question 10 (1 point)\nhow do scientists know that the sun is a middle - aged star?\nby its brightness\nby how fast it spins\nby its temperature\nby its size

Answer

Answer:

By its temperature

Brief Explanations:

The Sun's temperature and its position on the Hertzsprung - Russell diagram help scientists determine its age. Middle - aged stars like the Sun have characteristic surface temperatures. Brightness, spin rate, and size are less directly indicative of a star's age compared to temperature in this context.
