Answer: Taking into account sound is a wave, we can use the information of the displacement (generally given as a graph) to find the wavelength and frequency, then we can calculate the speed with the formula of the speed of a wave.
Explanation:
If we have the displacement graph of the sound wave, we can find its amplitude, its wavelength and period (which is the inverse of frequency).
Now, if we additionally have the frequency as data, we can use the equation of the speed of a wave:

Where:
is the speed of the sound wave
is the wavelength
is the frequency
Answer:
Potential energy turn to kinetic energy
Explanation:
Magnetic fields surround magnets. They attract or repel, depending on the charge of the object in it.
The answer is a. True. Covalent compounds do not conduct electric or does not have electrical properties when dissolved in water as the free moving electrons shared from its original structure is removed when it was dissolved.
