A parallel circuit exists when an electric charge flows in more than one path best describes it.
<h3>What is a Parallel circuit?</h3>
This type of circuit has branches in which the current divides and only part of it flows through any of the branch.
Parallel circuit having more than one branch therefore means that electric charge will flow in more than one path thereby making option A the most appropriate choice.

Answer:
GAS, LIQUID, CLOUDS
Explanation:
Water can be in three states: solid, liquid and gas, passing from one to another depending on the pressure and temperature.
In this complementation exercise.
When the water cools down the GAS goes to the LIQUID state, these small drops unite and form the CLOUDS
Answer:
0.5 eV
Explanation:
= Initial potential energy = ![2\ eV](https://tex.z-dn.net/?f=2%5C%20eV)
= Final potential energy
= Initial width
= Final width = ![2L_1](https://tex.z-dn.net/?f=2L_1)
Energy of an electron in a one-dimensional trap is given by
![E=\dfrac{n^2h^2}{8mL^2}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7Bn%5E2h%5E2%7D%7B8mL%5E2%7D)
From the equation we get
![E\propto \dfrac{1}{L^2}](https://tex.z-dn.net/?f=E%5Cpropto%20%5Cdfrac%7B1%7D%7BL%5E2%7D)
So,
![\dfrac{E_1}{E_2}=\dfrac{L_2^2}{L_1^2}\\\Rightarrow E_2=\dfrac{E_1L_1^2}{L_2^2}\\\Rightarrow E_2=\dfrac{2L_1^2}{4L_1^2}\\\Rightarrow E_2=0.5\ eV](https://tex.z-dn.net/?f=%5Cdfrac%7BE_1%7D%7BE_2%7D%3D%5Cdfrac%7BL_2%5E2%7D%7BL_1%5E2%7D%5C%5C%5CRightarrow%20E_2%3D%5Cdfrac%7BE_1L_1%5E2%7D%7BL_2%5E2%7D%5C%5C%5CRightarrow%20E_2%3D%5Cdfrac%7B2L_1%5E2%7D%7B4L_1%5E2%7D%5C%5C%5CRightarrow%20E_2%3D0.5%5C%20eV)
The ground state energy will be 0.5 eV
