How do you explain why a charged comb often attracts smaller bits of papers that fly away when they touch the comb?
Static electricity in the comb attracted the slightly charged paper to it, but when the paper touched the comb, their very slight charge was neutralized, which caused them to fall off.
When you place a comb in bits of paper it does not stick but if you run the comb through your hair it sticks after combing your hair?
yesYou created a static electrical charge on the comb, causing it to attract the bits of paper.
Will a comb rubbed on the hair once attract bits of paper very they come close?
yes
Charging by friction eg?
When we rub the hair with a comb then charges could be produced on the comb. When this comb is taken near by a bit of paper then that piece would be attracted towards the charged comb.
Why do bits of paper adhere to a comb that was rubbed with a flannel cloth?
Because of a static charge caused by the rubbing.

Why can rubber rubbed with wool attract small bits of paper?
The reason why the pieces of paper are neutral is that they contain equal amount of positive and negative charges and so they cancel each other out. When you bring a charged plastic comb to the pieces of paper, the charge opposite to that of the plastic comb will be brought to a part of the surface of the paper where the plastic comb is. Opposite charges attract each other, and since you're holding the comb, the pieces of paper will be attracted to the comb.
Attractive comb can pick up bits of paper?
yes

Why do bits of paper adhere to a comb when rubbed w a flannel cloth?
because the come has chemical energy
Static electricity using comb and paper?
static electricity is caused by the attraction or repulsion of electric charges. surfaces have the ability to transfer charges to each other. when you comb your hair that is what happens. your hair gives the comb so electrons so now the comb isnegativley charged. when you put the comb near the paper, all the negative charges in the paper move away and te positive chrages move toward the comb,this makes the paper cling to the comb
Which type of force acts when tiny bits of paper are pulled by a rubber comb?
The force which acts is the electrostatic force.
Why a comb drawn through hair attracts a tiny piece of paper?
This is due to electrification process. As we rub the comb along with hair, the molecues in the comb would lose some electrons to the hair. This happens due to friction. So comb due to lack of negatively charged electrons becomes positively charged. Same time hair gaining electrons becomes negatively charged. Now as we keep this charged comb close to a bit of paper, then by electrostatic induction opposite charges here negative electrons are pulled towards it. So paper gets negative charge momentarily. Hence force of attraction between unlike charges. So paper bit gets attracted.
Does photo copiers use static electricity to copy on to a page?
Yes. The ink sticks just as a rubbed comb attracts bits of paper.
