Answer:
This is due to the gap in between the switch. So the applied energy is not converted to current even though the resistance is still there. Hence voltage will be there, where you applied it
Explanation:
Answer:
F = 0
Explanation:
Given that,
Force acting to push a bin = 45 N
Mass of the plastic bin, m = 3 kg
The plastic bin is moving with a constant velocity.
We need to find the net force acting on the box. Constant velocity means the change in velocity is equal to 0. It means acceleration will be 0.
As a result, the force acting on the box is equal to 0.

Explanation:
i dont know how to help you with this one. I dont even know what the problemk is asking
The pendulum <u>will not strike the wall. </u>This is because of the principle of conservation of energy.
The pendulum is released close to a wall with no initial velocity. At the point of release, the pendulum has no kinetic energy, but has a potential energy E. This potential energy is converted into kinetic energy, when it reaches the mean position. The pendulum then swings to the other side and it stops momentarily at the other extreme position, when its kinetic energy is converted into potential energy. It then begins its return swing.
If no energy is lost during the oscillation of the pendulum, when it reaches the position where it was released, its kinetic energy would be entirely converted into potential energy. Therefore, when it reaches the point close to the wall, where it was released,it would have zero velocity. After this point, the pendulum turns back due to the restoring force acting on it, which is directed towards the mean position.
To travel further and strike the wall, it needs more kinetic energy, which is not provided to it. Hence it would never strike the wall on its return swings.
