We know, Wavelength = speed / frequency

Highest frequency (normally that humans can hear) = 20 KHz
= 20,000 Hz  (for shortest wavelength)

Speed = 343 m/s

Substitute their values, 
wavelength = 343 / 20,000
w = 0.01715

In short, Your Answer would be: 0.01715 m

Hope this helps!

F = 1/T = 20,000 so T = 1/20,000 
<span>distance = speed * time </span>
<span>L = 343 T </span>
<span>L = 343/20,000 </span>
<span>L =. 01715 meters or about 1.7 centimeters</span>

Answer:

M = ρ V = 9 gm/cm^ 3 * cm^3 = 27 gm

a = (V2 - V1) / t = (6 - 2) m/s / 12 s = 1/3 m/s^2     the acceleration

F = M a = 27 gm * 1/3 m/s^2 = 9 dynes      net force applied
