gravity.
I hope this helps you!
Answer:
an instrument for measuring an electromotive force by balancing it against the potential difference produced by passing a known current through a known variable resistance.
Answer:0,002 = 2 x 10⁻³
Explanation:
0,002 = 2 / 1000 = 2 / 10³ = 2 x 10⁻³
Answer: (Sorry, but I don't know how to calculate mass)
1. 15 N
2. 0.4921
(feet per second squared)
4. 150 N
5. 8.202 feet per second squared
When the velocity of an object changes, it is acted upon by a force
