When a person combs her hair static electricity is sometimes generated by what process?
friction between comb and hair resulting in flow of electrons.
Why when I comb my hair I hear static?
As the nylon comb has been stroked through the hair, electrons from the hair have moved to the comb. Hair will be pulled out by the comb because the comb will gain an negative charge and the hair, having lost its electrons is left with a positive charge.
Can combing your hair create static electricity?
You can observe static electricity if you run a plastic comb through your hair, then place the comb near small pieces of paper. … When a comb is run through your hair charges pass between your hair and the comb, so the comb becomes charged either positively or negatively, and the hair oppositely charged.
When a comb is charged negatively by running it through your hair the hair is?
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. If two objects have different charges, they attract (or pull towards) each other.
Which of the following is an example of static electricity?
What are three examples of static electricity? (Some examples might include: walking across a carpet and touching a metal door handle and pulling your hat off and having your hair stand on end.) When is there a positive charge? (A positive charge occurs when there is a shortage of electrons.)
Is a balloon an insulator or conductor?
Objects made of rubber, such as the balloon, are electrical insulators, meaning that they resist electric charges flowing through them. This is why only part of the balloon may have a negative charge (where the wool rubbed it) and the rest may remain neutral.
What causes hair static?
What causes static hair? Static hair occurs when your hair builds up an electric charge, meaning it has gained some extra electrons thanks to friction or a change in humidity. … Plus, the elements, a lack of moisture in the air, and heated indoor environments can all exacerbate static hair.
How do salons reduce static electricity?
Wire hanger: Glide the long side of a wire or metal hanger over your clothes to remove static electricity. Lotion: After a shower or bath, add moisture to your body. The lotion will act as a barrier and prevent static electricity from building up. Rub lotion on your hands, legs and even a small amount to your hair.
What causes static electricity?
Static electricity is created when positive and negative charges aren’t balanced. … When an object (or person) has extra electrons, it has a negative charge. Things with opposite charges are always attracted to each other, so positive charges seek negative ones and negative ones seek positives.
What is a static comb?
After a plastic comb is used for straightening dry hair (or rubbed on wool) it becomes electrically charged. The charge creates an electric field which then induces charge separation in the nearby paper bits thus leading to a net electrostatic attractive force between the bits and the comb.
What must be done to a comb in order for it to produce static electricity?
A comb is charged with static electricity by combing hair. … Rather than completely freeing (ionizing) electrons from the paper’s atoms and molecules, the E field from the excess electrons on the charged comb displaces the positive and negative charges away from their neutral position.
When you comb your hair with a plastic comb which object the hair or the comb holds on to its electrons more tightly What is the charge on this object?
hair is weaker at holding onto its electrons. So the hair would have a positive charge.
Why does a comb become negatively 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. … This is a result of your hairs repelling each other because they are charged.
Does the size of the comb affect the static power?
Remember that, its important. Now that the comb has a negative charge, it is attracted to things that have a POSITIVE charge. … If the pieces are small enough they will jump off the table to the comb the same way that the water was pulled to the comb.It is all thanks to the wonders of static electricity.
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.
