Which of the following statements about degeneracy pressure is not true? a)degeneracy pressure can halt gravitational contraction of a star even when no fusion is occurring in the core. b)degeneracy pressure keeps any protostar less than 0.08 solar mass from becoming a true, hydrogen-fusing star. c)degeneracy pressure varies with the temperature of the star. d)degeneracy pressure is a consequence of the laws of quantum mechanics.

C)Degeneracy pressure varies with the temperature of the star.

Explanation:

Pauli exclusion principle states that no two electrons can occupy same states. Thus, the gravitational collapse of a massive star is halted due to degeneracy pressure where at high temperature, the electrons occupy higher energy levels and this pressure balances the gravitational contraction. This degeneracy pressure does not depend on the temperature. It depends on the density of the fermions only.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

joke:

h o h o hope you have a merry christmas!

can somebody give me the answer so i can graduate
