Answer

To find the energy transferred (E), we can use the equation provided:

  1. Identify the values:

    • Charge (Q) = 0.042 C
    • Voltage (V) = 1.5 V

  2. Substitute the values into the equation:

    E=Q×VE = Q \times V

    E=0.042×1.5E = 0.042 \times 1.5

  3. Perform the calculation:

    E=0.063E = 0.063 J

Thus, the energy transferred is 0.063 J.
