What is the ratio of the intensities of an earthquake P wave passing through the Earth and detected at two points 14 km and 44 km from the source?

Sagot :

Answer:

Explanation:

Intensity of a wave is inversely proportional to distance from source

I ∝ 1 / r

I is intensity , r is distance

I₁ / I₂ = r₂² / r₁²

ratio of intensity = 44² / 14²

= 9.87

intensity of earthquake of first place will be 9.87 times that of second place .
