question 1 options:

conduction

friction

induction

reduction

question 2 (1 point)
match the term to the correct description.

question 2 options:

a property of subatomic particles that can exert a force on another object with or without touching

a negative particle, always in motion, surrounding the nucleus of an atom.

a positive particle in the nucleus of an atom.

what two opposite charges do.

what two like charges do.

1.
proton

2.
electron

3.
electric charge

4.
attract

5.
repel

question 3 (1 point)
a charged balloon is brought near an electroscope but does not touch the electroscope. this is an example of charging by

question 3 options:

convection

conduction

induction

friction

question 4 (1 point)
what causes an electric current in a wire?
question 4 options:

electrons move because of heat.

electrons build up in the wire and create a charge.

magnetic fields cause atoms to move in the wire.

electrons flow because of electrical attraction and repulsion.
question 5 (1 point)
if a negatively charged rod touches a conductor, the conductor will be charged by what method?

question 5 options:

induction

friction

convection

conduction

question 6 (1 point)
how do objects become electrically charged?

question 6 options:

protons move from one object to another.

electrons move from one object to another.

neutrons and electrons trade places.

neutrons move from one object to another.

question 7 (1 point)
which of the following would be the best conductor of electricity?

question 7 options:

plastic

glass

aluminum

wood

question 8 (1 point)
how does an insulator stop the flow of an electric current?
question 8 options:

insulators have too many electrons.

insulators have a positive charge, so they absorb electrons.

insulators do not allow electrons to move easily through them.

insulators convert electric energy to other forms of energy.
question 9 (1 point)
which of the following materials is a conductor of electric current?
question 9 options:

a wooden spoon

a glass window

a plastic game piece

a copper penny
question 10 (1 point)
which of the following materials is an insulator against electric current?

question 10 options:

copper penny

a silver necklace

a rubber tire

copper wire

question 11 (1 point)
the electrons in a certain material are closely bound to their atoms and cannot move around very much. this material would be an electric

question 11 options:

conductor

polarizer

diode

insulator

question 12 (1 point)
what happens when a positively charged rod is brought near a neutral plastic ball

question 12 options:

there would be no effect on the charge of the plastic ball as the items must be touching to transfer electric charge.

protons on the ball are attracted to the positive rod and move to the near side of the ball

electrons in the ball are attracted to the near side of the ball

electrons in the ball are repelled to the far side of the plastic ball

question 13 (1 point)
which statement best describes how charges behave?

question 13 options:

opposite charges attract to each other and like charges repel against each other.

charges do not interact with each other.

opposite charges repel against each other and like charges attract to each other.

charges do not exist.

question 14 (1 point)
the negatively charged balloon is brought near the two cans. what happens?

question 14 options:

the negative charges in can b move towards the balloon.

the positive charges in can a move away from the balloon.

the charges in the cans will not change, because charged particles must touch for a charge to transfer.

the negative charges in can a move away from the balloon.
