A vertical, 1.26-m length of 18-gauge (diameter of 1.024 mm) copper wire has a 140.0-N ball hanging from it. A 700.0-N ball now replaces the original ball. What is the change in the wavelength of the third harmonic caused by replacing the light ball with the heavy one? (Y=11*10^10 for copper)
Alright
Dude, If that worked for you... dont forget to give THUMBS UP.(that
will work for me!)

If I missed something feel free to leave a comment.
atleast before giving downvote.
and, Thanks for using Chegg- Smarter way to study.
