Going through my physics assignment tonight, so that's 10 questions I'll be posting. Since I'm thoroughly hopeless at this subject most of my attempts will be based on my elite google-fu or trawling through lecture notes, bear with me and thanks! 1. The problem statement, all variables and given/known data frequency (f)=160hz Force (F)=150 newtons wavelength (λ)=0.40m mass(m)=6 grams find the length of a string with these properties 2. Relevant equations f(λ)=sqrt [F/(m/L)] found this formula and the statement "solve for L" for this exact question online. I put the values in above, I believe I interpreted them right. 3. The attempt at a solution It seemed a bit dodge to re-arrange, but i got L on it's own to be: L= [F/(fλ ^2)]/m (with values) [150/(160x0.40)^2]/6=0.0061m...I have a feeling I may be off here XD.
