12. why could Newton not determine the magnitude of the G with his equation? (this question I don't understand?

Answer 1

1. What is Newtons First law?
6. correct.
9. No, you have to say force= something. your answer is what the something is.
12. He didn't have enought time, Cavendish finally did it. It is not an easy task measuring the attraction due to small masses.
