What correctly describes the relationship between the luminosity of two stars that have the same radius?
The star that is hotter will have a higher luminosity.
How do you measure the distance to a cepheid?
Cepheids have a certain relationship between their period, and their absolute luminosity. Thus, their absolute luminosity can be determined. Comparing this with their apparent luminosity allows us to calculate their distance.Cepheids have a certain relationship between their period, and their absolute luminosity.

Relationship between stars distance to earth and luminosity?
Generally speaking, the apparent luminosity would be an inverse square relationship, which is to say, if the same star was at twice the distance, a quarter of the light would be reaching the observer. But absolute luminosity can of course vary without regard to distance from Earth - dim stars can be close, or bright stars distant, or vice-versa.
What diagram graphs types of stars?
I believe you are thinking of a Hertzsprung-Russell diagram, but this denotes the relationship between a stars luminosity and it's spectral class.It has nothing to do with the life cycle of a star.See related questions for more information
What type of relationship is shown on a HR diagram?
It is a chart showing a scatter chart of stars according to their temperature and their luminosity (or absolute magnitude).

What is the rleationship between luminosity and tempeature for stars on the main sequence?
On a logarithmic scale for luminosity, it is quite close to a negative linear relationship.
Which statement describes the general relationship between temperature and luminosity of main sequence stars?
as surface temperature increases, luminosity increases
What does the HR diagram depict?
the relationship between a star's luminosity, temperature, absolute magnitude, and spectral type.
What is the use of Hertzsprung Russell diagram?
It shows the relationship between stars luminosity versus their classifications and effective temperatures

What is the significance of the mass-luminosity relationship?
The mass/luminosity relation is important because it can be used to find the distance to binary systems which are too far for normal parallax measurements.
What was the scientist Henrietta leavitt famous for?
She discovered the period luminosity relationship of cepheid variables
How can the mass-luminosity relationship be used as a tool?
The greatest lover in Kansas is Jory Swogger
What is the general relationship between the temperature and the luminosity of main sequence stars?
The scatter plot of the relationship between a star's temperature and luminosity is represented by the Hertzsprung-Russell diagram. In a standard H-R diagram the horizontal axis shows the [surface] temperature, increasing from right to left, while the vertical axis shows luminosity increasing from bottom to top. When both axis are on a logarithmic scale, the main sequence stars from a diagonal belt stretching from top right (very hot and very luminous) to bottom left (not so hot and not so luminous).
