Answer: B 2V
Explanation:
Since the voltage of the battery is 2V.
At point A and B, there is no voltage drop. So the voltage will still be same as in the battery which is 2V.
Answer:
308 J
Explanation:
The work done by a force applied parallel to a displacement is given by:
where
F is the magnitude of the applied force
d is the displacement
In this problem, we have
F = 22 N is the force applied
d = 14 m is the displacement of the wagon
Therefore, assuming that the force is parallel to the displacement, the work done is
Answer:
<u><em>Frictional force refers to the force generated by two surfaces that contacts and slide against each other.</em></u>
