Question

absolute properties that belong to the star _______ and do not involve _____. the first property well talk about is luminosity, which can be described as the _____ output of the star. luminosity depends on two things: the first is how much _____ is radiated in a given area per second, and the second is how much _____ _______ the star has, or essentially how big the star is. you can see that a small star that is very intense could give the same total output as a large star with a lower output. this is due to the fact that the smaller star is stronger than the larger star.
1.7 absolute properties - 2
another inherent property of stars is their absolute _______, or absolute _____. this absolute magnitude then, is the brightness of a star at that _____ distance. by establishing a _______ distance, we can then compare one star to another very easily.
1.9 apparent properties - 1
if you move a star far _______ from your hand it feels _____ intense, and if you bring it _____, it feels _____ intense. now imagine two stars that are exactly the _____ except one is close to your hand and one is very far away. notice that nothing is different about the two stars, yet one will _____ to be stronger than the other due to its proximity to your hand. this is an example of the _____ brightness, or simply what you see from _____ you are. the two stars are the same, so the _____ magnitude will be the same, but due to their _____, they will _____ different. thinking about our sun, there are much stronger stars out there, but because they are so _____ _____, they will never be as bright as our _______ sun.
1.11 apparent properties - 3
many of the stars we see in the sky appear to be about the same, even though some are huge and bright, while others are small and dim. in reality, the stars are positioned at many different _______ from earth and each burns with a different intensity. from these different scenarios, we can see that the way a star in the night sky _____ to us depends on the _____ of the stars themselves, but also their _____ and their _______ relative to ours.
1.12 practice 3 match the definitions on the right with the correct term for star brightness.
absolute brightness how bright a star looks from a standardized distance
apparent brightness how bright a star looks from earth
luminosity the total energy output of a star
1.13 apparent vs. absolute - 1

Explanation:

Answer:

1.7: magnitude; brightness; standard; standard
1.9: away; less; closer; more; SAME; appear; apparent; where; absolute; distance; look; far away; local
1.11: distances; appears; luminosity; size; distance
1.12: Absolute Brightness - How bright a star looks from a standardized distance; Apparent Brightness - How bright a star looks from Earth; Luminosity - The total energy output of a star
