Answer:
F = 0.483 N
Explanation:
Initial momentum, 
Final momentum, 
Time, t = 31 s
We need to find the force of a lead ball. We can use here the impulse momentum theorem.

F is force

So, the force is 0.483 N.

The answer is B - Current Y has a greater potential difference, and the charges flow at a slower rate.
I just took the quiz
25/1500 is equal to 0.8/x
0.8*1500 is equal to 1200
1200/25 is equal to 48 N
It is an example of balanced force.
hope this helps. good luck
