This device is a transformer.
A transformer is made of two coils. An alternating current in the first coil produces a varying magnetic field and so a varying magnetic flux through the second coil. The varying magnetic flux creates an electromotive force in the second coil, for the Faraday's law of induction, that is proportional to the variation of the flux, and this electromotive force corresponds to the new voltage on the second coil.
The relationship between the voltage in the first coil (Vp) and the voltage in the second coil (Vs) is given by
where Np and Ns are the number of turns in the primary and secondary coil, respectively.
Answer:
Because molecules are to small for us people to see with the bare eye, unless you use a telescope.
Explanation:
That depends on what the sound is traveling through, and the density
and temperature of the substance.
In dry air, at sea-level pressure and 68° F, the speed of sound is
about 340 meters per second (761 miles per hour).
