Answer:
Part a)
Part B)
percentage increase is
%
Explanation:
Part a)
As we know that the beat frequency is
after increasing the tension the beat frequency is decreased and hence the tension in string B will increase
So we have
Part B)
percentage increase in the tension of the string will be given as
now we have
so we have
so we have
percentage increase is
If the amplitude is doubled than the intensity will become 4 times of amplitude.
<h3>What is meant by intensity? </h3>
Intensity is the quality of being very strong, concentrated or difficult or the degree to which something is difficult or strong.
The intensity of a sound wave exists described as the amount of energy transmitted through a unit area per unit time in the direction of travel; it is a vector quantity with both a magnitude and a direction.
The amplitude of the sound waves and how far they have travelled from the sound source.
Intensity is directly proportional to the square of the amplitude .
So, if the amplitude is doubled than the intensity will become 4 times of amplitude.

... For most of every night, I exert a significant vertical force on my bed.
But my bed does not move.
... The same is true for the seat of my chair during dinner, and the ground under my feet when I stand or walk.

exerting a considerable horizontal force against it. I have been doing this
for several years now, yet the light pole is still exactly where it has always stood.
