Rubbing the comb and sweater together created static electricity, which gave the comb an electrical charge.
What form of energy is produced by the comb?
The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge. This “separation of charge” is the reason for the collection of effects we call static electricity.
What form of energy is produced when comb is placed near the dry?
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 happens when you rub a comb on a piece of wood?
We often comb longer with a wooden comb because it feels so good. The massaging action stimulates the follicles to produce more hair strands, increasing hair growth and producing thicker hair.
What happens when a comb is rubbed on dry hair?
When a plastic comb is rubbed against dry hair vigorously, then there is a transfer of charge taking place between the two. As a result, both objects become charged. While one becomes positively charged, the other becomes negatively charged. This is called charging by friction.
What are the forms of 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.
When a comb is rubbed in your hair it acquires?
Complete step by step answer:irstly, when the comb is used to rub dry hair, it always acquires a negative charge or electron which the hair carries, where the comb is induced with the electron gotten from the hair then immediately the comb which is negatively charged comes in contact with the piece of paper which is …
What form of energy is produced by the guitar?
The guitar uses electrical energy. The guitar produces sound energy when the strings are plucked.
When a comb is rubbed with dry hair it attracts pieces of paper because?
When a comb rubhed with dry hair attracts pieces of paper. This is because the comb induces a net dipole moment opposite to the direction of field. This happens the field due to charge on comb induces dipole moment in paper by tretching or re-orienting molecules of the dielectric.
How do you make static electricity with a comb?
Comb vigorously! Comb everyone’s hair! On the vertical, bring the comb toward the water (but don’t touch the water) and the electricity you just generated with the plastic comb and your hair should cause the water to bend toward the comb. You may need to try it a couple of times to get it to work.
What type of electricity attracted the bits of paper to the comb at first?
You can observe static electricity if you run a plastic comb through your hair, then place the comb near small pieces of paper. 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.
How is static energy produced?
Static electricity can be created by rubbing one object against another object. This is because the rubbing releases negative charges, called electrons, which can build up on one object to produce a static charge. … You can suddenly discharge the static charge as a shock when you touch a friend or some objects.
Does the material that the comb is made of affect the static power?
A hard rubber or plastic comb will collect negative (−) charges on its surface. Since similar charges repel, the hair strands will push away from each other, especially if the hair is very dry. … Since the comb is negatively charged, it will attract object with a positive charge—like hair.
What happens when we comb our hair?
Combing activates your sebaceous glands, the little guys at your hair roots that produce your scalp’s natural oil (sebum). Along with keeping the scalp and hair moisturized, sebum coats the scalp surface and work to create the right pH balance, which is very important for healthy scalp.
How does a comb become positively charged?
The molecules orientate their dipoles, the negative oxygen towards the comb; the positively charged hydrogens away from it. When you comb your hair with a nylon comb, both the comb and your hair become charged. The comb and your hair acquire opposite charges.
When a comb is rubbed with dry hair both comb and paper get similarly charged?
Correct: A comb rubbed with hair and brought near pieces of r paper attracts them, because both have dissimilar charges.
