As the voltage across the capacitor changes what happens to the capacitor?
There is a direct relationship between the voltage and the charge stored on the capacitor.
The electric potential energy stored in the capacitor changes by the square of the change in voltage.
Both A and B
Neither A nor B
A person combs her hair static electricity is sometimes generated by what process?
Contact when between the comb and hair results in a charge
Friction between the comb and hair transfers electrons
Deduction between the comb and hair
Induction between the comb and hair
Which statement explains why will make the balloon stick to a wall?
Rubbing the balloon on your hair creates a temporary magnet.
The balloon gets static charge when rubbed on someone’s hair.
There is glue on the wall
It is a magic trick.
How can you tell when static electricity has been discharged?
Heat is released that can be felt.
Light is released and you can feel a shock.
Static electricity gives off many different colors.
The object begins to spin rapidly when it is shocked.
Why would a comb that had been run through hair touch one cheerio and cause the two Cheerios to come together. The comb had...
a negative charge
a positive charge
a different charge than the Cheerios already had
the same charge as the Cheerios already had
Two objects have collected static electricity with the same charge. What would the objects do when placed near each other?
repel
attract
nothing
stick together
What will happen if you add more batteries to an electrical circuit containing light bulbs?
There is no change
The bulbs will dim
The bulbs will be brighter
The bulbs will last longer.
How can electric charge be established?
Electrons can be removed from atoms and accumulated to produce a negative charge
Atoms from which electrons have been removed produce positive electric charge
Why does static electricity move from you to a metal object after you have walked over new carpet?
It is attracted to the metal
It is attracted to you
It is attracted to the carpet
It is made in your shoes.
Which form of electric discharge appears in nature?
rain
ocean currents
lightning
volcanoes
