Answer:
The second arrow from the top to the bottom
Explanation:
This can be explained by the Newton's third law.
For every action there is an equal and opposite reaction.
When an object A exert a force to an object B. Then object B also excerts a force with the same size but opposite direction to object A.
I think it has 11 but i don't really know for sure.Correct me if i'm wrong.
Answer:
7. 2 kg
8. 0.5 kg
9. 4 kg
Explanation:
The equation is F=MA
where F is force in Newtons
M is mass in kg
A is acceleration in m/s^2
for each you substitute in the F and A, and you are finding M. Meaning you divide F by A.
M = F/A
6/3 = 2
6/12 = 0.5
20/5 = 4
it's joules per gram degree celsius
