Sample Response: How can magnetic and electric fields be demonstrated?
Quasar is famous for being an intergalactic object which is billions of years away from the earth yet can still be seen, unlike the other star body, unlike giant galaxies.
Hence, the fact that quasars can be detected from distances where even the biggest and most luminous galaxies cannot be seen means that "they must be intrinsically far more luminous than the brightest galaxies."
This condition, including other related evidence gotten in recent years concerning our galaxy, has shown that quasars are probably the central nuclei of very distant, very active galaxies.
The surprising thing was that quasars and active galaxies have a lot of mass in the center of the very small volume of the space.
Therefore, the surprising thing about quasars was that due to this mass and energy they are 100 times more luminous than Milky Way which means they have high recession velocity and a very large amount of red-shifting.

Answer:
Explanation:
The formula for force is:
If we rearrange the formula to solve for a (acceleration), the formula becomes
The force is 68 Newtons. Let's convert the units to make the problem easier later on. 1 N is equal to 1 kg*m/s², so the force of 68 N is equal to 68 kg*m/s².
The mass is 2 kilograms.
Substitute the values into the formula.
Divide. Note that the kilograms will cancel each other out (hence why we changed the units).
The acceleration is<u> </u><u>34 meters per second squared.</u>
2NO2 means that there is 2 oxygen atoms and one nitrogen with two sets of that. So its the third one
