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.
Answer and Explanation :
The opposition of the flow of alternating current produced by a magnetic field is called inductive reactance it is denoted by , The value of the inductive reactance depends on the value of inductance. The good thing about inductive reactance is that it is not responsible for the power loss as resistance is responsible for the power loss
