This is because the neutrality of polarity can be changed by electric field in this case. When you create – charge in the comb and you expose the pieces of paper to the electric field created by the charge, you will polarise them so that the part closer to the comb will be + and the other will be -.
What form of energy is formed when comb is placed near the dry bits of paper?
What happens now? What Happened: 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.
What form of energy is produced when comb is placed?
Rubbing the comb and sweater together created static electricity, which gave the comb an electrical charge. The electrical charge is what drew the water towards the comb.
What happens to the bits of paper when the plastic comb was placed near them?
You can observe static electricity if you run a plastic comb through your hair, then place the comb near small pieces of paper. … This happens because the charged comb induces an opposite charge in the paper and as opposite charges attract, the paper sticks to the comb.
What form of energy is found at the end of the matchstick How does energy transformation occur in a lighted candle Brainly?
When the match is struck, it burns and the chemical energy in it produces heat energy and light energy. Candles also possess a lot of chemical energy.
Can you lift the bits of paper with the plastic comb?
When the comb is rubbed on a dry cloth, it gets electrically charged. This charged comb exerts an electric force on the tiny pieces of paper and attracts them. Initially the comb is electrically neutral. So it has no effect on the tiny pieces of paper.
Why is paper attracted to a charged rod?
A positively charged rod is brought near a piece of paper. … When the positively charged rod is brought near the neutral paper, it induces a negative charge on the side of the paper nearer to the rod. Since unlike charges attract each other, the paper will be attracted to the rod.
Which of them has stored energy?
Stored energy can have many forms, including gravitational potential energy, pressurised gases and liquids, stored mechanical energy, and stored electrical energy.
What is forms energy?
Energy exists in many different forms. Examples of these are: light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy and so on. Each form can be converted or changed into the other forms.
Why would torn paper be more attractive to the comb?
Charge accumulates more easily on sharp points rather than edges. Torn pieces of paper have more sharp points (look at it under a magnifying glass, or better yet, a microscope!) compared to cut paper.
Can you lift the bits of paper with the plastic comb why Brainly?
The comb is electrically neutral so it has no effect on the tiny pieces of paper. When the comb is rubbed with dry hair, then it gets electric charge. This electrically charged because comb exerts an electric force on the tiny pieces of paper and attracts them.
Why can a plastic comb attract tissue paper?
For example, a negatively charged plastic object such as a comb or ruler repels electrons in a piece of paper. The near side of the paper to the plastic object becomes positively charged, so it is attracted to the plastic object.
