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

Question 2

If a - particle at rest decays into a neutron and a - , what is the total kinetic energy of the decay products? The masses of -, neutron, and - are 1197 MeV/c2, 940 MeV/c2, and 140 MeV/c2, respectively.
