    Answer: speed of vibration = 146.33m/s

    Explanation: The speed of sound (v) in a string is related to tension (T) and mass per unit length (u) via the formula

    v = √T/u

    T = 621N, m = 32.4g = 0.0324kg, l = 1.12m

    u = mass / length, thus

    u = 0.0324 / 1.12 = 0.029kg/m

    Hence

    v = √621 / 0.028

    v = √ 21,413.793

    v = 146.33m/s
