Answer:
Rank of the stars from shortest to longest distances:
Barnard's Star (M4)
61 Cygnia A (K5)
Alpha Centauri A (G2)
Sirius (A1)
Spica (B1)
Explanation:
The habitable zone, also known as the circumstellar habitable zone, is the range of distances from a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets.
The location of a star’s habitable zone is dependent upon its luminosity, which is the amount of light emitted by an object in a unit of time, because a star’s luminosity increases with time; and also the star's mass.
The inverse square law of light brightness can be used to determine the extent of the habitable zones for different luminosity stars with the formula:
star boundary = Sun boundary × squareroot[(star luminosity)/(Sun luminosity].
Small scale manufacturing industries in cottage industries play a very important role in the economic development of India if any amount of capital is invested in small scale industries it will help in reducing unemployment in India and increasing self employment
Answer:
Decline
Explanation:
From the studies that have been done it is expected that the global birth rate will decline after 40 years. There are many reasons for this expectation, some of which are the development of the less developed countries, the people from the villages to move to the cities, more and more people to be out of the poor category, and focusing on careers as the countries develop. Some nations are still expected to have relatively high birthrates, but the majority of the countries will have significant drops in the birth rates, thus the global population will gradually start to slow down its growth, and further in the future stagnate, and probably starting to lower down gradually.
