∙ 9y agoIt is 9 times brighter, so therefor 9 squared or 9 x 9=81 times as bright.

4 times 27 plus 5 times 34 take away 94 is equal to 184.
14 times
80
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.

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.
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.
4 times as bright. This is calculated as 1/22.

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.
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.
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.
The brightness of a star decreases as the distance from Earth increases. This is due to the inverse square law principle, where the light energy spreads out over a larger area as distance increases, resulting in a dimmer appearance. Therefore, stars appear brighter when they are closer to Earth and dimmer when they are farther away.
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.

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.
Stars appear to shine more brightly than others due to differences in their size, temperature, and distance from Earth. Larger, hotter stars emit more energy and appear brighter. Stars that are closer to Earth also appear brighter, as they are more luminous when viewed from a shorter distance.
