Which circuit has brighter bulb side by side?
Bulbs in a parallel circuit draw the same amount of current, so each will display the same brightness. Bulbs in a series circuit share the current so all bulbs will appear dimmer.
Do two circles with the same area have the same circumference?
YES!!! THey would be congruent circles; tjhat is appear to be the same size.
What is an angle that measures 360?
One rotation exactly. It may appear to be the same as zero degrees but sometimes the difference does matter.
What do you do when a guy says he loves you but cheats on you?
Then he either he doesnt actually love you or he likes 2 girls @ the same time. If he cheated on you, dont stay with him!! He doesnt deserve you, and you dont deserve for him to treat you like that.
What is the term for two figures that have the same shape and size?
Geometric shapes that are identical in size and shape are congruent.
Are the star in big dipper in the same brightness?
No. The stars are not only not the same brightness, they are not the same distance from us - they just "appear" to be as part of the optical illusion of earthbound astronomy. They are all of varying brightness, though fairly close in brightness overall.
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
Is it true that two stars that have the same brightness are the same distance from earth?
Not necessarily. Two stars can have the same brightness but be at different distances from Earth. The distance of a star affects how bright it appears to us, so a closer dim star may appear as bright as a farther bright star.
Why do some stars appear bigger and brighter than others?
A stars brightness depends on two factors; its distance from us and its actual brightness (absolute magnitude). The actual brightness of a star depends on various factors, such as its mass, its temperature and its age.Consider two stars of the same actual brightness (absolute magnitude) - if one of them is much closer, then is will be brighter than the further one. It will appear brighter, even though it would be the same side by side - it can be said to be apparently brighter (higher apparent magnitude) due to its distance.A:They appear bigger and brighter because they really are bigger and brighter, but even if they are not bigger and brighter it could be because they are closer.

What compares the brightness of stars as if they were the same distance from earth?

If two stars have the same absolute magnitude but one of the stars is farther from earth than the other one which star would appear brighter in the night sky?
If two stars have the same absolute magnitude, the one that is closer to Earth will appear brighter in the night sky. This is because brightness as perceived from Earth depends on both the intrinsic luminosity of the star (absolute magnitude) and its distance from us. The farther star, despite having the same intrinsic brightness, will have a dimmer apparent magnitude due to the greater distance light must travel to reach us.
What is similarities between apparent brightness and absolute brightness?
Both relate to brightness; both are measured in the same units; both are used for astronomical objects such as stars or galaxies.
If two stars have the same apparent magnitude are they the same distance from Earth?
No. Brighter distant stars can have the same apparent magnitude as fainter stars that are closer.(Absolute magnitude does not refer to actual brightness, but rather to what the brightness of a star would likely be at an arbitrary distance of 10 parsecs, rather than its actual distance.)
How does the distance and size of a star impact its brightness?
If two stars have the same size and brightness, but one is further away, it will appear dimmer. The brightness of a star is inversely proportionate to the square of its distance. In other words, a star ten light years away will be four times dimmer than one just as bright (absolute magnitude) that is only five light years away. Larger stars also tend to be brighter, though most of the really big stars are red giants.
What is the relationship between star brightness star temperature?
The Hertzsprung-Russell diagram shows absolute magnitute or brightness against it's colour (which is an indication of temperature) . This shows the main sequence, which describes the typical life of a star.
What makes some stars appear brighter than others the temperature or the size?
It is a mixture of both. A hotter star will generally appear brighter than a cooler star of the same size. Similarly, a large star will appear brighter than a small one of the same temperature. The brightest stars are generally red supergiants, which are comparatively cool stars, but are so large that their size more than makes up for it. A star's apparent brightness from any given vantage point also depends on its distance. The closer a star is to you, the brighter it will appear.
