Mechanism behind charging the communication

Describe exactly the mechanism behind charging the comb. Is it conduction, friction, or induction? Which ways do the electrons travel? 4. Lay the small pieces of materials/objects on a level surface, and bring the comb close, without touching. In the case with running water or your arm/leg, make the comb almost (but not quite) touch them. Describe the interaction in the first three columns of the table below. You are welcome to add extra rows if desired. 5. In the last column of the table, describe in as much detail as possible what happens with the charges in the objects/materials you picked. Hint: think of polarization, charge transfer, induction, etc
