You repeat the Vibrating Strings experiment $($this time on Earth where $g=9\mathrm{.}80\frac{m}{s^2})$ with a different string than the ones used in lab. A mass of $M=69\mathrm{.}0$ grams suspended from the end of the string produces a standing wave pattern with two antinodes. The distance between the nodes is $30\mathrm{.}0$ cm $.$ The slope of your $\frac{L^2}{M}$ versus $\frac{n^2}{}$ graph is $0\mathrm{.}0150$ cm $.$ What is the mass per unit length $$ of the.string...in grams $\frac{?}{cm}?$

$\frac{g}{c}m$
