Earthquakes have two kinds of waves, P waves and S waves. These waves may someday help scientist develop an early warning system for earthquakes. The P wave (also known as the primary wave) is the first wave, and the S wave (secondary wave) travels after it. Scientists can find the location of an earthquakes epicenter by subtracting the time that elapses between the P and S waves. A convenient way to find the epicenter is to use a graph like the one shown here.

Suppose that scientists record a P wave on a seismic device at 10 minutes. An s wave reaches the device at 15 minutes (5 minutes later). What is the distance between the recording device and the epicenter of the earthquake? Use the graph to determine your answer.

Answer :

Answer:

42

Explanation:

Multiply the difference by 8.4 to estimate the distance. ( kilometers )

P wave = 10

S wave = 15

Difference = 5

8.4 * 5 = 42

The initial wave (P wave) is less severe and moves faster, whereas the more damaging S wave moves slowly.

What is seismic waves?

When an earthquake happens, it sends forth energy waves known as seismic waves. It's similar to the ripples that occur when a stone is thrown into water.

Here, There are two types of waves: P waves and S waves.

P waves travel faster and are formed first; they go in the exact opposite direction from where the earthquake occurs.

S waves, or secondary waves, on the other hand, are slower and travel in a perpendicular direction.

When these waves are generated in particular facilities, scientists can detect them.

The difference between time = 15 – 10 = 5

From the graph:

=8.4×5

= 42

Thus, the initial wave (P wave) is less severe and moves faster, whereas the more damaging S wave moves slowly.
