The graph below plots the temperature and luminosity of stars on the main sequence. (2 points)

Four locations (A, B, C and D) are graphed on a curve representing luminosity vs temperature. The curve begins are high luminosity and high temperature decreasing in luminosity and temperature as it approaches the right side of the curve. From left to right are points representing Location A, Location B, Location C and Location D.

At what location is the star with the least initial mass most likely to be found?
Location A
Location B
Location C
Location D

Answer:

location A

Explanation:

What is the flaw with using apparent brightness rather than absolute brightness to determine the brightness of a star?

Apparent brightness does not use the star's color or temperature.

Apparent brightness does not take into account the distance of the star from Earth

Apparent brightness is only theoretical, its value cannot be directly measured with equipment

Apparent brightness is only on a comparative scale that determines how bright a star looks from a theoretical distance of 10 parsecs
from Earth.
