Unformatted text preview: speed will the wave travel if the tension of the same string is changed to 18.7 N? (2 points) μ = T v 2 ⇒ T 1 v 2 1 = T 2 v 2 2 v 2 2 = T 2 T 1 v 2 1 (1 pt) v 2 = q ( 18 . 7 5 . 83 )(16 . 2 m/s ) 2 = 29 . 0 m/s (1 pt) Some possibly useful equations: y = A sin( kxωt ) v = λf = λ T k = 2 π λ f = ω 2 π = 1 T v = q T μ m = μL 1...
