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

ervations could you make to distinguish whether the unseen object in one of these systems is a black hole or a neutron star?

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.

What is the farthest distance a human has ever been from earth?
Stolb23 [73]
In distance, it's something like maybe 245,000 miles ... corresponding to the
several Apollo missions during which a Command and Service module entered
lunar orbit and swung around the back side of the moon with astronauts aboard.

The farthest from Earth that a human has ever gone <em>and walked on solid ground</em>
is roughly 238,000 miles, corresponding to the six Apollo missions that landed
six pairs of astronauts on the near side of the surface of the moon, between 1969
and 1972 .

The three ways in which materials respond to forces:

1.Tension,

2.Compression,

3.Bending.

Explanation:

Tension- The force that is exerted when physical objects come in contact with each other.

Compression- Compression is the application of balanced inward ("pushing") forces to different points on a material or structure.

Bending- A bending force is a force that is applied to a length of material.

What kind of rock property is displayed by this symbol on a geologic map?
Tpy6a [65]

Answer:

Geologic maps represent the distribution of different types of rock and surficial deposits, as well as locations of geologic structures such as faults and folds. To read a geologic map is to understand not only where materials and structures are located, but also how and when these features formed.
