Answer:
(a) 
(b) 
Explanation:
Given data
Area A=4.0 cm²=0.0004 m²
Electric permittivity ε=8.854×10⁻¹² farads/meter
Charge q=0.708 nC
To find
(a) Potential at distance=1.00mm
(b) Potential at distance=2.00mm
Solution
For (a) Potential at distance=1.00mm
First we need to find the capacitance
So

As we know that

So Electric potential is given as:

For (b) Potential at distance=2.00mm
First we need to find the capacitance
So

As we know that

So Electric potential is given as:

They are quantities with magnitude and direction like velocity, we'd be doomed without them to be honest , just knowing how fast something is going isn't enough, you want to know where it is going
This process of physically separating a single phase mixture into several components would be termed simple distillation, I believe.
As it is mentioned that one is separating them based on their different boiling points.

Answer:</h2>
The <u>interstellar medium</u> is the content of matter and energy that exists between stars within a galaxy.
In this sense, two components can be distinguished in the interstellar medium: dust particles and gas.
Dust represents 1% of the interstellar medium in mass, while the gas (consisting mainly of hydrogen and helium) represents 99% of the mass of the interstellar medium.
It should be noted that the interstellar matter is not uniformly distributed but is concentrated in molecular clouds.
