Do the stars on the main sequence illustrate the mass-luminosity relationship?
Luminosity depends directly on mass because more massive main-sequence stars do not need to graviationally contract as far to reach fusion temperatures, and so they have a larger volume and contain a much larger amount of light energy, which diffuses out and generates a higher luminosity, very roughly in proportion to the higher volume.
What affects the luminosity of a star?
The total amount of light that the star radiates each second.
What luminosity measure that different from what absolute visual magnitude measures?
1.Luminosity is the amount of light emitted from a certain light source whereas brightness is the amount of light manifested or received. 2.The area of illumination is inversely proportional to brightness whereas luminosity isn't. 3.Brightness is usually expressed in 'Lumens' whereas luminosity is expressed in candela per square meter (photometry).
How much would the earth weight on a scale?
Earth's mass is 5,973,600,000,000,000,000,000,000 kg.
Which star would live longer a star that has half the mass of the sun or a star that has 2 times the mass of the mass?
Stars with less mass live much longer. Stars with greater mass get hotter, and have more pressure in their core; as a result, they use up their fuel much faster.

How much gallons of water fall over in Yosemite falls a day?
3160 tons every second
What is the formula for a stars life?
The life of a star is governed by how much mass it has and how quickly it "burns" it. A basic formula is 1exp10*(m/l) where m=Sol mass and l=Sol luminosity. So for our Sun 1exp10*(1/1) gives 10 billion years.
How do astronomers measure stellar luminosity?
The reference that astronomers use to compare the luminosity of other stars is the sun's luminosity. The luminosity is denoted in multiples of the sun's luminosity. For example, the luminosity of the star Sirius is 25 times the luminosity of the sun.
How much percentage would the mass be if Ceres would suddenly leave the asteroid belt?
The mass would not change!
Mass of aluminum chloride?
The mass depends on how much you use but the molecular mass would be 160.31gmol as it is Al2Cl3.
How much brighter than Sirius would the Betelgeuse supernova be in your sky if it reached a maximum luminosity?
The supernova would be so much brighter that it's hard to compare, at least 10 magnitudes brighter then Sirius. It would probably be about the same brightness as the full moon in the sky.
What is 395 times 8?
It is 3160. You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer.
Is an AGN a compact region at the center of a galaxy that has a much higher than normal luminosity?
Yes, an AGN is a compact region at the center of a galaxy that has a much higher than normal luminosity, over at least some portion, and possibly all, of the electromagnetic spectrum.
Which would you measure first mass or volume and why?
mass, then you can see how much space it takes up
Would a mass of a solid of g have same weight on earth?
Mass and weight are two separate things. Mass is how much an object contains. Weight is how the mass is affected by gravity. To answer your question, no, it would not.
