The solar system is really big! To give you an idea of its dimensions, think that if the Sun was Washington DC and Mercury was t
he size of New York, NY (which is 225 miles from Washington DC), Earth would be approximately in Chicago, IL
This was calculated as a proportion using the data in the table and finding a city corresponding to the proportional distance.
Example:
Chicago, IL (as well as many other locations) is about 581 miles from Washington DC in a straight line. Using the same reasoning as above, in what locations would you expect to find Venus and Jupiter?

C.
Explanation:
The capacitance of a capacitor is its ability to store charges. For parallel-plate capacitors, this ability depends the material between the plates, the common plate area and the plate separation. The relationship is
is the capacitance,
is the common plate area,
is the plate separation and
is the permittivity of the material between the plates.
For air or free space, is
called the permittivity of free space. In general,
where
is the relative permittivity or dielectric constant of the material between the plates. It is a factor that determines the strength of the material compared to air. In fact, for air or vacuum,
.
The energy stored in a capacitor is the average of the product of its charge and voltage.
Its charge, , is related to its capacitance by
(this is the electrical definition of capacitance, a ratio of the charge to its voltage; the previous formula is the geometric definition). Substituting this in the formula for
,
A. Substituting for in
,
B. When the distance is ,
C. When the distance is restored but with a dielectric material of dielectric constant, , inserted, we have
