Answer:
f=171.43Hz
Explanation:
Wave frequency is the number of waves that pass a fixed point in a given amount of time.
The frequency formula is: f=v÷λ, where <em>v</em> is the velocity and <em>λ</em> is the wavelength.
Then replacing with the data of the problem,
f=
f=171.43
f=171.43 Hz (because , 1 hertz equals 1 wave passing a fixed point in 1 second).
Pressure = Force/ Area = 3000/2 = 1500 pascal.
If I remember correctly, it is the 3rd answer choice.
Well you need to have lots of heat
