Explain the concept of social Darwinism. How did this idea encourage European settlers to treat native Africans differently?
Please hurry
Answer:
Social Darwinism is the notion of survival of the fittest applied to social situations. It’s the idea that the strong will lead and the weaker will follow. Europeans applied this thinking to the African continent, which they viewed as less socially evolved than Europe. With this motivation, Europeans divided and conquered the African continent.
Explanation:
responses may vary right on edge
Social Darwinism gives the concept of the strong will lead and the weak will follow. Europeans applied this to Africans because they thought Africa is weaker than them and for this reason, they divided and conquered Africa.
What is Social Darwinism?Social Darwinism refers to various theories and societal practices that purport to apply biological concepts of natural selection and survival of the fittest to sociology, economics and politics, and which were largely defined by scholars in Western Europe and North America in the 1870s.
Social Darwinism holds that the strong see their wealth and power increase while the weak see their wealth and power decrease. Social Darwinist definitions of the strong and the weak vary, and also differ on the precise mechanisms that reward strength and punish weakness. Many such views stress competition between individuals in laissez-faire capitalism.
While others emphasize the struggle between national or racial groups, support eugenics etc.

Explanation:
A sample of the lava flow within the outcrop has 707 Uranium-235 atoms, and 293 Lead-207 atoms. How old is the lava flow?
Answer:
The lava flow is approximately 351.925 million years.
Explanation:
We find that atoms of Uranium-235 decays and turns into Lead-207 and that half-life of the former one is [tex]703.8\times 10^{6}[/tex] years. The initial amount of Uranium-235 is the sum of current atoms of Uranium-235 and Lead-207. The decay of isotopes is modelled by the following ordinary differential equation:
[tex]\frac{dn}{dt} = -\frac{n}{\tau}[/tex] (Eq. 1)
Where:
[tex]\frac{dn}{dt}[/tex] - Rate of change of the amount of Uranium-235 atoms, measured in atoms per year.
[tex]n[/tex] - Current amount of Uranium-235 atoms, measured in atoms.
[tex]\tau[/tex] - Time constant, measured in years.
The solution of this differential equation is described below:
[tex]n = n_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (Eq. 2)
Where:
[tex]n_{o}[/tex] - Initial amount of Uranium-235 atoms, measured in atoms.
[tex]t[/tex] - Time, measured in years.
In addition, we can calculate the time constant in terms of the half-life:
[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (Eq. 3)
If we know that [tex]n_{o} = 1000\,atoms[/tex], [tex]n = 707\,atoms[/tex] and [tex]t_{1/2} = 703.8\times 10^{6}\,yr[/tex], then the age of the lava flow is:
From (Eq. 2):
[tex]t = -\tau \cdot \ln \frac{n}{n_{o}}[/tex]
By (Eq. 3);
[tex]\tau = \frac{703.8\times 10^{6}\,yr}{\ln 2}[/tex]
[tex]\tau \approx 1.015\times 10^{9}\,yr[/tex]
[tex]t = -(1.015\times 10^{9})\cdot \ln \frac{707\,atoms}{1000\,atoms}[/tex]
[tex]t \approx 351.925\times 10^{6}\,yr[/tex]
The lava flow is approximately 351.925 million years.

The Persian Empire was brought to an end by _____. Cyrus the Great Meroë Alexander the Great Ezana
Answer:
Alexander the Great brought the Persian Empire to an end.
Explanation:
The Persian Empire was the most powerful empire and the largest empire for a very long time. It had territory stretching from northwestern South Asia to Asia Minor, and from Central Asia to the Indian Ocean. The empire functioned very well despite having a lot of different ethnic, cultural, and religious groups, it was an empire for example.
This all came to an end with the rise of the Macedonian Kingdom that turned into a Macedonian Empire. With Phillip II of Macedon laying good foundations for Alexander by reforming the army, including the Paeonian cavalry, and neutralizing the Greeks, Alexander with his military knowledge and courage set his sights to the east. Despite being heavily outnumbered and all the odds being against him, Alexander and his Macedonian phalanx supported by the Paeonian cavalry went up against the massive Persian army which was also supported by Greek soldiers.
It took several battles, in which bit by bit Alexander was gaining ground, and in the final one at Gaugamela which was the biggest one of all he made the decisive win. This ended the Persian Empire for the time being, while made the Macedonian Empire the largest in the world.

I think the most important reason for the decline of use of coal in the UK was the This is because
Answer:
The most important reason for the decline in the use of coal in the UK was pollution.
Explanation:
The UK was the first country in the world to industrialize. Its industry was based on the power produced by coal. Coal is a fossil fuel and it is highly efficient when it comes to the production of energy, and with the UK having an abundance of this resource it seemed that it is a perfect match.
The coal indeed helped the industry in the UK to skyrocket, but as time was passing it was also bringing in more and more problems. The major problem was the heavy pollution, which in turn resulted in other problems. The pollution contributed to low visibility, hard breathing, significant worsening of the health of the people, acid rains that were destroying the vegetation and caused heavy erosion. Seeing the consequences, the country moved in another direction and gradually abandoned the coal and replaced it with oil, hydropower, nuclear power, and in more recent times with renewable energy sources.

In Africa what do most people do to provide for themselves and their families
If the actual humidity at a place is 112 grams per cubic metre & relative humidity is 85%. And if the air temperature is increasing, predict the weather & justify your answer.
Answer:
The saturation vapor pressure of the air parcel will increase with the increasing temperature. The amount of pressure that each air bubble will exert will increase if the temperature is increased. This would in turn make the vapor molecules saturate just above the water molecules.
This eventually results in precipitation. At high temperature, vapor molecules take less time to saturate over the water as compared to saturation at freezing temperatures which means that rainfall is more when temperature causes saturation vapor pressure to increase.

What is the Judaism distribution?
Answer:
Judaism is mostly found in the USA and Israel, and in a smaller scale in some of the European and South American countries, though there are in other countries around the world.
Explanation:
Judaism is one of the oldest religions in the world that has managed to survive in modern times. It is the first of the Abrahamic religions and it has been the basis for the formation of Christianity and Islam later in history. The followers of this religion have been the subject of persecution and genocide multiple times throughout history, which has led to stagnation of the number of followers or drop of it.
Nowadays, the USA has the biggest number of Jews, around 12 million, while Israel, the only Jewish dominated country, has around 6.5 million Jews. Only three other countries have over half a million Jews and those are France, Canada, and Russia. Other countries where there are Jewish communities that number more than 100,000 people are the West Bank, UK, Argentina, Germany, Ukraine, Brazil, Australia, and Hungary.

Using the rule of 70 for doubling time, in how many. years will the population of mali double if its present rate of natural increase is 3.6, assuming all other indicators stay. constant
A. 20 years
B. 40 years
C. 60 years
D. 80 years
E. 100 years
The time it will take for the population of mali to double is 20 years. Which is the correct answer would be an option (A).
What is the rule of 70 for doubling time?The rule of 70 for doubling time is defined as the time it will take for your investment to double and is calculated by dividing your growth rate by 70.
For example, if your mutual fund has a four percent growth rate, divide 70 by three. Thus, the doubling time is 17.5years because 70 divided by three is 17.5.
We have to determine using the rule of 70 for doubling time, in how many. years will the population of mali double if its present rate of natural increase is 3.6.
We have been given that the present rate of natural increase is 3.6.
According to the rule of 70 for doubling time,
70 divided by the growth rate of 3.6
⇒ 70/3.6
⇒ 19.44 ≈ 20
Therefore, the time it will take for the population of mali to double is 20 years.
