What kind of rod can be charged by rubbing it with a duster?
Traditionally an amber rod, but a toothbrush handle or a comb will also work.
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.
Is a plastic comb a conductor or insulator?
Plastic is generally an insulator, so a plastic comb cannot carry energy.
When you comb your hair with a plastic comb what will the sign be on the charge acquired by the comb?
Negative.
What happen when rubbing a comb and place near to a flowing water?
explain why?

Why does a plastic comb rubbed with a duster cause a thin stream of water to bend?
When you rub the comb against the duster it charges up the electrons,the electrons in the comb and the electrons in the water will repel
What brushes can you clean your horse feather duster tooth brush curry comb hard brush?
Curry comb or hard brush.
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.

Why does a comb attract pieces of paper even when it is not charged?
Nope, this does not contradict coulomb's law. 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.

Negative.
If you scuff electrons from your hair onto a comb are you positvely or negatively charged and how about the comb?
Your creation of friction with the floor will allow you to "collect" electrons. You'll become negatively charged, and this static charge can discharge to a door knob. Most of us are familiar with the phenomenon. The results can be shocking.
What is a plastic comb made from?
Plastic and recalled things
What happen when rubbing a comb and place near to a flowing water?
explain why?
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.
