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.

Also known as Capitalism, what economic system is based on free actions of producers and consumers?
levacccp [35]

Answer:

b. Free Enterprise

Explanation:

A "free enterprise" is dependent on the economy's <em>supply</em> and <em>demand</em>. It provides both the consumers and the producers the freedom in doing business transactions.<em> The producers are free to produce what they want while the consumers are free to buy what they want.</em> This also means that businessmen have the option to choose what business they want to open and employees have the option to choose what job they want. Such kind of economic system drives <u>competition.</u> For example, if the demand for leather shoes rises, then many of the businesses will be inclined to produce the same product.<u> This gives the consumer many options</u>. Businesses will then try to become more creative in marketing the same product at a lower cost in order to attract more consumers.
