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.
I don’t think so because people think Africa is poor and has little water
The North Star appeared to move higher in the sky.
Answer: Option 3
<u>Explanation:</u>
North star is a special star found in the sky which is said to be fixed in the sky and does not move from it's place and the reason for this is that this star is very near to the axis of the planet Earth and is the only star that does not change it's position in relation to the rotation of earth. So since Albany is to the north of the New York city, the star will appear to move higher towards the north in the sky.
