In physics, you can apply Hookeâs law, along with the concept of simple harmonic motion, to find the angular frequency of a mass on a spring. And because you can relate angular frequency and the mass on the spring, you can find the displacement, velocity, and acceleration of the mass. Hookeâs law says that F [â¦]
The formula for speed is velocity= wavelength x frequency If the speed of sound in water is 1430m/s you would replace that as the velocity. 1430= wavelength x frequency â¦ Frequency is 286 Hz, therefore you would replace that for the frequency in the equation.
