The magnitude of the Poynting vector of a planar electromagnetic wave has an average value of 0.939 W/m2.
 
  The wave is incident upon a rectangular area, 1.5 m by 2.0 m, at right angles. How much total electromagnetic energy falls on the area during 1.0 minute? (c = 3.0 x 108 m/s, 0 = 4  10-7 T  m/A, 0 = 8.85  10-12 C2/N  m2)
  A) 210 J B) 170 J C) 340 J D) 250 J E) 300 J
