Answer:
The ratio of the intensities is roughly 6:1.
Step-by-step explanation:
The intensity I() of an earthquake wave is given by:
<em>where P: is the power ans d: is the distance. </em>
Hence, the ratio of the intensities of an earthquake wave passing through the Earth and detected at two points 19 km and 46 km from the source is:
<em>where I₁ = P/4πd₁², d₁=19 km, I₁ = P/4πd₂² and d₂=46 km </em>
Therefore, the ratio of the intensities is roughly 6:1.
I hope it helps you!
Answer:
Step-by-step explanation:
Solving for the variable , given that :
We can first start start by subtracting from both sides of the equation:
Now, we can divide both sides of the equation by the coefficient of , which would be
:
Applying the fraction rule :
Then, apply the fraction rule
