After it experiences a "helium flash" a star like the Sun will have a brief period of stability, fusing helium into carbon (and sometimes oxygen). During this brief stable stage, the star:_________a. Increases tremendously in luminosity.b. Gets to be even larger in diameter than it was as a red giant.c. Returns to the position on the H-R diagram that the star had in its main-sequence stage.d. Is able to fuse many of the heaviest elements (such as iron and gold) in its superhot core.e. None of the answers provided is the correct answer

Answers

Answer 1

Answer:

a. Increases tremendously in luminosity

Explanation:

The helium flash is a thermal nuclear fusion with large quantities of helium gas into carbon. During the red giant phase, the sun is predicted to have a flash 1.2 billion after it leaves the main sequence and this helium fusion cannot be produced by the low mass stars. The sun in this stage will burn out or run out of its fuel and eventually will lead to gravitational collapse.  The star being to shrink in size and core starts to collapse.

Hey there! I'm happy to help!

The Earth rotates counter-clockwise. If you are looking at North and South America, the earth is turning to the right. This means that which ever one is farthest to the right (the East) will have the Sun shine on them first.

As you can see, South America is more to the right, so this means that the Sun will shine light on them first.

I don't know what your text book says, but computers and cell phones are absolutely polluting.  All the emissions from the manufacturing process get released into the atmosphere, and they run on electricity which is being produced at sometype of power plant (probably coal).

Since we don't know the "now" of the text book, but we do know 2020, we know that there was a sharp increase in 2018 that started to level off in 2020 from e-waste.  It's estimated there are 3 electronic devices for every 1 person in the world.

If you were drifting off the coast of South America in the Atlantic Ocean, on which coast would you eventually wash up

Answers

On the coast of southwest Africa.

Explanation:

The Atlantic Ocen is the Ocen that divides the continent of Africa, and the continent of Europe form the continent of America (South, Central, and North America). If we drift off from the coast of South America, the continent that is parallel to this one in Africa, and if we look in a map, we can see that is in the southwest coast because the southeast coast of Africa has the Indian Ocean that is between Africa and Oceania.

If we look at the shape of Africa and South America, we can see that they fit one in another. The reason for this is that in the Old World, these continents were together, but then they started to drift apart, and the Atlantic Ocean came between these two continents.

What information is needed to investigate and describe a region by its geographic characteristics?

Answers

Answer:

The geographic characteristics of a region include aspects of both its physical geography and human geography.

For physcial geography, information on the regions orography (relief), climatology, and hidrology is needed. From these information, an accurate description of the physical land can be made, taking account atmospheric, land, and water factors.

For human geography, an important information is the demography of the place: how many people live there, what percentage of them are men and women, what is the age distribution and the ethnic profile, etc.

Another important information is to find the population pattern of the area: is it more urban or rural, are there many villages or only a few, are the municipalities connected, etc.

The principal way commercial banks earn money in a fractional-reserve system, is by obtaining money from the public, and loaning out a fraction of that money at a higher interest rate.

A commerical bank may pay for a deposit an interest rate of, for example, 2 o 3%, but when this commercial bank loans out part of that deposit, it may charge 5, 6, 7% or even more.

This is why commercial banks tend to be very profitable businesses most of the time.
