6 where are main sequence stars located on a hertzsprung-russell diagram?
across the upper part of the diagram
across the lower part of the diagram
in a diagonal from upper left to lower right
in the center of the diagram
5/10 complete

Explanation:

The Hertzsprung - Russell (HR) diagram plots stars based on their luminosity (or absolute magnitude) and temperature (or spectral class). Main sequence stars, which include stars like our Sun, lie in a diagonal band that runs from the upper left (high - luminosity, hot stars) to the lower right (low - luminosity, cool stars) of the HR diagram. The other options are incorrect: across the upper part would be supergiants, across the lower part would be white dwarfs, and the center is not where main sequence stars are located.

Answer:

C. In a diagonal from upper left to lower right
