Because the speed of sound in air is approximately constant (does not depend on frequency or wavelength), we can calculate the speed of sound as long as we know the frequency and wavelength of just one sound wave. The frequency of the highest note on the piano is 4186 Hz and its wavelength is 0.082 meters. Using the equation velocity = frequency*wavelength (written below in math notation), calculate the speed of sound.

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?
