Answer:
Explanation:
A )
Th expression for time period for a spring -mass system is as follows
T = 2π
So if mass is doubled , Time period will be √2 or 1.414 times or 5.9 s
B )
If the mass is halved , time period becomes 1 / √2 times or .70 times or 3.0 s
C)
Time period does not depend upon the amplitude of oscillation . So in this case time period will be unchanged ie 4.2 s
D )
As per the formula above , if spring constant k is doubled , time period will be 1 / √2 times or .70 times or 3.0 s
The amount of energy that a wave may transfer to a unit area of a surface each second is measured as the wave's intensity. Watts per square meter is a unit used to express intensity. A sound wave's frequency is equal to its rate of vibration, and its intensity is determined by its amplitude.
<h3>What is the intensity of sound waves affect the frequency?</h3>
The energy of a vibration is quantified in decibels as intensity or loudness (dB). A sound has a high intensity if it is loud.
Therefore, perceive noise as louder the higher the frequency, although frequency does not indicate how loud a sound is.

Hi, thank you for posting your question here at Brainly. I hope I would be able to answer your question.
From the problem statement, it is mentioned that Chip based it from human behavior as a result of the unconscious minds. Hence, the approach Chip used is Psychodynamic/Psychanalysis, which deals with the reasoning of human behavior by studying his past experiences that may have made a significant imprint on his unconscious mind.
Answer:
The beat frequency is 5.5 Hz.
Explanation:
f = 110 Hz, T = 600 N , T' = 540 N
let the frequency is f'.
So, the beat frequency is f - f' = 110 - 104.5 = 5.5 Hz
