Why does increasing temperature increases vibration of molecules in conductors so it decreases it’s conductivity while in semi-conductors it increases it’s conductivity and no vibrations occurs in the molecules! ?

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

co2reflects heat radiation back to earth buning coal and oil emits co2 globe warms

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

the answer should be in the picture.
