electrostatic charge pre test

Two objects have collected static electricity with the same charge. How would the two objects behave when placed near each other?

• attract

• nothing

• repel

• stick together

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

In the diagram, the objects are apart. What does that indicate about the charges on the two objects?

• Both objects are negative.

• Both objects are positive.

• One object is positive, the other is negative.

• The objects have the same charge.

Why would a comb which is running through hair touches one object and causes the two objects to come together?

• Because of the different charges that the objects already had.

• Because of the negative charge. already had.

• Because of the positive charge.

• Because of the same charge that the objects

• lightning energy

• static electricity

• turbine electricity

What will happen if you add more batteries to an electrical circuit containing light bulbs?

• The bulbs will be brighter.

• the bulbs will dim.

• The bulbs will last longer.

• There is no change.

Which material acts as a conductor of electricity?

• paper clip

• plastic button

• popsicle stick

• rubber glove
