A.) We use the famous equation proposed by Albert Einstein written below:
E = Δmc² where E is the energy of the photon Δm is the mass defect, or the difference of the mass before and after the reaction c is the speed of light equal to 3×10⁸ m/s
b) The actual energy may be even greater than 3×10⁶ Joules because some of the energy may have been dissipated. Not all of the energy will be absorbed by the photon. Some energy would be dissipated to the surroundings.
The square plates of a 3000-pF parallel-plate capacitor measure 40 mm by 40 mm and are separated by a dielectric that is 0.29 mm thick and completely fills teh region between the plates.
The turns ratio is equal to the voltage ratio. Let n1 and n2 be the primary and secondary turns. Then 5850V/120V=n1/n2 48.75=2680/n2 n2=2680/48.75 n2=55
