Explanation / Answer
1) A thousand years after the big nag what was present in the known universe?
ANSWER:BCDF,B-Free muons C-Free electrons d- Free electrons e Photons F-Competely ionized hulium
a thousand years after the big nag what was present in the known universe beacause at the old universe only elecrons and photons are mainly working..
2)Which of the following are present in large amounts at about a billion years after the bang? Select all that are correct.
ANSWER:B. ce ie.c.) free muons e) free protons
3)When did large amounts of neutral atoms begin to accumulate in the universe?
ANSWER:B. Second after the bang
the history of amounts of neutral atoms begin to accumulate in the universe is B. Second after the bang
4)When did large amounts of compleltely ionized heliumnuclei begin to accumulate in the universe?
ANSWER:A microsecond after the bang,large amounts of compleltely ionized heliumnuclei begin to accumulate in the universe is microsecond after the bang.
