When sound waves cause the eardrum to vibrate, these vibrations are immediately passed on to the _______________.
outer ear and ear canal
tiny hairs
three small bones in the middle ear
inner ear
Answer: three small bones in the middle ear
Explanation: Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.
When sound waves cause the eardrum to vibrate, these vibrations are immediately passed on to the three small bones in the middle ear. So, the correct option is C.
What are Sound waves?A sound wave is defined as a pattern of disturbance that is caused by the movement of energy that travels through a medium such as air, water or any other liquid or solid substance as it propagates away from the source of the sound which is the object made by vibration and pressure generate waves, for example, a ringing cellphone.
These waves enter the outer ear and pass through a narrow passage called the ear canal leading to the eardrum which vibrates with the incoming sound waves and sends these vibrations to three small bones in the middle ear where these bones are called malleus, incus. and steppes.
Thus, the correct option is C.

I do not understand Net Force at all- I would really appreciate it! I'll also include a brainliest since it is quite a bit! Thank you!
Answer:
See below
Explanation:
Net Force is the force which is the sum of all the forces acting on object i.e. pushing of pulling.
Net Force:
1) 4N (net force is 4N to the left)
2) 2 - 7 = -5N (net force is 5N to the left)
3) 4 - 4 = 0 (net force Zero)
4) 6 + 3 = 9N (net force is 9N to the right)
5) 4 - 8 = -4N (net force is 4N to the left)
6) 4 - 5 = -1N (net force is 1N to the left)
7) -3 - 3 = -6N (net force is 6N to the left)
8) 2 + 4 - 5 = 1N (net force is 1N to the right)
9) 3 - 6 = -3N (net force is 3N to the left)
10. 4 + 4 - 7 - 1N (net force is 1N to the right)

How long will it take for an object to hit the ground when dropped from a height of 7m?
Answer:
Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s.

What do you understand by the statement-The heat of vaporization of water is about 2,260 kJ/kg
Answer:The statement "The latent heat of vaporization of water is 226kj/kg." means the amount of heat energy needed to convert one kilogram of water from the liquid phase to vapor is 226kj/kg. Here, the term "latent" refers to a phase-changing process and the term "vaporization" refers to the phase change from liquid to gas

In 3-5 complete sentences, compare the three ways that waves change direction.
Answer:
There are many ways to compare waves and how they change direction. The most common way is through the wind. This is different from human force because of direct contact in the wind and human force. However they both intact something physically moving the ocean. This compares how different waves move.

Answer:
Reflection is the change in direction of a wave between two different objects such that the wave returns to the medium from which it began. In other words, the waves are sent back towards the source. Sound waves, light waves, and water waves can all be reflected.
Explanation:
Incident Ray – the wave/ray traveling towards a surface
Angle of Incidence – the angle at which the traveling wave/ra
y hits a surface
Equal (or Normal) – divides the two rays (incident / reflected) into two equal angles
Angle of Reflection – the angle at which the reflected wave returns towards the original medium
Reflected Ray – the wave/traveling away from the “hit” surface, and now traveling towards the original medium

Do you think his evidence is strong? Why or why not?
Answer:
No
Explanation:
The reason why Barry's evidence isn't strong because "it's not enough to support his claim" that strong magnets repel and weak magnets attract. Barry needs to have at least three trials for each test to greater prove his claim. Doing so will show that the test isn't incorrect because he repeated the test multiple times and got the same results. If Barry does three trials for each test and record his results then he would have enough evidence to support his claim.
Hope this helps.
No, the evidence is not strong enough, as there is a lack of repetition and information on how the experiment was done.
What is missing?
The first thing that is missing is information on how the experiment was done, things like
How strong is the strong magnet?How strong is the weak magnet?Which pole is which on each magnet?Strong and weak magnets behave in the same way, opposite poles attract and equal poles are repelled, thus, there must be a problem with Barry's experiment.
Ignoring that, another problem is the lack of repetitions. An experiment must be done several times to see if the results are always the same, in the given evidence it was done only once for each, so we don't know if after another trial the outcomes will be the same.
