Answer:
The frequency of the second harmonic (
) is 11.97 Hz.
Explanation:
Given;
mass of the string, m = 25 g = 0.025kg
tension on the string, T = 43 N
length of the string, L = 12 m
The speed of wave on the string is given as;
where;
μ is mass per unit length = 0.025 / 12 = 0.002083 kg/m
The wavelength of the first harmonic wave is given as;
The frequency of the first harmonic is given as;
The wavelength of the second harmonic wave is given as;
The frequency of the second harmonic is given as;
Therefore, the frequency of the second harmonic () is 11.97 Hz.
The first one,second one and the forth one are correct
To get the solution you must need to draw a force triangle. Attach the head of the 60N north force arrow with the tail of the 60N east force arrow. The subsequent is the arrow connecting he tail and head of the two arrows.
You get a right angled triangle, and the resultant is (60^2 + 60^2) ^0.5 = 84.85 N or 85 N northeast.
The material in which a wave travels is called a medium. Hope this helps!
