An airplane is heading due south at a speed of 430 km/h . A wind begins blowing from the northwest at a speed of 85.0 km/h (aver
age).What should the plane's course shift be so that it will fly due south?

Explanation:
The equation of the speed of a mechanical wave in terms of the tension and linear density, of the cable in our case, is given by:
Where:
- T is the tension of the cable (T = 572 N)
- μ is the linear density of the cable (μ = 0.109 kg/m)
And we know that v = λ*f
- λ is the wavelength
- f is the frequency
Because a standing waves pattern is produced that has 4.5 wavelengths between the two poles and the distance between poles is 19.9 meters, the value of the wavelength is: λ = 19.9/4.5 = 4.4 m.
Therefore, the frequency will be:
