1) 
The capacitance of a parallel-plate capacitor is given by:

where
is the vacuum permittivity
A is the area of each plate
d is the distance between the plates
Here, the radius of each plate is

so the area is

While the separation between the plates is

So the capacitance is

And now we can find the energy stored,which is given by:

2) 0.71 J/m^3
The magnitude of the electric field is given by

and the energy density of the electric field is given by

and using
, we find

1. No they aren’t because they all belong to different sports and are used differently
Most objects move at a constant speed because of friction and acceleration. The constant speed keeps them in place, and keeps a balance.
Answer:
Oi, mate its false
Explanation:
because if an leaf floats down from a tree it is not considered an object for a free-fall
I’m pretty sure it is an object with a net force of zero. All forces are balanced and EQUAL
