I don't understand how to figure out part b and c based on the equation on page 20

Prof. Tsybychev said...

Think how the mass and length are related to mu

I still can't figure out part B. If you quadruple the mass, doesn't the "quadruple" get cancelled out?

Olivia said...

For part B, you divide by 2 and for part C you multiply by 2. I just don't understand why 100%?

what enters the formula is not the mass but mass per length, this is what mu stands for
