Explain the transformation that takes place when you turn on a flashlight. From the battery to the light. 4 steps

What is Chemical (of the battery) to electrical (flow of electrons) to radiant (of the light) to thermal ( the heat produced by the light)

200

Is this material magnetized?  Why or why not?

No it is not magnetized.  In a magentized material, al or most of the magnetic domains are arranged in the same direction.

200

Electric charges can build up through friction between two materials that differ in their ability to give up or accept electrons.  What is this called?

Static electricity

If an item is dropped from a mile above the Earth, why does it reach a certain velocity and not continue accelerating?   What is the name of the velocity that an object attains in free fall?

There is air resistance (a force going up) which is opposing the motion down.   The final velocity is called terminal velocity.
