The separation between the plate is 
The potential difference is 
The permitivity of free space is 
The dielectric constant of glass is K = 5.0
Generally the capacitance of this capacitor is

substituting values


The charge stored is mathematically evaluated as

substituting values


The energy stored is

substituting values


Answer: 7.436 s
Explanation:
This situation is related to vertical motion, specifically free fall and can be modelled by the following equation:
Where:
is the final height of the object (when it makes splash)
is the initial height of the object
is the initial velocity of the object (it was dropped)
is the acceleration due gravity (directed downwards)
is the time since the objecct is dropped until it makes splash

Finally:
Answer:
0.8
Explanation:
The two spheres have the same potential, V.
Let the radius of the larger sphere be R and the radius of the smaller sphere be r,
=> R = 4r
Let the charge on the smaller sphere be q. Hence, the larger sphere will have charge Q - q.
The potential of the smaller sphere will be:

The potential of the larger sphere will be:

Inputting R = 4r,

Since
,

=> Q - q = 4q
=> 5q = Q
q = 0.2Q
The fraction of the charge Q that rests on the smaller sphere is 0.2
The charge of the larger sphere is:
Q - q = Q - 0.2Q = 0.8Q
∴ The fraction of the total charge Q that rests on the larger sphere is 0.8
Answer:
V=3 m/s
t=12 seconds
S=?
S=V×t
S=3×12
S=36meters
So distance you travel is 36meters.
