Describe the difference between a typical galaxy and a quasar.

Answers

Answer: Hello, There! Your Answer is Below

Quasars can only exist while sufficient material is falling into the accretion disc. Once the material runs out the active galaxy becomes a regular galaxy. The quasars which have been observed are billions of light years away. This means that they are young galaxies as seen in the early universe

Explanation:

Quasars live only in galaxies with supermassive black holes — black holes that contain billions of times the mass of the sun quasars have luminosities thousands of times greater than a galaxy such as the Milky Way. Usually, quasars are categorized as a subclass of the more general category of AGN. The redshifts of quasars are of cosmological origin.

Equatorial diameter of earth is not identical to polar diameter which one is greater and why

Answers

Answer:

The Earth spins on its axis once in 24 hours. Anything that is being spun in a circle, like a stone tied on the end of a piece of string, experiences an apparent force trying to fling it outwards. This is called centrifugal force (or centripetal - I’m not going to get into the argument here that people often have about whether it’s a ‘real’ force or not) and it arises from the fact that a body in motion wishes to continue in a straight line - unless a force acts upon it. In the case of a stone being twirled around on the end of a buit of string, the string transmits the force of the hand that is holding the string and pulls inward on the stone, forcing it to travel in a circle around the person.

Write any 3 work that was related tk Ravana's death ? What things were done by him ?

The one who gave this answer will be a true Hindu ....​

Answers

Explanation:

Lord Rama asked his brother Lakshman to go to Ravana and learn something about the world. Lakshman obeyed his brother’s order and stood near dying Ravan’s head. But Ravan did not say anything and Lakshman returned to Rama. Rama then told Lakshman that whenever one wants to learn something from a person, you should never stand near his head, but his feet.

Lakshman again went to Ravana and this time he stood near his feet. Ravan aseeing Lakshman standing near his feet told him Three main secrets that would make anyone’s life successful.

1 - The first thing Ravan told Lakshman was that one should complete any auspicious work as soon as possible and keep delaying the inauspicious work as much possible.

He told Lakshman that he could not recognize Rama and therefore delayed arrival at the shelter. Hence this is his condition.

2 - The second thing he taught Lakshman was never to underestimate one’s enemy. He said that he did this mistake of understanding the monkeys and bears lesser or incompetent and he lost the battle against them.

He said, when he asked Lord Brahma to make him immortal, he said no one else except for monkeys and human could kill him. This is because he believed that both these living beings were not capable to kill him.

This was his mistake and he suffered life as a result.

3 - The third and final thing Ravan told Lakshman that one should not reveal one’s life secret to anyone in the world. Here also Ravan made a mistake as Vibhishan knew the secret of his death. Ravan knew this was his biggest mistake of life.
