Why do electrons flow through a wire? a. there is a difference in the chemical energy. b.there is a difference in the potential energy. c.there is a difference in the gravitational force. d.there is a difference in the kinetic energy.

Electrons flow through a wire because THERE IS A DIFFERENCE IN THE POTENTIAL ENERGY. The correct option is B.

The potential difference that exist between the electrons in an electric wire is the major reason why electrons flow through electric wires. The potential difference can be negative or positive depending on the movement of the charges. The amount of work that is needed to move a charge between two point in an electric circuit is called electric potential difference and it is measured in Volts.

explanation:

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
