When charging an object by conduction what happens to the charges in the object

Electrons move onto the object, giving it a static charge.

Apex ;)

When a fuse blows

When a fuse blows, you should replace the fuse and check to see what might have caused it to blow. It's a sign that there might be something causing too much current to flow in the circuit.

Which converts mechanical energy to electrical energy

a generator

How is the wiring done in houses and other occupied buildings

It is in parallel, so one light can be on while others are turned off.

Electric field lines point in the opposite direction charges would move if they were in the field

negative

When electric and magnetic fields both exist it is called an

electromagnetic

According to Coulombs Law how does distance affect the electric force

electric force can act at a distance bbut is stronger when object are closer

In a series circuit the is the same at every point

In a series circuit the current is the same at every point. This is Kirchoff's current law.

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground

No. Touching a live electric current is never a good idea.

A 120 V power supply connected to a 30 ohm resistor will produce how many amps of current

A 120V power supply connected to a 30 Ohm resistor will produce 120/30 or 4 amps of current.

Which data-storage device will not have its data scrambled by a magnet

CD

What will be attracted to or repelled by an magnet

a copper wire carrying current and another magnet.
