A wire of density 0 is tapered so that its cross-sectional area varies with x according to
A = (1.0 X 10─3 x + 0.010) cm2
(a) If the wire is subject to a tension T, derive a relationship for the speed of a wave as a function of position.
(b) What If? If the wire is aluminum and is subject to a tension of 24.0 N, determine the speed at the origin and at x = 10.0 m.
