At one location on the Earth, the rms value

At one location on the Earth, the rms value of the magnetic field caused by solar radiation is 1.80 μT. From this value calculate
(a) The rms electric field due to solar radiation,
(b) The average energy density of the solar component of electromagnetic radiation at this location, and
(c) The average magnitude of the Poynting vector for the Sun’s radiation.
(d) Compare the value found in part (c) To the value of the solar intensity given in Example 34.5.
