Answer:
An atom is the smallest unit of ordinary matter that forms a chemical element.
Matter is composed of very tiny or microscopic particles called "Atom".
(According to Dalton atomic theory some of his principles were wrong and later was corrected but the definition of an atom was right in his theory).

(a) 3000 V
For two parallel conducting plates, the potential difference between the plates is given by:
where
E is the magnitude of the electric field
d is the separation between the plates
Here we have:
is the electric field
d = 4.00 cm = 0.04 m is the distance between the plates
Substituting,
(b) 750 V
The potential difference between the two plates A and B is
Let's take plate A as the plate at 0 volts:
The potential increases linearly going from plate A (0 V) to plate B (3000 V).
So, if the potential difference between A and B, separated by 4 cm, is 3000 V, then the potential difference between A and a point located at 1 cm from A is given by the proportion:
and solving for V(1 cm) we find:
No, simple machine will have an efficiency of 100% if he output work of the machine is equal to the work input.
