The energy of a photon is given by E = h * f, where h = 6.63 x 10^-34 J·s. Thus, E = 6.63 x 10^-34 * 6 x 10^14 = 4.14 x 10^-19 J.

The energy of a photon is given by E = hc/λ. Using h = 6.626 x 10^-34 J·s and c = 3 x 10^8 m/s, E = (6.626 x 10^-34)(3 x 10^8)/(500 x 10^-9) = 3.98 eV.

The energy of the ground state of a hydrogen atom is -13.6 eV.

The energy released in nuclear fusion is generally more than that released in nuclear fission, making it a powerful energy source.

The energy released in nuclear fusion is primarily due to the mass defect, where the mass of the resulting nucleus is less than the sum of the masses of the individual nucleons.

U = 1/2 * C * V² = 1/2 * (10 × 10^-6 F) * (50 V)² = 0.0125 J.

The energy stored (U) is given by U = 1/2 CV². Thus, U = 1/2 * 4μF * (12V)² = 288μJ.

Using the formula U = 1/2 CV², we have U = 1/2 * 5μF * (10V)² = 0.5mJ.
