Sally has a car that accelerates at 5 m/s2. If the car has a mass of 1000 kg, how much force does the car produce?

That depends on the gravity

Today, our atmosphere contains nitrogen, oxygen, argon, and carbon dioxide.

But back in the Precambrain time, it consisted only of nitrogen and carbon dioxide, lacking the oxygen.

Single celled organisms like like bacteria and viruses were abundant.

I do not know the last part of your question; I am unable to help.
