A hard-rubber or plastic comb rubbed against wool can often be shown to have a static charge. Why does a metal comb not readily show a static charge when rubbed against wool?
I've never heard of a class called "Help please." Please follow directions and put your REAL school subject in the School Subject box.
Well I have been doing that the past 2 days and I haven't been getting help.
That's probably because there have been no tutors online with this particular specialty.
No some will answer other people "physic" questions but not mine. So I thought this time I'll type "please help" to catch someones attention and I did with you.
you caught his attention because you didn't follow instructions, not because it was someone to help. No wonder you are asking others to do homework for you
Poor Ciara... their just rule followers...
When a hard-rubber or plastic comb is rubbed against wool, electrons are transferred from the wool to the comb. This transfer of electrons creates a negative charge on the comb, while leaving the wool positively charged. This separation of charges is what we call static electricity.
Now, let's discuss why a metal comb does not readily show a static charge when rubbed against wool. Unlike hard-rubber or plastic, metals are good conductors of electricity. When a metal comb comes into contact with the wool, any charge that builds up on the comb will quickly flow through the metal and dissipate. This means that the electrons that would have been transferred during rubbing are distributed evenly throughout the metal, minimizing the buildup of a static charge.
Therefore, a metal comb does not readily show a static charge when rubbed against wool because the charges are quickly conducted away through the metal, preventing a significant accumulation of charge.
