Consider the indicated events in the history of the universe that have make human life possible. rank the events based on when they occurred, from longest ago to most recent. to rank items as equivalent, overlap them. note: if two events occurred within seconds of each other, rank them as equivalent.
- the big bang & the universe begins to expand
- elements such as carbon and oxygen first exist
- nuclear fusion begins in the sun
- earliest life on earth
- dinosaurs go extinct
- earliest humans

explained

Explanation:

1. the Big Bang & the universe begins to expand  - about 13.8 billion years ago

2.  elements such as carbon and oxygen first exist - 8 billion years before.

3.nuclear fusion begins in the Sun - Our sun is 4.603 billion years old

4. earliest life on Earth - Earth formed in early September on the cosmic calendar. Life apparently arose on Earth within less than a billion years after that, which means it was still in September (because each month on the cosmic calendar represents about 1.2 billion years).

5.dinosaurs go extinct - 65 million years ago

6. earliest humans- 40 million years ago

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
