A. 20 years
B. 40 years
C. 60 years
D. 80 years
E. 100 years

Answers

Answer 1
the answer is a. 20 years
Answer 2

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.

Why do Earth, Mars, and Venus lack any hydrogen and helium in their atmospheres?
Their gravitational pull is too strong.
They spin too quickly on their axes.
Their masses are too large.
Their gravitational pull is too weak.

Answers

Answer:

Their gravitational pull is too weak.

Explanation:

Earth, Mars and Venus are terrestrial planets that used to have hydrogen and helium in their atmospheres. However, these light elements were lost over time as they evaporated. This is primarily due to the planets' having weak gravitational pull when compared to the other bigger planets like Jupiter, Saturn and Uranus and the planets' warmer temperature that results to having a thin atmosphere.

On the other hand, the bigger planets have large masses and are cold enough to prevent both hydrogen and helium molecules from escaping the atmosphere.

Answer:

Their gravitational pull is too weak.  Correct!

Explanation:

The terrestrial planets all have low mass, so the gravity they produce is much weaker than the sun or the Jovian planets. The gravity exerted by these planets is too weak to hold hydrogen or helium in the atmosphere.

Both P waves and S waves travel outward in every direction from the site where the earthquake occurred. If Earth’s interior were entirely solid and uniform, how would an observer experience an earthquake that took place on the other side of Earth? Use the terms “P wave” and “S wave” in your answer.

Answers

Explanation:

Both P and S-waves travels as body waves within the earth.

They are seismic waves. P-waves are longitudinal waves and as such can travel through any material medium. S-waves are transverse waves can only travel through solids.

If the earth is uniformly solid, at the seismograph station, both waves would be picked. Based on travel time, p-waves will reach the station first before s-waves.

What is the term for an independent

Answers

Answer:

An independent state consisting of a city and its surrounding territory is called a city-state.

Explanation:

There are multiple types of independent states, and there are mutliple criteriums on which the definitions are made. A big portion of the smallest states, which are also very interesting, tend to fall into the category of city-states. This type of state is basically when one major city and its close surrounding territory make up the whole state.

Such states are nothing new, as they have existed since the development of the first civilization in Mesopotamia, through antiquity with the Greek and Phoenician city-states being an example, the Italian city-states during the Middle Ages, etc. Nowadays, there are still states of this type, and good examples are Monaco, Andora, Vatikan, and San Marino.

Which of the following was not an important challenge facing Latin America immediately after independence?
A conflicts over conservative and liberal political ideologies
В. the flight of wealthy Spaniards back to Europe
C. the immediate and continued invasion by Spanish forces
D. weakened economies due to the destruction of farms and mines

Answers

Answer:

The immediate and continued invasion by Spanish forces was not a challenge for the Latin American countries after they gained independence.

Explanation:

When the Latin American countries entered into revolutions for independence they were fighting against the Spanish. One by one, all countries, with joined forces, managed to defeat the Spanish and kick them out of Latin America. The Spanish never returned even though they wanted, but they simply didn't have the economic power and military power to go to conquest again.

Once the Spanish were kicked out, the Latin American countries had their faith in their own hands, though some countries tried to interfere with it and managed to a certain degree in some of them. The Spanish were never a problem, but internal conflicts for power between different political fractions, economies in dire situations, as well as a lot of wealth being taken out by the rich Spanish that abandoned them resulted in a long and painful process to stability and creation of good conditions.

how did the nacrimea case study prove that we are naturally ethnocentric

Answers

Answer:

Horace Miner's somewhat satirical piece “Body Ritual Among the Nacirema” is an entertaining social commentary about ethnocentrism. By evoking this mode of thinking, Miner attempts to make us unwittingly use our cultural prejudices against our own societal mores.

In that it is presumed that what one nation does, or that nation's perspective on and response to crime, is universally shared, or at the very least, that it would be appropriate for everyone else.

What do you mean by the Ethnocentric?

An essential idea in the study of intergroup relations is ethnocentrism. In the context of today, it refers to the attitude that one's culture is superior to others and the employment of a lens formed from one's own culture to evaluate the contributions of another culture, frequently in derogatory terms.

The fundamental impact of ethnocentrism is the possibility for intergroup animosity and cultural disputes to develop as a result of divergent perspectives, a lack of empathy, and poor communication.

It is thought that ethnocentrism is a learnt behavior ingrained into a person's or a group's various views and values.

Therefore, in that it is presumed that what one nation does, or that nation's perspective on and response to crime, is universally shared, or at the very least, that it would be appropriate for everyone else.
