What colonial influences are evident in the languages in east africa
Jobisdone [24]

Answer:  

The Portuguese, French, British and Dutch

Explanation:

While it was the Portuguese who pioneered the earliest ventures of Europeans into Africa, they were soon followed by others. Most of the European outposts along the coast changed hands from time to time as the relative power and influence of different players waxed and waned.  The French, British, and Dutch were all major players, and much of the most lucrative trade was based on the trans-Atlantic slave trade.  European ships established a ‘triangular’ trading route, bringing goods for trade from Europe to the West coast of Africa, then taking slaves across to the New World, and returning to Europe with agricultural commodities from there.

Where is the "ozone layer" located? How and why is stratospheric ozone beneficial for people, whereas tropospheric ozone is harm
Nadusha1986 [10]

Answer:

The ozone layer is usually referred to as a blanket that protects the earth from the harmful incoming solar radiation. It is located in the Stratosphere layer but also there is another ozone layer in the troposphere, commonly known as the troposphere ozone.

The stratospheric ozone is considered to be good ozone because it is located at a high altitude and it directly acts as a shield protecting the earth from the solar radiation, which can cause various types of skin diseases and also can increase the surface temperature of the earth.

On the other hand, the troposphere ozone is considered to be bad as it is located near to the ground surface and is mainly comprised of the greenhouse gases, that are harmful to the atmosphere and also increases the surface temperature of the earth.

CFC is one of the greenhouse gases that are harmful to the atmosphere because CFC molecules are continuously hit by the solar radiations that breaks the bond between the carbon and chlorine, resulting in the production of a single Chlorine atom, which eventually breaks down down the ozone layer by reacting with it. This is how the CFCs depletes the stratospheric ozone.

The depletion of the ozone layer leads to the global climatic changing, affecting all the biotic and abiotic components of the earth. This is a long term effect. This global warming is a threat to destroy the earth, so preventive measures must be taken in order to reduce the causes and use of those substances that can lead to catastrophic changes.

Which actions were results of the United Nations’ plan to partition Palestine between the Arabs and the Jews? Select three optio
yKpoI14uk [10]

The actions which were results of the United Nations’ plan to partition Palestine between the Arabs and the Jews are as follows:

A. the disapproval of many Arab nations

B. the end of British control in the region

C.the formation of the Jewish state of Israel

<u>Explanation:</u>

  • The British government was established by the League of Nations under the Palestinian Mandate in 1923 as part of the post-World War I fragmenting of the Ottoman Empire.
  • This reaffirmed the British adherence to the Balfour Declaration in 1917 to create a "National Home" for the Jewish population in Palestine, with the sovereign right to enforce it.
  • Many proposals have sparked violent demonstrations in the Arab states, calling for a jihad and the extermination of all European Jews in Palestine.
  • Finally, the UN General Assembly implemented the proposal as "Resolution 181 (II)" on 29 November 1947.

Find the length of the missing side the triangle is not drawn to scale 17 and 15
Tatiana [17]
Okay, so you take the length of your hypotenuse (17) and plug it into the pythagorean theorem as C. And then plug the given side (15) into A or B (doesn't matter which). So: <span><span>a2</span>+<span>152</span>=<span>172</span></span> <span><span>a2</span>+225=289</span> Now isolate a^2 by subtracting 225 from both sides of the equation. <span><span>a2</span>=64</span><span> Find the square root of both sides to find the missing value. a = 8</span>
