Answer:
The electric field is 
and the ditection is from outer to inner side of the membrane.
Explanation:
We know the electric field (
) is given by 
, 'V' being the potential.
In 1-D, it can be written as
where 'd' is the separation of space in between the potential difference is created.
Given, 
and the thickness of the cell membrane is 
.
Therefore the created electric field through the cell membrane is
It would be B since it starts with the solar energy which is converted to electricity with the solar panels, which then creates mechanical energy for the fans blades to move and sound for the radio.
Hope that helps :)
This question apparently comes after an EARLIER one,
where you were told either the voltage across the same
capacitor or the total charge stored in it. You can't answer
THIS one without that information.

Answer:
If conditions are just right, you can see Polaris from just south of the equator. Although Polaris is also known as the North Star, it doesn't lie precisely above Earth's North Pole. If it did, Polaris would have a declination of exactly 90 degree.
