Question

select the correct answer from the list. (1 point)
as a star’s size increases, its luminosity dropdown. as a star’s temperature dropdown, its luminosity increases.

Explanation:

Stellar luminosity follows the Stefan-Boltzmann law, which states luminosity $L = 4\pi R^2 \sigma T^4$, where $R$ is stellar radius (size) and $T$ is temperature. A larger radius (size) directly increases luminosity, and a higher temperature (raised to the 4th power) also increases luminosity.

Answer:

1. increases
2. increases
