Answer:
56N
Explanation:
Given parameters:
Distance = 40m
Work done = 2240J
Unknown:
Force exerted = ?
Solution:
The work done on a body is the force applied to move a body through a certain distance.
Work done = Force x distance
Now insert the parameters and solve for the force
2240 = Force x 40
Force = 56N
Answer: 0.078
Explanation:
Given variables:
R1 = 25.0 , R2 = 64.0 , I1 = 0.200
Step 1: find V
0.200 = v/25
0.200 * 25 = v
5 = v
Step 2: Solve for I2
I = V/R
I = 5/64
I = 0.078125
