Answer:
The population pyramid in Japan shows that there are more elderly than young people and that this difference will tend to be even greater in 2050. Kenya's population pyramid, on the other hand, shows that the number of young people is much greater than that of the elderly and that this difference will also be bigger in 2050.
Explanation:
The population pyramid is a type of diagram used to show the classification of cities and countries in relation to the age of their residents.
If we look at this type of diagram related to Japan, we will have an inverted pyramid, with the base being the smallest part and the top being much larger. This means that the number of young people is less than the number of elderly people in the country. This can indicate social and economic problems, which tend to increase as the young population is scarce.
Kenya, however, shows a pyramid with a base larger than the top, which indicates that the number of young people is greater than that of the elderly. This can be explained by the low life expectancy in Kenya and the problems with condom distribution. This can also create problems for Kenya.
The correct answer is B. They were able to find the orbit of a comet and predict the year of its return.
Edmond Halley was a British astronomer, geophysicist, mathematician, meteorologist, and physicist. Alexis Clairaut was a French astronomer, geophysicist, mathematician.
They were friends with Isaac Newton that before, had built a new theory of universal gravitation.
With this new theory, Newton calculated the orbit of the Great Comet of 1680. Later, Halley used Newton’s theory to calculate the orbits of several comets - even some that were in ancient records -. The thing is: Halley noticed that some comets had similar orbits, which led him to suggest that some comets may be periodic and that they may be moving along very elongated ellipses. This way he forecasted the comets return in a period of 76 years.
Since then, the comet has carried Halley’s name.
