The correct answer is k = 1.5 *10^12.
The potential difference between two half cells in an electrochemical cell is measured by the cell potential, or Ecell. The capacity of electrons to go from one half cell to the other is what determines the potential difference. The Nernst equation is used to determine the concentration of one of the cell's components or to compute the voltage of an electrochemical cell. Ecell = E0cell - (RTnF)InQ is the Nernst formula. Cell potential is ecell. A galvanic cell or voltaic cell is an electrochemical device that transforms the chemical energy of spontaneous redox reactions into electrical energy. electrical cell A voltaic cell is an electrochemical device that produces electricity through chemical processes.

Answer:
The total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
Answer:
E = 73.5 J
Explanation:
Given that,
Mass of a marble, m = 5 kg
It is placed at the edge of a 1.5 m table
We need of find the gravitational potential energy of the marble. It is given by the formula as follows :
E = mgh
E = 5 kg × 9.8 m/s² × 1.5 m
E = 73.5 J
So, the potential energy of the marble is 73.5 J.
