A 35.0-gram, 8.80-meter string is subject to a tension force of 42.0 N, with both ends fixed. Adopt a coordinate system in which the string lies along the x-axis, with one end at x = 0 and the other at x = 8.80 m. (A) Determine the positions (x-values) of the nodes and antinodes when the string is exhibiting the third harmonic. (Enter your answers, in m, from smallest to largest.)
1st node
1st antinode
2nd node
2nd antinode
3rd node
3rd antinode
4th node

(B) At what frequency (in Hz) does this third harmonic vibrate?
