What is the ratio of the intensities of an earthquake P wave passing through the Earth and detected at two points 14 km and 41 km from the source? And what is the ratio of the amplitudes?
Added by Brenda M.
Step 1
Given: Distance 1 (d1) = 14 km Distance 2 (d2) = 41 km Using the formula for intensity (I) being inversely proportional to distance squared: Ratio of intensities = (I1/I2) = (d2^2/d1^2) = (41^2/14^2) = 1681/196 = 8.5816 Show more…
