A steel wire has a length of 12 m and a mass of 2.10 kg. What will be the speed of a transverse wave on this wire when the tension of 2.06×104 N is applied?

Hint: Use the formula of the speed of the wave in a string.
Given the length of the wire,             l = 12m 
Mass of wire                                    m=2.10kg
Tension                                           T=2.06×104 N
Step 1: Find the speed of the wave.
Speed of  transverse wave,                      
                                                        v=Tμ                                      [where μ=mass per unit length]
  =2.06×1042.1012=2.06×12×1042.10=343 m/s
