Its an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell.
The most common liquid on planet earth is water
The basic principles that apply to circuits is that electrons must receive energy from a source, and electrons transfer energy to perform some useful function.
<h3 /><h3>What is circuit?</h3>
Individual electronic components, like resistors, transistors, are connected by metallic wires or traces by which the electric current can flow to form a circuit design.
The basic principles that apply to circuits will be;
1. Electrons must receive energy from a source.
2. Electrons transfer energy to perform some useful function.
Hence, option 1 and 2 are correct.

Answer:
the final kinetic energy is 0.9eV
Explanation:
To find the kinetic energy of the electron just after the collision with hydrogen atoms you take into account that the energy of the electron in the hydrogen atoms are given by the expression:
you can assume that the shot electron excites the electron of the hydrogen atom to the first excited state, that is
-10.2eV is the energy that the shot electron losses in the excitation of the electron of the hydrogen atom. Hence, the final kinetic energy of the shot electron after it has given -10.2eV of its energy is:
