in which spectral class does a white dwarf with a temperature of 10000 k belong?
(1 point)
○ b
○ a
○ o
○ f

Explanation:

Locate 10,000 K on the temperature axis of the H-R diagram. This temperature aligns with the spectral class A, and the white dwarf data points at this temperature fall under class A.

Answer:

A. A
