Why can sounds range from barely audible to deafeningly loud?
1 answer:
Answer:
This is due to the frequency
Explanation:
All sounds are characterized by the frequency range they have, the frequency is the number of times a sound wave is repeated in an instant of time called period.
To better understand this concept, an image is attached in which you can see the different types of waves according to their frequency. We can see that the audible frequencies are within the range of 10^3 to 10^8 [Hz].
Outside this range sounds are imperceptible to the human ear, which is why we cannot hear sounds emitted by physical or similar phenomena. It should be noted that as the frequency of the sound wave increases, the audible capacity of the human ear decreases.

Answer:
The minimum compression is
Explanation:
From the question we are told that
The mass of the block is
The spring constant is
The coefficient of static friction is
For the the block not slip it mean the sum of forces acting on the horizontal axis is equal to the forces acting on the vertical axis
Now the force acting on the vertical axis is the force due to gravity which is mathematically given as
And the force acting on the horizontal axis is force due to the spring which is mathematically represented as
where x is the minimum compression to keep the block from slipping
Now equating this two formulas and making x the subject
substituting values we have
