Answer:
The direction of the magnetic field around the coil reverses. The force on the cone now pulls it back in. Repeatedly alternating the current direction makes the cone vibrate in and out. The cone vibrations cause pressure variations in the air, which are sound waves.
Explanation:So as it goes back and forth it makes a sound from the vibration.
Parallel Resistor Equation
If the two resistances or impedances in parallel are equal and of the same value, then the total or equivalent resistance, RT is equal to half the value of one resistor. That is equal to R/2 and for three equal resistors in parallel, R/3, etc.
Answer:
Retail sales is very different from any other type of sales. In order for a retailer to be successful, the training strategies for sales teams should differ greatly. Merriam-Webster defines retailing as the business of selling …
