In a neutral atom, the number of electrons is equal to the number of _______.

Neutrons

Orbits

Protons

subatomic particles

If two charges repel each other, the two charges must be

negative and negative

An object becomes charged when the atoms in the object gain or lose

electrons

protons

neutrons

all of the above

If you rub a glass rod with a piece of silk, the rod becomes positively charged. This means that

friction destroyed electrons in the rod.

the silk has become negatively charged.

protons have moved to the rod.

glass attracts more protons.

If you bring a charged object near an electrically neutral surface without allowing the object to touch the surface, the charges in the surface are rearranged by

friction.

convection.

induction.

conduction.

Objects that have opposite charges

are attracted to each other, and the force between the objects pulls them together.

are attracted to each other, and the force between the objects pushes them apart.

are repelled by each other, and the force between the objects pulls them together.

are repelled by each other, and the force between the objects pushes them apart.

A region around a charged particle that can exert a force on another charged particle is called an

electric pulse.

electric charge.

electric force.

electric field.

When you pull a cotton sweater off your skin, electrons are transferred from the ___________________ (cotton, skin) to the __________________ (cotton, skin). As a result, your body acquires a ___________ (+ , -) charge and the cotton sweater acquires a ___________ (+ , -) charge.

skin, cotton, +, -

cotton, skin, +, -

skin , cotton, -, +

A neutron

An atom

11.

If an object has the same number of positive and negative charges, its electrical charge is...

positive

negative

neutral or no charge

opposite

12.

Static electricity is

The balance of electrical charge on an object

The imbalance of electrical charge on an object

The discharge of electrical charge

The build up of protons in the nucleus of an atom

13.

If an atom gain's a proton then

it is positively charged

it is negatively charged

it changes into a new element

it explodes due to nuclear fussion

14.

Materials that tightly hold on to their electrons are considered

Good conductors

Good insulators

Good anti-static agents

Useful for storing charge

15.

Which one of these objects is a good insulator

Copper wire

Glass

Aluminum

Gold

16.

Materials that easily lose or accept electrons are considered

Good conductors

Good insulators

Good anti-static agents

Good for storing charge

17.

What is the major difference between static electricity and current electricity?

Current electricity involves a continuous flow of neutrons; 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

18.

Polarization

Friction

Induction

Conduction

19.

Which technology uses static electrical charge to work

Tesla Coil

Turbine

AC/DC Generator

Photocopy Machine
