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. Homework Statement
frequency (f)=160hz
Force (F)=150 Newtons
wavelength (λ)=0.40m
mass(m)=6 grams
find the length of a string with these properties
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.
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.
