If two stars have the same absolute magnitude but one of the stars is farther from earth then the other one which star would appear brighter in the night sky?
The star that is closer to Earth will appear brighter in the night sky. Although both stars have the same absolute magnitude, the apparent brightness of a star decreases with distance. Therefore, the closer star will have a higher apparent magnitude, making it look brighter to observers on 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.
How does the light from flashlight that is shone from two differences model the apparent magnitude of two starts with the same absolute magnitude?
The light from a flashlight can be used to model the apparent magnitude of two stars with the same absolute magnitude by demonstrating how distance affects brightness. Just as a flashlight's light diminishes with distance, the apparent brightness of a star decreases as it moves farther away from an observer. If two stars have the same absolute magnitude but are at different distances, the one closer will appear brighter (higher apparent magnitude) than the one farther away. This relationship illustrates how apparent magnitude depends not only on intrinsic brightness but also on distance from the observer.
Is it possible for two regular stars to have the same absolute magnitude but differ in apparent magnitude?
One dimmer star can be closer than a brighter star that is far away. Light flux decreases as the square of the distance. A star that is three times as far away will have to shine nine times brighter than the closer star (absolute magnitude) to appear to have the same magnitude (apparent magnitude). Because apparent magnitude is the brightness of a star, as seen from Earth, whereas absolute magnitude is the brightness of a star as seen from the same distance - about 32.6 light years away.
What is the actual amount of light a star gives off?
It is actually absolute magnitude, opposed to apparent magnitude which is how much light stars appear to give off.
What does rigel have brighter then Sirius?
I'm not sure exactly what detail you want, but here's a start. Rigel is a triple star system. The main star of the three is a very luminous star. It is a blue supergiant star.

Does our sun have a lower absolute magnitude then Betelgeuse?
No, Betelgeuse has a lower absolute magnitude compared to the Sun. Betelgeuse is a red supergiant star with a much larger luminosity, making it appear brighter despite its greater distance from Earth.
Why 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 is the magnitude of a white dwarf?
The magnitude of a white dwarf can vary significantly, typically ranging from about 10 to 15 in absolute magnitude. This variation depends on factors such as its mass, temperature, and composition. For example, hotter and more massive white dwarfs tend to have lower absolute magnitudes, making them appear brighter. However, their apparent magnitude can differ based on their distance from Earth.
Even though this star has an absolute magnitude greater then that of sirius it looks dimmer from earth since it's 100 times farther away?
Yes, the star with the higher absolute magnitude will appear dimmer from Earth if it is located farther away. This is because brightness decreases with distance due to the inverse square law of light, meaning that a star will appear dimmer the farther it is from the observer.
What can be said about the absolute magnitude of two equal-sized stars whos colors are blue-voilet and orange-red?
Absolute magnitude refers to a measure of the real brightness of a star. In terms of absolute magnitude, a blue-violet star is classified as bright, while an orange-red star is classified as faint.
What is the actual amount of light a star gives off?
It is actually absolute magnitude, opposed to apparent magnitude which is how much light stars appear to give off.
What is the relationship between luminosity and absolute magnitude in stars?
The relationship between luminosity and absolute magnitude in stars is that luminosity measures the total amount of energy a star emits, while absolute magnitude measures the brightness of a star as seen from a standard distance. Stars with higher luminosity have lower absolute magnitudes, meaning they appear brighter in the sky.
