An elephant produces a 10Hz sound wave. Assuming the speed of sound in air is 344/s, determine the wavelength of this infrasonic sound wave.

34.5 m

Explanation:

Given data : An elephant produces 10 Hz sound wave. Assuming the speed of sound in air is 345 m/s. To find : What is the wavelength of sound ? Answer : The wavelength of the sound is 34.5 m.

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

not too sure thinking all accelerations are pointed down
