If you comb your hair, for example, electrons leave the atoms and molecules in your hair and travel to the plastic comb. The comb, covered in negatively charged electrons,
becomes negatively charged as well
, and your hair is left with a positive charge.
When I comb my hair with a plastic comb on a very dry day why does my hair stand up?
When your hair is dry, especially after washing it and using a hair dryer, the various strands of hair may stick up and spread apart when you try to comb it. The reason is because
the dry hair tends to collect positive (+) electrical charges when combed
with a plastic comb.
What happens when you rub plastic comb on your hair?
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.
When people pull plastic combs through their hair?
Like the rod with fur, when the comb is pulled through hair,
it acquires a negative charge
. … Another example of this the common trick of rubbing a plastic balloon in someone’s hair. After being rubbed together, the plastic in the balloon picks up a negative charge, while the person’s hair ends up with a positive charge.
When you comb your hair with a plastic comb what type of charge does your hair acquire in the process?
Because opposite charges attract, the two pieces of tape attract each other. When you run a plastic comb through your hair, the comb becomes
negatively charged
. Tapes repelled by the comb have a net negative charge, and tapes attracted by the comb either have a net positive charge or are uncharged.
When you rub a plastic rod against your hair?
Answer: a)
both get opposite charge
. Explanation: When you rub plastic with your hair it get charge through process of conduction ,and when you put near some bits of paper the paper get opposite charge through induction.
What are 3 examples of static?
Have you ever rubbed a balloon on your head and made your hair stand up? Have you ever walked across the carpet in your socks and received a shock from a doorknob
? These are examples of static electricity.
What happens to the comb when dry hair is combed?
Answer: When the comb runs through dry hair,
it gets charged by friction
. The molecules in the paper get polarized by the charged comb, resulting in a net force of attraction. If the hair is wet, or if it is a rainy day, the friction between the hair and comb reduces.
What happens when you bring the balloon near your hair after rubbing it?
Rubbing the balloon onto your hair or onto the wool fabric adds electrons to the balloon and
causes the balloon to become negatively charged
. … Your positively charged hair is attracted to the negatively charged balloon and starts to rise up to meet it.
How can I hydrate my hair?
Use
cold or tepid water
instead, of hot water when washing hair. Cold water helps to seal the cuticles and reduces moisture loss. Use moisturizing shampoo and conditioner, such as those with softening oils that can include sweet almond, Argan, sunflower, and soybean.
Why does a comb get negatively charged?
How does it work? When you brushed that comb through your hair, tiny parts of the atoms in your hair, called ELECTRONS, collected on the comb. These electrons have a NEGATIVE charge. … Now that the comb has a negative charge,
it is attracted to things that 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.
Is a plastic comb a conductor?
The pieces of straw attracted to polished amber are neutral, for example. If you run a plastic comb through your hair, the charged comb can pick up neutral pieces of paper. … (c)
The same effect occurs for a conductor
; since the unlike charges are closer, there is a net attraction.
Why would a balloon attract your hair without touching it?
Hold the balloon (negatively charged) just above your head
so your hair (positively charged) will be attracted to it and stand up on end. … The can will start to roll towards the balloon without touching it. The negatively charged balloon repels the electrons of the can so that a positive charge is near the balloon.
Why does the hair become positively charged?
Whenever atoms rub up against each other, electrons can transfer between them. …
When you rubbed the ballon in your hair, electrons moved from the atoms in your hair into the atoms in the balloon
, making your hair positively charged and the balloon negatively charged.
Why do balloons get a total negative charge when rubbed on hair?
Rubbing the balloon against hair or wool causes electrons to move from the hair or wool to the balloon.
Because electrons are negatively charged
, the balloon acquires a net negative charge. The balloon’s negative charges are attracted to the positive charges in the can, and so the can rolls toward the balloon.
