Answer:
Movement of electrons
Explanation:
when electrons move from a point to another, they carry along charges in the course of moving. Charges could be through metallic objects and as well could be through some conducting solution.
That leads us to Ohm's Law : it states that current flowing through a metallic conductor is directly proportional to the potential difference across its ends, provided that temperature remains constant. So for charges to flow through a conductor, there are factors to be considered.
The meter amount , and a pencil probably
Assuming that the box is moving when it is being pulled, Work is done on the box.
So work is the Force times the distance
W=Fd
But what is work actually ? When something moves due to force over some change in distance, it have energy.
But where does this energy come from ? Does it magically appear ? The energy comes from the applied force onto the box.
So the energy have been transferred. And it’s like that throughout the universe
Now to save time, I’ll just tell you the answer: kinetic energy
:)
Compressional wave! this is because you are compressing the spring coils together, thus creating a compressional wave!
The induced voltage is proportional to the time derivative of the net magnetic flux density. This is called faradays law of magnetic induction. Because you have a north and a south pole right next to each other (assuming they are magnets of equal strength) the total net magnetic flux will be zero. This is because the north end of one magnet adds a positive flux while the south end of the other magnet contributes negative flux.
As a result, the induced EMF will be zero. (I'm almost done with my PhD in electromagnetics engineering, so you can take this answer to the bank :) )
