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.

Why does a comb drawn through hair attract a tiny piece of paper?
If a comb drawn through (dry) hair attracts a tiny piece of paper, it is almost certainly due to static electricity. We know that when some things are "rubbed" on other things, electrical charges can be displaced. A difference of potential is set up between two objects by moving charges from one object to another. And the difference of potential can, through electrostatic force, cause what is observed here.
How electrical energy converted into sound energy?
Most commonly by the use of loudspeakers. The electrical current flowing through a coil (thus making a magnetic field), which attracts an iron slug (a solenoid), which is glued to a piece of heavy paper (the diaphragm of the speaker), When the paper moves it compresses air, which we hear as sound.
Why can't a piece of paper reflect light?
Because the light can shine through it?
Can gases go through any piece of materials?
Yes gases can go through any peice of materials accept from paper. Einstein found it out

What is the difference between a Drawing and a Sheet?
A sheet is just a simple piece of paper you can draw on while a drawing is a picture that someone has drawn and is on paper.
What is example of adhesion?
Adhesion is when a molecule attracts to a different substance. An example of this is when one end of a piece of paper towel is dipped into a glass of water. They water will climb up the fibers of the paper.

Use a protractor or a compass
How do you fit your body in a piece of paper?
you cut the paper up, down,up,down until the end then open the paper up then leave the end 2 rows then cut the inside ONLY. then put it through your body.there you have yourself a piece of paper through your body!:)
