please help the assignment is due in 30mins :(

anonymous · Answer

ok, what expression are you using for frequency as a function of tension?

anonymous · Answer

f=sqrt T?

anonymous · Answer

pretty much, all else being constant and for the purpose of the problem

so:

anonymous · Answer

$$\frac{ f _{1} }{f _{2}} = \frac{ \sqrt{.9808T}  }{ \sqrt{T}}$$

anonymous · Answer

Is that all that youre given?

anonymous · Answer

$${ f _{1} } = \sqrt{.9808}  {f _{2}}$$

anonymous · Answer

my f2 is 277?

anonymous · Answer

yep

anonymous · Answer

so find the freq. of the loosened string.

anonymous · Answer

the beat frequency is the difference between the two.
