The law of conservation of charge states that...

charge cannot be created or destroyed

all atoms have more protons than electrons

only protons can be rubbed off of an atom

An atom of oxygen has 8 protons and 10 electrons, this means the atom is ____________

negatively charged because it has excess electrons

positively charged because it has excess electrons

positively charged because it has a deficiency of electrons

negatively charged because it has a deficiency of electrons

Which statement is true of a positively charged object?

There is a lack of electrons on a positively charged object.

Positively charged objects do not contain any electrons.

Positively charged objects do not contain neutrons or electrons.

The protons and the electrons are both positively charged on such objects.

What is the end result of charging by contact?

Both object have the same charge, so they will repel one another

Both object have the same charge, so they will attract one another

Both object have the opposite charge, so they will attract one another

Both object have the opposite charge, so they will repel one another

Why does the child's hair stick up?

He gained a charge from the slide, and since he's not grounded, his hairs have the same charge so they repel one another

The boy is grounded since he's at the bottom of the slide

He gained a charge from the slide, and since he's not grounded, his hairs have opposite charges so they repel one another

When hair is neutral, some have a positive side and some have negative side, so they will attract to each other, making it stand up

What is the end result of charging by friction?

Both object have the opposite charge, so they will attract one another

Both object have the same charge, so they will attract one another

Both object have the same charge, so they will repel one another

Both object have the opposite charge, so they will repel one another

A balloon is rubbed against a student's hair and then touched to a wall. The balloon sticks to the wall due to

The balloon has a charge, so it attracts the neutral wall

The balloon is charged neutral, so is the wall, so it attracts to the wall

The balloon is charged opposite the wall, so it attracts to the wall

The wall grounds the balloon, so it sticks

If two balloons have the same charge, what will happen if you place them close to each other?

They will push each other away.

What occurs when two charges are moved closer together?

the force between the charges increase

Which is NOT a similarity between gravitational force and electrical force?

They are both repulsive and attractive

They both depend on the distance

The both involve two objects (either charged or with mass)

They both significantly decrease with distance

If the distance between two charged particles is quadrupled (4 times larger), what will happen to the force between them?

It becomes sixteen times smaller

It becomes sixteen times larger

There are only .......... types of electric charge in nature.

Three (positive, negative, neutral)

THREE (negative, positive, medium)

What does it mean for an atom to be neutral?

It isn't attracted to other atoms.
