The rate of energy flow per unit area of an electromagnetic wave has an average value of 0.695 W/m2. The wave is incident at right angles upon a rectangular area measuring 1.5 m by 2.0 m
How much total energy falls upon this rectangle each minute? (?0 = 8.85 × 10-12 C2/N ? m2, ?0 = 4? × 10-7 T ? m/A, c = 3.0 × 108 m/s)
A) 130 J
B) 160 J
C) 190 J
D) 220 J
E) 250 J
