Answer:
B. they must be intrinsically far more luminous than the brightest galaxies.
Explanation:
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.
Answer:
baking bread with yeast is chemical change
You are going 94.737 km/h or 26.316 m/s
speed = distance/time
look up a speed calculator if you have more problems like this, it’ll save you time :)
<u><em>what is frame of reference:</em>
</u><span>it is set of fixed points which are inter related on the basis of rest and motion..,, or an explanation of what an observer is doing..
</span><u><em>examples:</em>
</u><span>1 ,, if you are in motion and observing something then frame of reference is motion... and if you are at rest then frame of motion is rest...
</span><span>2 frame of reference may be place like if a passenger is sitting in a car then he is in motion with respect to the ground but he is at rest with respect to the car in which he is sitting ...
</span><span>3 also if a passenger is in car and he is tossing a coin and you are on the ground ,, then for passenger it is in vertical motion but for you it is in parabolic arc .. hence there are two different views for two persons for the same thing i.e coin... :)</span>
