Question 1144677
--------------------------------------
frequency in hertz (Hz) of a guitar wire varies directly as the square root of the tension and
inversely as the length. If a wire 500 mm long under 25 kg of tension vibrates at 256 Hz
--------------------------------------


{{{y=k*sqrt(25)/500}}}

{{{k*5/500=256}}}

{{{k(1/100)=256}}}

{{{k=25600}}}

-

{{{system(y=25600*sqrt(T)/L,T_tension,L_length)}}}



------------------------------------------
what is
the frequency of a wire 450 mm long under a tension of 30 kg?
------------------------------------------


{{{25600*sqrt(30)/450}}}{{{Hz}}}
