Physics is a branch of science that deals with the properties of matter and energy and relationship between them it also tries to explain the material world of the natural phenomenon of the universe the scope of physics is very wide and vast
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: B,E,F
Explanation:
(B) the inner core is solid. (E) the outer core is liquid and moving. (F) Earth's core is composed of iron and nickel
Answer:
The time period of the object is 0.2 seconds.
Explanation:
An object is oscillating as depicted in the expression below :
........(1)
The general equation is given by :
.......(2)
Comparing equation (1) and (2) we get :
The relation between angular frequency and time period is given by :
T = 0.2 seconds
So, the time period of the object is 0.2 seconds.
What's happening here is that you're changing the potential energy of this object by lifting it 500cm.
Therefore the energy required to lift it would be the additional potential energy it gains. Look at the equation for potential energy:
PE = m*g*h
and convert and plug in your values:
PE = (2.5kg) * (9.8 m/s²) * (0.5m)
PE = 12.25J
