An explorer is caught in a whiteout (in which the snowfall is so thick that the ground can not be distinguished from the sky) while returning to base camp. He was supposed to travel due north for 5.6 km , but when the snow clears, he discovered that he actually traveled 7.8 km at 50° north of due east. Determine a) how far he must now travel to reach the base camp?
b) In what direction must he now travel to reach the base camp?

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
