Answer:
Explanation:
Given that,
The speed of the car is
Vc = 97m/s
The radius of circular path of the car is
Rc = 420m
We want to find the angle of roadway banked β?
To determine the angle of roadway banked, we will use the formula
tanβ = Vc² / Rc•g
Where Vc = 97m/s, Rc = 420m and
g = 9.8m/s²
Then
tanβ = 97² / (420 × 9.8)
tanβ = 2.28596
β = ArcTan ( 2.28596)
β = 66.37°
The railway banked at an angle of 66.37°

<span>So we wan't to know which harmonic is the frequency of Fn=1056 Hz if we know that the fundamental frequency F1=528 Hz. So the frequency of n-th harmonic Fn is fundamental frequency F1 multiplied by n or Fn=n*F1. In our example we know the fundamental frequency and an overtone frequency and we want to know which harmonic it is so we are looking for n. So n=Fn/F1 and after we input our numbers we get that n=1056/528=2. So the frequency of 1056 is the frequency of the second harmonic.</span>
