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

What is the net force on this object A: 0 newtons b: 200 newtons c:400 newtons D:600 newtons
Ilya [14]

Answer:

100kg

Explanation:

Total force =400N+600N=1000N

As we have,

F=m×g

1000N=m×10m/s²

1000N÷10m/s²=m

m=100kg
