The correct answer is - federal government system.
Even though all of the countries in the European Union are separate countries and they all have their own governments, still the European Union has authority over them. The European Union has its own parliament, and one of the main conditions for every country member is that it obliges to respect and implement the decisions of this parliament, thus losing little of their sovereignty in the process. This is pretty much the same principle used in the federal government systems, where all states have their own leaders and have big authority in their own borders, but also have to obey the commands and decisions of the central government.
The current flowing through the circuit A is . I = e/r1 + r2.
<h3>What is circuit diagram?</h3>
An electrical circuit is depicted graphically in a circuit diagram. Simple pictures of the circuit's parts are used in pictorial circuit diagrams, where as standardised symbolic representations are used in schematic diagrams to depict the circuit's parts and connections.
"Your question is not complete, it seems to be missing the following information",
find the the current flowing through the resistors in circuit A;
The given parameters;
emf of each battery = e
internal resistance of circuit A = r₁
resistance of circuit = r₂
The equivalent resistance of the circuit A in series is calculated as follows;
Re = r1 + r2
emf = e
The current flowing through the circuit A is calculated as follows;
V = IR
I =V/R
I = e/r1 + r2
Thus, the current flowing through the circuit A is . I = e/r1 + r2

Answer: Electron flow / Electric current
Answer:
(507 nm)
Explanation:
First of all let's calculate the energy of the photon absorbed by the electron, This is given by
where
h is the Planck constant
is the frequency of the photon
Substituting,
The energy of the second photon, the one emitted when the electron drops to the intermediate energy level, is 2/3 of this energy:
The relationship between the energy of the photon and its wavelength is
where c is the speed of light. Solving for , we find the wavelength:
