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?

Employer informs its employees that it will hold a substantial cash prize drawing for each work group at the end of each month in which no employee in the work group sustains a lost-time injury. tyra reports an injury that she sustained while operating a mechanical power press. tyra did not violate any employer safety rules when she sustained her injury. tyra’s injury requires her to miss work for two days. her employer cancels the cash prize drawing for that month for tyra’s work group because of tyra’s lost-time injury. did the employer misuse an incentive program to retaliate against tyra?
