AI Thread Summary
To find harmonics, multiply the harmonic number by the fundamental frequency. For a fundamental frequency of 343Hz, the first four harmonics are 343Hz, 686Hz, 1029Hz, and 1372Hz. This calculation is straightforward for a string vibrating in a fundamental mode. While complexities can arise in different scenarios, this case is simple and typical. The discussion confirms that there is nothing special about this situation regarding harmonic calculations.

In finding harmonics do you just multiply the harmonic number times the frequency? Find the first four harmonics when f=343Hz would be f1=343Hz, f2=686Hz, f3=1029Hz, and f4=1372Hz. This just seems too easy.

That's basically it! There are situations where it's a bit more complex (oddly shaped waveguides, nonuniform media etc.) but that's not the case here (unless there is other pertinent information you have not disclosed).
 
The problem reads exactly A string vibrates in a fundamental mode at 343Hz. Find the first four harmonics. Is this a special situation??
 
Nope - nothing special about that! For a string the harmonics are simple!
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
