The mass of the star actually determines the stage of the star after supernova. If the mass of the star is small, then it would become a very small and dwarf, cold and dead body in space. The mass of the star has to be less than that of the sun. If the mass of the star is greater than sun, then it would become a black hole. The mass of the star has to be more than 1.4 times the mass of the sun to become a black hole.

Answer:
A total number of people within a continent
Explanation:
The population growth in a particular place is reflective of how the population is changing positively over a period of time.
It is simply the change in population with with time.
- The total population through a given time frame and within a geography is very important for population studies.
- The population growth formula is given as:
P = P₀ eᵇⁿ
P is the total population
P₀ is the starting population
b is the growth rate
n is the time
