The Hertzsprung-Russel diagram is used to show the relationship between which two characteristics of stars? A. Luminosity and temperature
B. Mass and luminosity
C. Temperature and mass
D. Mass and color

A

Explanation:

absolute magnitude and luminosity vs the spectral position/ temperature

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
