About 1350 W/m2 of electromagnetic energy reaches the upper atmosphere of the earth from the sun, which is 1.5  1011 m away. Use this information to estimate the average power output of the sun.
 
  A) 1  1026 W
  B) 2  1026 W
  C) 3  1026 W
  D) 4  1026 W

Question 2

A flat coil having 160 turns, each with an area of 0.20 m2, is placed with the plane of its area perpendicular to a magnetic field of 0.40 T.
 
  The magnetic field changes uniformly from 0.40 T in the +x direction to 0.40 T in the -x direction in 2.0 s. If the resistance of the coil is 16 , at what rate is power generated in the coil during this change?
  A) 5.0 W
  B) 10 W
  C) 15 W
  D) 20 W
