What is the mass to light ratio of a 10 M Sun white dwarf with luminosity of 5x10 3 L Sun?
That is an oddly phrased question.
If you're looking for the mass to luminosity relationship, it's generally L = M^3.5.
But your question asks for the mass to light ratio. I'm not sure what the "light" part is referring to. But as you are given the luminosity, and the mass, perhaps you mean the ratio between those two quantities? Then you just do some division to create a ratio...

What type of star has a high temperature and a high luminosity in the hr diagram?
White dwarfs.
What color is the star lesath?
It is a white dwarf.
What planet is closest in mass to a white dwarf?
A white dwarf who's progenitor star was about the same mass as our Sun will leave behind a stellar remnant around the size of our Earth. Obviously if the progenitor star was larger or smaller, then the stellar remnant will also be larger or smaller.
What is the luminosity of a white dwarf star?
The luminosity of a white dwarf star can vary depending on its mass and age, but typically ranges from about 0.001 to 0.1 times the luminosity of the Sun. These stars are small and dense, with surface temperatures ranging from 8,000 to 100,000 Kelvin, which affects their brightness.

How is it possinle for whit dwarfs to have a lower luminosity than the sun even though the sun is much cooler than the white dwarf?
Luminosity will also depend on the surface area. The Sun has about 10,000 times the surface area of a typical white dwarf.
Why do you think the size of a white dwarf affects its visual luminosity?
The size of a white dwarf affects its visual luminosity primarily due to its temperature and surface area. While white dwarfs have a consistent mass range (around 1.4 solar masses), their size can vary based on their composition; a smaller radius typically means a higher density and temperature. A hotter, denser white dwarf emits more thermal radiation, resulting in greater luminosity. Thus, even slight variations in size can lead to significant differences in the amount of light emitted, impacting its overall visual brightness.
How does a white dwarf produce light and heat?
There is no source of energy heating a white dwarf. The heat is left over from when it was a full-fledged star, like a stone pulled from the coals of a fire. The white dwarf glows simply because it is very hot.
Do all star have the same light? why or why not?
No. Stars of different sizes and composition have different luminosity (light) levels. A very big star will most likely be blue and shines very brightly, while small stars like white dwarf stars emit very white light, but are mostly very dim.
Why do white dwarfs have low luminosity?
even though a white dwarf may burn hot, it's size is what limits it's luminosity. Here is one way to look at it: Imagine a white dwarf with the mass of our sun. Our sun's surface temp is right around 5,770K and weighs one solar mass. Now, this imaginary white dwarf would be about the size of the earth and have a surface temp of around 10,000K - 11,000K. This white dwarf would have a surface area 1/333,000 of the sun. A white dwarf of this size is about average and as you can imagine, has very little room to put out energy compared to other solar masses.
