Answer:
The speed of the sound wave on the string is 545.78 m/s.
Explanation:
Given;
mass per unit length of the string, μ = 4.7 x 10⁻³ kg/m
tension of the string, T = 1400 N
The speed of the sound wave on the string is given by;

where;
v is the speed of the sound wave on the string
Substitute the given values and solve for speed,v,

Therefore, the speed of the sound wave on the string is 545.78 m/s.
