Answer: The Earth is a closed system for matter

That is a list of all basic elemental materials on our planet. Because of gravity, matter (comprising all solids, liquids and gases) does not leave the system.

What factors contributed to the westward expansion of the u.s?
Scrat [10]
A biggie: the transcontinental railroad. Because it would economically improve wherever it was, both the North and the South competed for the railroad to be in their respective territory, evidenced by the Kansas-Nebraska Act and the Gadsen Purchase and induction of California as a free state in 1860.

In addition: people could get land cheap because it was abundant and might leave to start afresh economically.

There's other stuff I can't remember as clearly, but there's a little and I hope it helps :)

The search for black holes has so far turned up some fairly convincing stellar-sized candidates in binary star systems. What obs
ozzi

Answer:

Th similarities between the black hole and the neutron star is that they are formed from dead (dying) starts. But they come from different parent stars, if the parent star is 1.4 times the mass of the sun, a neutron star will be formed, but if the parent star is twice the mass of the sun a black hole is formed.

Explanation:

A black hole is defined as an area of space whereby the matter is so compacted that nothing can escape from it. This area is called <em>event horizon. </em>Black holes are formed when an enormous star dies in z supernova. They weigh at least twice the sun's mass, and their mass is directly proportional to their radii.

Neutron stars are created during supernova and maintained by a neutron called <em>degeneracy pressure.</em> Neutron star has a small radius, typically 30 km, with a very high density made up of compacted neutrons.

ASAP, What are some conflicts or issues surrounding immigration and multiculturalism in the U.S. and the world? Can these issues
anyanavicka [17]

Answer: A major conflict surrounding immigration/multiculturalism both in the US and in the world is the topic of refugees from the Middle East. The conflict comes from the opposing views toward these refugees: Opponents believe that these immigrants will only bring the issues of their country as well as unfair job competition, while supporters believe that their own country has an obligation to help these innocent people. While it's not possible for a complete resolution (there's no way both sides will be 100% pleased with the outcome), there are compromises that can be made (both politically and morally) in order to determine the most correct and least harmful solution for everyone involved.
