the --- of a star determines its temperature and luminosity. A. density. B. mass. C. location. D. width

Answers

Answer 1
Answer:

Answer:

Option B, Mass

Explanation:

The general relation that gives the relationship between the lumonisity of a star and its mass is

L \alphaM^(3)\n

Thus, suppose if the mass of any star is two times the mass of sun then its luminosity will be 100 times the luminosity of sun.

The general relation between luminosity and temperature is

L\alpha R^(2) T^(4) \n

Since luminosity is depended on mass, and temperature is dependent on luminosity , thus it can be said that temperature is also dependent on mass of a star.

Thus, option B is correct.
Answer 2
Answer: b. mass
stars support their weight by making more energy which means more luminosity.
