Problem

Which expression gives the speed

v

of a small transverse pulse on a stretched string in terms of the string tension

F_{T}

and the string’s linear mass density

\mu

? a)

v = 2\sqrt{\dfrac{F_T}{\mu}}

v = \sqrt{\dfrac{2F_T}{\mu}}

v = \sqrt{\dfrac{F_T}{\mu}}

v = \dfrac{1}{2}\sqrt{\dfrac{F_T}{\mu}}
