Question

  

                   

                            
           The tension in the wire would decrease.                             
           The tension in the wire would increase.                             
           The wire would need to vibrate at a frequency lower than 53 Hz in order to produce the 2nd harmonic standing wave pattern.                             
           The speed at which waves can move along the wire would decrease.                             
           The speed at which waves can move along the wire would increase.                             
           The wire would need to vibrate at a frequency higher than 53 Hz in order to produce the 2nd harmonic standing wave pattern.

Explanation / Answer

As Tension = mg

So

The tension in the wire would increase.

Velecity = (1/2pi)*sqrt(T/u)

So

As T increases velocity increases

The speed at which waves can move along the wire would increase.

Velocity = Lambda*frequncy

As Velocity increases

Frequency increases

The wire would need to vibrate at a frequency higher than 53 Hz in order to produce the 2nd harmonic standing wave pattern.
