I think the answer to this is 0.811nm
Answer:
12N to the right.
Explanation:
There is a force of 12N upwards and a force of 12N downwards: these cancel out.
Assign a negative value to forces towards the left, and a positive value to the forces towards the right: -3N and +15N
Combine them: -3N+15N = 12N
The net force has a magnitude of 12N, and since our answer was positive, it acts towards the right.
Answer:
C) scientist use experiments to test their ideas
Answer:

Explanation:
Initial angular speed of the player is given as

here we know that

now we know that


now its speed comes to zero in 0.2 s
so angular acceleration is given as
