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.

What is 4 times 27 plus 5 times 34 take away 94?
4 times 27 plus 5 times 34 take away 94 is equal to 184.
How big is Messier 83?
Messier 83, also known as the Southern Pinwheel Galaxy, is approximately 15,000 light-years in diameter. It is classified as a barred spiral galaxy and is located about 15 million light-years away in the constellation Hydrus. Its prominent spiral structure and bright star formation regions contribute to its striking appearance in the night sky.

Which depth cue accounts for why parallel lines appear to grow closer together the further away they are?
monocular constancy
How many times as bright as a light that is 90 m away from you does a light that is 10 m away from you appear?
A light that is 10 m away appears 81 times brighter because brightness decreases by the square of the distance. This is calculated using the inverse square law, which states that intensity or brightness is inversely proportional to the square of the distance from the source.
A bright star can appear dimmer than a less bright star if the bright star is?
If the bright star is located farther away from Earth than the less bright star, it will appear dimmer due to the inverse square law of light intensity. The amount of light reaching Earth decreases with distance, so a closer, less bright star can appear brighter than a further, brighter star.
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.
Why parrot fish doesn't like light?

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.
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.
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 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.
How does the relative distance of objects from the earth affect 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.
What is the relationship with brightness and distance with stars?
Other things being equal, if a star is farther away, it will look less bright. This is the same with any light - if you move farther away from the light, it looks less bright.
