2.) As observed from the Earth, the intensity of sunlight is 1361 W/m. The permittivity of free space (the permittivity of the vacuum) is 8.854x10-12 F/m. Also, the permeability of free space (the permeability of the vacuum) is 4x10-7 H/m. Finally, the Earth is 1.496108 km from the Sun. (a) Calculate the speed of light in the vacuum. (b) Calculate the average energy density of sunlight. (c) Calculate the average electric energy density of sunlight and the average magnetic energy density of sunlight. (d) Calculate the root-mean-square electric field and the root-mean-square magnetic field of sunlight. Calculate their maximum values also. (e) Calculate the power output of the Sun.
