Answer:
T = 69.49 N
Explanation:
The relation between the tension and speed of a wave is:
(1)
Where:
- T is the tension of the string
- μ is the linear density (8.20*10⁻⁴ kg/m)
- v is the speed of the wave
Let's recall, that the speed of a wave is the wavelength times the frequency, so:
Now, we just need to solve the equation (1) for T and use the value of v we found before.
Therefore the tension of string is 69.49 N.
I hope it helps you!
Answer:
if there is any phase between the waves this value is less
if the sine function is ±, the amplitude of the total wave is
A_total = A₁ + A₂ + A₃+ A₄ +A₅
Explanation:
When several waves travel in the same direction, the process of adding them can take place.
y_total = ∑
where
y_{i} = A_{i} sin (k x - w t + Ф)
with fi the phase of each wave
To produce the largest possible result, all waves must come with the same phase
y_total = (A₁ + A₂ + A₃ + A₄ + A₅) sin (k x - wt)
if there is any phase between the waves this value is less
if the sine function is ±, the amplitude of the total wave is
A_total = A₁ + A₂ + A₃+ A₄ +A₅
