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 ;)

Which converts mechanical energy to electrical energy

a generator

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

negative

How much current will a 120-V wall outlet push through a 20-ohm circuit

6

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

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.

In terms of the scientific definition of work magnetic fields can do work but electric fields cannot true or false

false
