Q. Why do pieces of paper stick to a comb?
The paper is attracted to the comb. This happens because the charged comb induces an opposite charge in the paper and as opposite charges attract, the paper sticks to the comb.
Q. Why do bits of paper attracted on the hair comb and stick to it for a while what type of electricity attracted the bits of paper to the hair comb?
ANSWER: The paper is initially attracted to the comb because the comb causes separation of charge in the paper. The part of the paper pieces with positive charge is attracted to the comb. When the paper touches the comb, some of the excess negative charge in the comb is transferred to the paper.
Q. What do you think made the bits of paper reacted the way on the comb?
This is because the comb gets charged when it is rubbed. Within the papers strips, the electrons get either repelled or attracted according to whether the comb has a negative or a positive charge. This makes the paper strips have an unlike charge in the direction of the comb, and makes them rise towards it.
Q. What happened to the bits of paper place near the comb after using?
Answer: The first time you brought the comb near the paper bits, nothing happened, but when you combed your hair, you gave the comb a charge of static electricity Then, when you brought the comb near the paper bits, they were attracted to the comb because of this charge.
Q. What happens when you rub a comb on a piece of wood?
The comb gains electrons. …
Q. What happens when you brought the comb near the stream of water did it bend?
When the comb ran through your hair, it picked up negatively charged electrons from the hair. This caused the atoms of the comb to have a negative charge. The stream of water had a positive charge, so it was attracted to the negatively charged comb and bent in it’s direction.
Q. What happens if you place the charged comb on the other side of the stream of water?
The charge on the screen attracts dust. The comb attracts the stream of water in the same way. The charge on the comb attracts the molecules of water in the stream. Because the molecules in the stream can be moved easily, the stream bends toward the comb.
Q. What happens when two objects are charged by contact?
– occurs when two objects are rubbed together and electric charges are transferred from one to another. -one material will gain electrons while the other will lose electrons. – electrons will move from one object until the other until the charge evens out.
Q. Is charging by contact permanent?
A negatively charged object has electrons that are transferred to the other object. There is contact, the negative conducts a negative charge, and it is permanent. Permanent because electrons do transfer and stay on the newly charged object.
Q. What is charging by induction and how does it occur?
In the induction process, a charged object is brought near but not touched to a neutral conducting object. The presence of a charged object near a neutral conductor will force (or induce) electrons within the conductor to move. The flow of electrons results in a permanent charge being left upon the object.
Q. When hair sticks to your comb as it is being combed This is a result of?
When hair sticks to your comb as it is being combed, this is a result of charging by conduction.
Q. When something is grounded what happens to the excess electrical charge?
Grounding is the process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size. When a charged object is grounded, the excess charge is balanced by the transfer of electrons between the charged object and a ground.
Q. Can positive charges be grounded?
We can consider the grounding of a positively charged object. By gaining electrons from the ground, the object will have a balance of charge and therefore be neutral. Grounding is the grounding of a positively charged object and involves the transfer of electrons from the ground into the object.
Q. What would happen if a negatively charged rod were touched to the neutral metal doorknob?
If you then reach out to touch a metal doorknob, electrons in the neutral metal will be repelled and move away from your hand before you even touch the knob. The electrons move away from the rod, causing one side of the plate to become positively charged and the other side to become negatively charged.
