The Interiors of White Dwarfs Are Characteristically

question 239

Multiple Choice

The interiors of white dwarfs are characteristically:

• A) mainly carbon and oxygen nuclei supported by electron degeneracy pressure in a volume about the size of the Sun.
• B) mostly hydrogen nuclei supported by normal gas pressure due to the very high gas temperature, in a volume about the size of the Earth.
• C) mainly carbon and oxygen nuclei supported by electron degeneracy pressure in a volume about the size of the Earth.
• D) mainly helium nuclei supported by electron degeneracy pressure in a volume with a radius about 11 times that of the Earth, about the volume of Jupiter.

Sedges

A family of grass-like plants, often found in wet grounds, distinguished by their edges (edges, sedges) and triangular stems.
