Given: Length (l) = 7 m, Mass (M) = 0.035 kg and tension (T) = 60.5 N. Therefore, mass of string per unit length (m) = 0.035 / 7 = 0.005 kg/m. Speed of wave, v = √(T/m) = √(60.5 / 0.005) = 110 m/s.

1. Mass of string per unit length (m) = 0.005 kg/m
2. Speed of wave, v = √(T/m)
3. v = √(60.5 / 0.005) = 110 m/s
4. Given: Length (l) = 7 m, Mass (M) = 0.035 kg

Correct answer: v = √(60.5 / 0.005) = 110 m/s

Solution

Option C is correct because the calculation of the wave speed using the formula v = √(T/m) and substituting the given values is accurate, resulting in 110 m/s.
