Answer:
E.
Explanation:
The photovoltaic cell is an electronic device that produces electricity when exposed to light particles. It is commonly known as solar cells.
Solar cells are used to convert sunlight energy into electricity. Solar cells are those non-mechanical devices that help to change solar energy directly into electricity. This process of conversion is known as the photovoltaic effect.
Therefore, option E is correct.
<u>ANSWER:</u>
Hurricanes so frequent in areas close to the equator because "the ocean water can evaporate more quickly near equator".
<u>EXPLANATION:</u>
- Hurricanes are fast moving wind storms that use heat and most air as their fuel. The air near the 'equator' is warm and moist causing more hurricanes.
- The warm and moist air from the 'ocean surface' rises above and generates an "area of low pressure".
- This causes air from nearby areas to move to the area of low pressure. This new air becomes moist and warm. This warm air when cools forms clouds.
- This cloud systems and winds grows and spins fed by the "water evaporating" from the surface of the ocean. This in turn creates a storm called a hurricane.
Germany is well known to have big problems with the aging population, and its very low fertility rate. This contributes to a highly deformed population pyramid, where the lowest part of the pyramid is becoming thinner and thinner, while the middle section is significantly increasing, as well as the upper part of the pyramid that becomes thicker and thicker because of the long lifespan in the country.
In the next twenty years, Germany will face stagnation in the number of population, and this will be because the minorities (mainly the Muslims) will be balancing the numbers because of their very high fertility rate. In the next 50 years, with this trend, we will witness a big drop in the numbers of the ethnic Germans, and very big increase in the numbers of the minorities (mainly Muslims) which will also contribute to the country's population to start to increase again.
The only direction they can travel is north from the South Pole.
A large part of that land area is not conducive to farming or general use. The Canadian Shield covers about a third of the nation. The Arctic permafrost probably covers another third. You cannot farm in either of these areas and the cost of building roads and infrastructure in or through these areas is very high. Other areas have land that could be used for farming but the season is too short. On the lands that are arable, Canadians are reasonably densely populated.
<span>As to softened immigration process, the percentage of permanent residents (generally recent immigrants) has remained fairly steady at less than or at 1% of the population for at least 50 years. Since the birthrates for multi generational Canadians (Canadians whose grand parents or before were immigrants) is so low, Canada needs immigrants to maintain the population at a sustainable level. Yet the processes have not gotten easier. The most recent iteration of the Immigration act has extended the time required for a landed immigrant to live in Canada before being eligible for citizenship (from three years in five to four years in six).</span>
