how did all of these scientists experiments give us more knowledge about static electricity?
select an answer
all of the experiments illustrated electricity in the form of magic tricks and other performances.
all of the experiments showed that there was some sort of attraction present.
each experiment explained the concept of positive and negative electric charges interacting with one another to produce static electricity.
each experiment demonstrated electricity that could power objects on or off.

Explanation:

• Option A is incorrect as scientific experiments on static electricity are not about magic tricks.
• Option B is too vague; static electricity involves more than just attraction (repulsion too in some cases, and the key is charge interaction).
• Option C is correct. Static electricity is produced by the interaction of positive and negative charges (like charging by friction, induction, etc.), and experiments on static electricity explain how these charges interact to create static electricity.
• Option D is incorrect as static electricity is not used to power objects on or off in the context of these basic experiments (that's more about current electricity in circuits).

Answer:

C. Each experiment explained the concept of positive and negative electric charges interacting with one another to produce static electricity.
