81. To oscillate in four loops means n = 4 in Eq. 16-65 (treating both ends of the string as effectively “fixed”). Thus, λ = 2(0.90 m)/4 = 0.45 m. Therefore, the speed of the wave is v =

Unformatted text preview: f λ = 27 m/s. The mass-per-unit-length is μ = m / L = (0.044 kg)/(0.90 m) = 0.049 kg/m. Thus, using Eq. 16-26, we obtain the tension: τ = v 2 = (27 m/s) 2 (0.049 kg/m) = 36 N....
