Approximately, what basic composition are all stars born with?

Question

a)one-quarter hydrogen, three-quarters helium, no more than 2 percent heavier elements
b)90 percent hydrogen, 10 percent helium, no more than 1 percent heavier elements
c)98 percent hydrogen, 2 percent helium
d)half hydrogen, half helium, no more than 2 percent heavier elements
e)three-quarters hydrogen, one-quarter helium, no more than 2 percent heavier elements

Answer 1

B is the closest.
The initial composition of stars varies, depending on the abundance of heavier-than-helium elements in the nebula from which the star formed. So B is more like an average.

Answer 2

3/4 hydrogen 1/4 helium, reference The Cosmic Perspective 7th edition.

Answer 3

You know, if people would just READ a few things once in a while, they would learn a lot without having to cheat on their homework by getting the answer from someone else.
Looking at someone's test answers, text-messaging answers during class, or using Yahoo Answers is all the same - its cheating. It may make things easy now, but you're in for a huge surprise when you get out into the real world and find that life doesn't let cheating slide.

Answer 4

Sounds like a homework question but I'll answer it so maybe you'll remember when it's on a test. The answer is b). You can believe me because I took astronomy classes in college and have been an amateur astronomer for 35 years.

Answer 5

It would have to be B, most stars are made with some sort of heavy elements involved, their would be some.

Answer 6

The answer is E, not B.

Answer 7

B
