Set 9 Problem 4 A seismulogist measures the intensity of the 1) wave from an earthquake to be 2.31 MWMm2 at a distance of 80 km from the source. a. Find the intensity of the wave when it passed a point just 3 .6 km from the source. Reset All In what manner does the intensity of a wave decrease with distance from its source? Assume the wave energy radiates unifomly outward with spherically symmetry (i.e. the intensity is the same at all points on a sphere equidistant from the source). l7. Find the total power of the wave passing through an area of 4.3 m2 at a distance of 3.6 km from the epicenter. DD? W w Reset All
