[b]Hi everyone ^^ :D
I am very weak at physics, so I hope that someone may help me with these questions
1. The frequency [i]f[/i] of the note produce by a streched string depends on its length [i]l[/i] the tension [i]T[/i] of the string and the mass per unit lenght [i]m[/i] of the string. Use the method of dimension to derive an equation for [i]f[/i].
