Answer:
The number of people attending the events people
Explanation:
Generally total sound intensity is given as
Where
is the total sound intensity
is the signal level from each single source
n is the number of source
Substituting the given value
97 = 43.2 + 10log(n)
53.8 = 10log(n)
log(n) = 5.38
Raising both sides to the power of 10
Note [ ]
=>
The average rate at which energy is transmitted along the string is 15.1 J/s.
<h3>
What is average power of a wave?</h3>
The average power of a sinusoidal wave is proportional to the square of the amplitude of the wave and the square of the angular frequency of the wave
P = ¹/₂μω²A²v
where;
- ω is angular frequency = 10π rad/s
- A is amplitude of the wave, = 0.35
- μ is linear mass density = 75 g/m = 0.075 kg/m
- k is angular wave number, k = 3π /m
- v is speed of the wave = ?
v = ω/k
v = (10π) / (3π)
v = 3.33 m/s
P = ¹/₂μω²A²v
P = ¹/₂(0.075)(10π)²(0.35)²(3.33)
P = 15.1 J/s
Thus, the average rate at which energy is transmitted along the string is 15.1 J/s.

To solve this problem we will apply the concepts of strain, flow stress and average flow stress to find the required data. We will start by calculating the Strain which is the logarithmic relationship between the longitudinal change. Later we will find the flow stress through the strength coefficient, the strain and the strain-hardening exponent. Finally with the found values it will be possible to find the average flow stress,
Now the strain is calculated with the logaritmic relation of the lengths.
With this value we can calculate the flow stress,
Here,
K = Strneght coefficient
n = Strainhardening exponent of brass
Finally the average flow stress will be given under the relation:
