Ms Pippin rubbed two balloons with a piece of wool. What will happen when the balloons are brought near each other?
The balloons will repel each other.
The balloons will attract each other.
The balloons will become positively (+) charged.
The balloons will pop.
What is the major difference between static electricity and current electricity?
Current electricity involves a continuous flow of elecrons; static electricity is a sudden transfer of protons
Current electricity can be deadly; static electricity is almost always safe
In current electricity, there's a single transfer of electrons; in static electricity, there's a steady flow of electrons
Current electricity involves a flow of electrons; static electricity involves a single transfer of electrons
What happens when you touch a metal doorknob after rubbing your shoes on the carpet?
The doorknob sends a burst of electric current into your body
Millions of electrons go from your finger into the doorknob
The doorknob sends millions of electrons into your finger
Your finger becomes negatively charged
the negatively charged particle in an atom, moves freely, can be released, shared, or “stolen” from an atom
proton
neutron
electron
Lightning occurs because ___.
the negative charges at the bottom of clouds are attracted to the positive charges on the ground.
the positive charges at the bottom of clouds are attracted to the negative charges on the ground.
the positive and negative charges inside clouds are attracted to each other
All of these reasons are correct.
Why does a Van de Graaff generator make your hair stand up if you touch the dome?
The current is trying to flow out of the hair ends.
The electrons gather on the hair ends and repel each other.
The hair is repelled by the dome of the Van de Graaff generator.
The hair is attracted to the surrounding air.
You walk across a shag carpet and become negatively charged. You became negatively charged because...
Protons from your body traveled to the carpet and therefore you became negatively charged
Protons from the carpet traveled to your body and therefore you became negatively charged
Electrons from your body traveled to the carpet and therefore you became negatively charged
Electrons from the carpet traveled to your body and therefore you became negatively charged.
When rubbing against the conductor what gains electrons?
The metal sphere
The belt
The metal comb
The person touching the sphere
Why did the tin plates jump off the Vaan de Graaf when it was turned.
The plates become positive (+) like the sphere and were repulsed by the similar charge.
The plates become positive (+) like the sphere and were repulsed by the opposite charge.
The plates become negative (-) like the sphere and were repulsed by the similar charge.
The plates become negative (-) like the sphere and were repulsed by the opposite charge.
Why did people's hair stand on end when a person was touched the sphere of Van de Graaff
The positively charged (+) hair was repulsed by the positive charged (+) person and each other.
The positively charged (+) hair was repulsed by the negatively charged (-) person and each other.
The negatively charged (-) hair was repulsed by the negatively charged (-) person and each other.
The negatively charged (-) hair was repulsed by the positively charged (+) person and each other.
If something loses electrons it becomes...
Positively charged (+)
Negatively charged (-)
