According to the research, the correct option the eardrum. Sound waves that enter the ear canal are directed to the <u>eardrum</u>, causing it to vibrate.
<h3>What is the
eardrum?</h3>
It is the membrane found in the middle ear of vertebrate animals, separating this sector from the external auditory canal.
When sound waves enter through the external auditory canal, the eardrum vibrates, transmitting its movement to the middle ear through a series of bones and in this way, the pressure change is transformed into a mechanical movement.
Therefore, we can conclude that according to the research, the correct option is the eardrum. Sound waves that enter the ear canal are directed to the <u>eardrum</u>, causing it to vibrate.

Answer:
Rubber or plastic covers are bad conductors of electricity. So they do not allow the electric current to pass through it.
Explanation:
Rubber and plastic are bad conductors of electricity, therefore when handling a tool with a rubber handle, the electricity will not pass through it.
the answer is the Spiral Galaxy
Use the formula for mechanical advantage of simple machines. As for a lever, use formula below
mechanical advantage = force output/force input
where
Force input = 330 N
mechanical advantage = 1.6
substitute all the given data, we will get Force output
Force output = 528 N
