Answer:
A) Massive stars
Explanation:
The mass of the star determines how its end will be. The less massive will give rise to nebulas, in whose center a white dwarf will remain, which is a degenerate star that has exhausted all its fuel and is much smaller than its initial volume. And the most massive stars will become stars of neutrons, quarks, or, if they have enough mass, in black holes. For a star to end its days in the form of a neutron star it is necessary that it has a mass of at least 1.44 solar masses. This value is known as the "Chandrasekhar limit", and we owe it to the Indian astrophysicist Subrahmanyan Chandrasekhar, when we talk about neutron star we mean that it can lead to the formation of other objects
For a star to end its days in the form of a star of quarks or a black hole it is necessary that its mass be even greater. This value is set by the "Tolman-Oppenheimer-Volkoff limit", currently established by astrophysicists at approximately 2.17 solar masses. Everything we have seen so far about the life of the stars is very important because it can help us understand the phenomenon that causes the formation of a black hole.
Answer:
Option A. is correct
Explanation:
Latitude is the measurement of the distance from north to south and it ranges from 0° at the Equator to 90° at the poles (North or South). The imaginary lines highlighted on the map travel from north to south and are used to measure the distance from the Prime Meridian. They are lines of latitude.
Option A. is correct
Answer:
A
Explanation:
I did the assignment! :D
Answer: Yes, we can fulfill all our electricity needs through solar energy as the solar panel can absorb solar energy at night and convert them to electrical energy and discharges both on day as well as night.
A glacier that covers a wide area is called a continental glacier.
Hope this helps.
