Answer: 1: (A) They allow electrons to move freely between them. 2: (C) they change their positions relative to one another.
Explanation:
The answer is 5. To find the advantage you just divide 20 by 4.
To solve this problem it is necessary to apply the principles of conservation of Energy in order to obtain the final work done.
The electric field in terms of the Force can be expressed as

Where,
F = Force
E= Electric Field
q = Charge
Puesto que el trabajo realizado es equivalente al cambio en la energía cinetica entonces tenemos que
KE = W
KE = F*d
In the First Case,

In Second Case,



The total energy change would be subject to,


Therefore the Kinetic Energy change of the charged object is 27.976J
When do you gotta turn it in?
844J.
Assuming that there were no encumbrances during it's foreswing and it reached it's full potential at apogee.
