature according to the amount of this. Oxigen contributes to the greenhouse effect, which helps to keep the temperature in a range that allows life to happen.

What are the similarities and differences between the activities of early settlers and those of later settlers?

Answers

Answer:

If you are talking about settlers who went to America...

The first settlers came to escape religious persecution (the pilgrims), and eventually they also got tired of British rule so they wanted to separate from Britain. Later settlers came because they wanted to seek freedom in the new world that they didn't receive in their own old homeland.

Which of the following events was NOT a cause of the Russian Revolution?

A. poor working conditions in cities

B. Czar Alexander II's limited reforming

C. government policy known as "Russification"

D. adoption of Marxism

Answers

Answer:

B   but don't be surprised if it is D.

Explanation:

Russification was a thorn in the side of the rulers. People do not like giving up their culture. It was a cause.

The cities were poor -- especially after the disaster they suffered in WWI. The nobility was not liked. That was a cause.

Czar Alexander may have been slow to reform, but he was not the main culprit. I think this is an answer you should consider carefully. (B)

I would use the adoption of Marxism. That was not made official until After Lenin came to power. The vocabulary was often used by the leaders, but most of the peasants didn't know it's meaning.

The answer is between B and D. I would pick D, but I think you are intended to answer B.

Answers

Answer:

caliph - successor to Muhammad

Zionism  - the movement to establish a Jewish state

Aliyah -  immigrations of Jews to the holy land

diaspora - a group that is scattered outside it traditional homeland

Explanation:

After Muhammed died he was succeeded by Abu Bakr, the first of the caliphs. Because of internal conflicts, from 661 new Caliphate - Umayyad was  established, although Abbasid Caliphate made even larger impact.

Jewish diaspora was created after the exile of Jews, from their homeland, most notably during the Babylonian captivity. They were scattered across the globe, but with the rise of Zionism movement in the second half of 19th Century, idea to return Jews to their homeland started spreading. Aliyah happened once more, as in the times of Abraham and Moses.

B. are responsible for natural contaminants such as soot, dust, and organic waste. C. include global warming, which is greatly enhanced by society's production of greenhouse gases. D. began as early as 20,000 years ago as humans began to modify ecosystems.

Answers

Answer:

C. include global warming, which is greatly enhanced by society's production of greenhouse gas

Explanation:

Human activities such as burning of fossil fuel, industrial waste has lead to the emission of greenhouses such as carbondioxide, carbon monoxide, methane, chlorofloro carbon accumulation of which in the atmosphere leads to global warming as a result of the depletion of the ozone layer and the direct impact of sun on the earth.

The depleted ozone layer has lead to the constant and high temperature

that is affecting the earth.

Green plant,trees are natural users of carbondioxide but deforestation of this trees has also reduce the use of carbondioxide making it abundant in the atmosphere.

If the vertex of image Q’ is located at the coordinates (16,8) was dilated by the scale factor of 2, what was the coordinates for the pre-image Q?

Answers

Answer:

The pre-image Q is [tex]Q(x,y) =(8,4)[/tex] .

Explanation:

From Linear Algebra, we can define dilation by the following expression:

[tex]Q'(x,y) = O(x,y) + k\cdot [Q(x,y)-O(x,y)][/tex] (1)

Where:

[tex]O(x,y)[/tex] - Reference point, dimensionless.

[tex]Q(x,y)[/tex] - Original point, dimensionless.

[tex]Q'(x,y)[/tex] - Dilated point, dimensionless.

[tex]k[/tex] - Dilation factor, dimensionless.

If we know that [tex]O(x,y) = (0,0)[/tex], [tex]Q'(x,y) = (16,8)[/tex] and [tex]k = 2[/tex], then the original point is:

[tex]Q'(x,y)-O(x,y) = k\cdot [Q(x,y)-O(x,y)][/tex]

[tex]Q(x,y) = O(x,y) +\frac{1}{k}\cdot [Q'(x,y)-O(x,y)][/tex]

[tex]Q(x,y) =(0,0)+\frac{1}{2}\cdot [(16,8)-(0,0)][/tex]

[tex]Q(x,y) =(8,4)[/tex]

The pre-image Q is [tex]Q(x,y) =(8,4)[/tex] .
