Answer:
Current in the circuit(I) = 0.5 ampere
Explanation:
Given:
Number of resistors = 2 (10 ohm each)
Series of resistors
EMF = 10 volt
Find:
Current in the circuit(I)
Computation:
Total resistance in series = R1 + R2
Total resistance in series = 10 + 10
Total resistance in series = 20 ohm
Current in the circuit(I) = EMF / Total resistance in series
Current in the circuit(I) = 10 / 20
Current in the circuit(I) = 0.5 ampere

Take the stone's position at ground level to be the origin, and the downward direction to be negative. Then its position in the air at time is given by
Let be the depth of the well. The stone hits the bottom of the well after 5.00 s, so that
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.

Work done = 0.5*m*[(v2)^2 - (v1)^2]
where m is mass,
v2 and v1 are the velocities.
Given that m = 1.50 x 10^3 kg, v2 = -15 m/s (decelerates), v1 = 25 kg,
Work done = 0.5 * 1.50 x 10^3 * ((-15)^2 - 25^2) = 3 x 10^5 joules
Just ignore the negative value for the final result because work is a scalar quantity.
