what did you write for the 6markers

On the potato 6 amek o wrote that conduction cus its stuck in a metal spike and metal is a conductir of heat and convection cus hot air rises and the potatoes are near the top of the oven and radiation because of the ir heat of the heating element and cus is matt blak and matte anbsorbs and radiates most heat wbu..?

I wrote that it uses ac cus ac changes direction constantly and when the coil gets ac current its attractee to the magnets, so it moved back and forth from side to side so it vreats virbartion and thus sound.

And which direction did you say it will move. i said towards the left, due to the movement created, and if the current was reversed it will go the other way
