Answer 1

Answer:

HII MATE

HERE'S THE ANSWER

Explanation:

1.There are two main properties of a regular vibration - the amplitude and the frequency - which affect the way it sounds. Amplitude is the size of the vibration, and this determines how loud the sound is. The unit of frequency measurement is Hertz (Hz). A frequency of 1 Hz means one wave cycle per second.

2.pic is above.

3.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.

4.Compression. A compression is a region in a longitudinal wave where the particles are closest together. Rarefaction. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.

5.HOW CAN YOU INCREASE THE FREQUENCY OF A STRINGED MUSICAL...

1.By decreasing the thickness of the string as strings with lesser mass vibrate more and hence frequency is increased.

2.By shortening the length produces the same effect.

3.By increasing the speed by which you pluck the string.

4.By increasing the tension of the string

Answer 2

Answer:

1. There are two main properties of regular vibration

1 amplitude and 2.frequency which affect the way it sounds.

amplitude is the size of vibration this determine how loud the sound is .

the unit of frequency measurement is HERTZ.

3.the sound waves enter the external (outer)ear and travel through a narrow passage way called the ear canal, which lead to the eardrum.The eardrum vibrates from the incoming sound waves and sends these vibration to three tiny bones in the middle ear.

I only know the 2 question so I give the 2 answer

I hope it's helpful to you
