How many times as bright as a light that is 90 m away from you does a light that is 10 m from you appear?

It is 9 times brighter, so therefor 9 squared or 9 x 9=81 times as bright.

Why shadow get smaller and bigger in a scientifically explination?
The size of a shadow has everything to do with placement of the light source, the object, and the background on which the shadow is cast. In general, if the light source is close to the object and the background is further away then the shadow is larger than the object. The opposite is true if the light source is further away. Another part of the equation has to do with angles. This is what we commonly observe happining to shadows at different times of the day; long shadows in the morning and evening and smaller shadows around the middle of the day.
Which depth cue accounts for why parallel lines appear to grow closer together the further away they are?
monocular constancy

It is 9 times brighter, so therefor 9 squared or 9 x 9=81 times as bright.
How many times brighter will a star be than an identical star that's twice as far away?
4 times as bright. This is calculated as 1/22.
A bright star can appear dimmer than a less bright star if the bright star is?
Farther away!

How can a star give off the most light and not be the brightest in the sky?
How bright a star appears depends on both its actual brightness and how far away it is. The farther away a star is, the dimmer it appears. A bright but very distant star many therefore appear dimmer than a less bright star that is closer to us.
How does the relative distance of objects from the earth affects how they appear?
Other things being equal, the farther away an object is, the dimmer (less bright) it will appear. If no light is lost (due to gas or dust in the line of sight), there is an inverse-square law - for example, an object that is 10 times closer to another one, both of which have the same real brightness, will look 100 times brighter to us.
Describe relationship between the brightness and the distance of star from earth?
Due to the inverse square law, stars that are far away from Earth are generally dimmer than stars that are close to Earth. However, there are many exceptions, since stars can also appear brighter or dimmer depending on their luminosity.
Why isn't Polaris the brightest star?
How bright a star appears depends on how bright it is and how far away it is. While, on the whole Polaris is a very bright star it is also very far away, at least 350 light years, which makes it appear dimmer. The brightest star in the night sky is Sirius, one of the closest stars to Earth at only 8.6 light years. The brightest star overall, as viewed from Earth, is the sun, which is a quarter of a million times closer to us than the next nearest star.
If stars are so far away in the night sky how come human beings can still see them?
Stars are incredibly bright objects. Many of them are in actuality as bright as if not brighter than the sun, but appear as mere points of light due to their distance.

Why are other stars not bright like the sun?
The other stars do not appear as bright as the sun because they are much farther away. Even the closest stars apart from the sun are hundreds of thousands of times farther away. In terms of actual brightness, some stars are brighter than the sun.
Why Some stars appear to shine more brightly than the others?
The stars vary in both how far away they are and in actual brightness. The closer a star is to us, the brighter it will appear. Stars also vary in actual brightness. For example, the brightest star in the night sky is Sirius. It appears bright because it is both a fairly bright star (about 25 times brighter than the sun) and is one of the closest stars to us at 8.6 light years away. The nearest star visible in the night sky, Alpha Centauri, is about half that distance but does not appear as bright because it is far less bright than Sirius in actual luminosity. Conversely, Sirius also appears brighter than Betelgeuse which is actually much brighter than Sirius but also much farther away.
