Answer:
a
The total charge is 
b
The change in potential energy is 
c
The height is 
Explanation:
From the question we are told that the
The magnitude of electric field is 
The number of proton is 
The distance between the plates is 
The total charge can be mathematically represented as
Where e is the charge on one proton which has a value of 
Substituting values
The change in potential energy is mathematically represented ads
where the negative sign shows that the work done by the electric force is against the electric field
Substituting values
The mass of the bead is given as 0.05kg
The change in potential due to gravity is mathematically given as
the negative sign is due to the fact that the height is decreasing
And 
Making h the subject
Substituting values
At the top of the mountain, when he tightens the cap onto the bottole, there is some water and some air inside the bottle. Then he brings the bottle down to the base of the mountain.
The pressure on the outside of the bottle is greater than it was when he put the cap on. If anything could get out of the bottlde, it would. But it can't . . . the cap is on too tight. So all the water and all the air has to stay inside, and anything that can get squished into a smaller space has to get squished into a smaller space.
The water is pretty much unsquishable.
Biut the air in there can be <em>COMPRESSED</em>. The air gets squished into a smaller space, and the bottle wrinkles in slightly.
Below are the choices that can be found from other source:
a. 0.3 AU
<span>b. 3.8 AU </span>
<span>c. 30 AU </span>
<span>d. 3 million AU
</span>
Answer is c. 30 AU.

==> Infrared waves from the sun, green light from the sun, and X-rays from the sun, all travel through vacuum.
==> Ocean surf waves travel through water.
==> Microwaves in an oven travel first through air, and then later through meatloaf or chicken.
==> Seismic waves (earthquakes) travel through rocks and dirt.
U = 1/2 * k * x²
U = 0.003J
x = 0.0055m
