An electron is to be accelerated from 3×10^6m/s to 8×10^6m/s. Through what potential difference must the electron passes to accomplish this?Through what potential difference must the electron passes if it is to be slowed from 8×10^6m/s to a halt?

Occurs when an energy source transfers heat directly to another subject space; an example would be an object becoming warm by sitting in the sunshine
