Calculate how many times the density of a star – a white dwarf – is greater than the density of the Sun. The volume of the Sun is a million times greater than the volume of a white dwarf; the masses of these stars are equal.
For equal masses, the ratio of densities is inverse to the ratio of volumes, i.e. the density of the white dwarf is 106 times that.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
