Turn off lights when leaving rooms.
Unplug unused appliances. Even when powered off these appliances use electricity.
Replace regular light bulbs with energy saving bulbs.
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
Answer:
I think it has to do something with their ionizations... not entirely sure though.
Explanation:
5
if zero falls between two significant numbers it becomes significant.
