Most of the information's required are already given in the question. Based on those information's the answer can be easily deduced.

Wavelength of the sound wave = 0.450 meters

Speed of the sound wave = 330 meters per second

We already know

v=fλ

330 = f * 0.450

f = 330/0.450

 = 733.33 hertz

So the frequency of the wave is 733.33 hertz

Wavelength of the sound wave = 0.450 meters
Speed of the sound wave = 330 meters per second
We already know
v=f<span>λ
</span>330 = f * 0.450
f = 330/0.450
  = 733.33 hertz
So the frequency of the wave is 733.33 hertz

As you ride a bicycle on the sidewalk with a speed of
mixer [17]

Answer:

1.2 seconds

Explanation:

distance = ((final speed + initial speed) * time)/2

Here given:

  • distance: 3.8 meter
  • initial speed: 6.4 m/s
  • final speed: 0 m/s

Solving steps:

3.8 = ((0 + 6.4) * time))/2

3.8 = 3.2(time)

time = 3.8/3.2

time = 1.1875 seconds ≈ 1.2 seconds
