A trumpet creates a sound wave that has a wave speed of 360 m/s and a wavelength of 0.8 m. What is the frequency of the sound wave? A. 450.0 Hz, because frequency is equal to wave speed divided by wavelength

B. 280.0 Hz, because frequency is equal to wave speed multiplied by wavelength.

C. 0.002 Hz, because frequency is equal to wavelength subtracted from wave speed.

D. 70.0 Hz, because frequency is equal to wavelength multiplied by wave speed.

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?
