A star that looks bright in the night time sky might really be a very dim star that happens to be nearby; conversely, a faint star might really be a very luminous star that is extremely far away. Astronomers need to know the true brightness of stars; the true brightness tells us how much power is emitted from the surface in the form of starlight, and it can be calculated once the distance to the star is known. What process causes stars to emit light energy?

Compere push and pull factors that drive migration, and give two examples of each.​

Answers

Answer:

Pull factors are the ones that attract migrants (as a strong economy), while push factors are the ones that drive migrants away (like war).

Explanation:

There are numerous different factors that make people migrate from one place to another, but all of them can be put into two broad groups, pull and push factors. The pull factors are factors that attract people to migrate in as these are the factors that offer a better life. The push factors, on the other side, are the factors that make people move away as these are the factors that make life harder.

An example of a pull factor is a strong economy. A strong economy means that the society is well developed and that job opportunities will be abundant, thus there is a chance of improving the economic status and having a better life. An example of a push factor is war. A situation where there is a war means that people feel unsafe and that they may end up losing their lives, or someone from their family and circle of friends. In order to avoid such a scenario, people move away, primarily looking for countries that offer safety.

9. During the last two weeks of its cycle, the Moon is
a. crescent
b. gibbous
c. waxing
d. waning

Answers

Answer:

A gibbous moon

Have a wonderful day!

Answer:

Waning

Explanation:

The moon cycle has several phases. The moon starts off as a new moon, then waxes (or grows) into a waxing crescent moon, then it gets to its first quarter (halfway to full moon). After that it grows to its waxing gibbous stage which is more than half way illuminated. After reaching the full moon stage (fully illuminated), the moon starts to wane. The full moon becomes a waning gibbous, then reaches its third quarter stage (halfway from full moon to new moon). After waning for some more time, the moon reaches its waning crescent stage and it is almost a new moon. Upon becoming a new moon, the cycle starts again.

This whole cycle takes about 29.5 days. The full moon happens at about the halfway point (roughly 14-15 days into the cycle). This means that the moon grows for about two weeks and wanes for about 2 weeks as well. Hence, the correct answer is D. Waning (since it spends the last two weeks of the cycle waning or shrinking).

The rapid population growth is attributed to migration from other regions in the country, with migrants seeking business and employment opportunities. The population of Mumbai has more than doubled since 1991, when the census showed that there were 9.9 million people living in the area.

The population growth in Mumbai is due to two main factors: - rates of natural increase - national and international migration (mostly rural to urban) From 2001 to 2011 population in Mumbai increased by 3.4million, approximately a 50/50 split migration v's natural increase.

In many parts of the world, there is a rock layer rich in the metal iridium. Iridium is very rare on Earth, but it is relatively common in meteorites and other debris that comes from outer space. All occurrences of this iridium layer are from the same geologic epoch, at the very end of the Cretaceous. Most of the fossils in rock layers below the iridium layer, including dinosaur fossils, do not appear in layers above the iridium layer.

Based on this evidence from the rock and fossil record,
A.
meteoroids and other space debris did not impact the Earth at the end of the Cretaceous.
B.
an asteroid impact likely caused a mass extinction at the end of the Cretaceous.
