Answer 1

Answer:

Step-by-step explanation:

When compression takes place in the medium, the density and pressure of the medium increase. This increase and decrease in density and pressure are temporary. Thus, compression is called the region of high density and pressure. Rarefaction is called the region of low density and pressure.

Answer 2

Answer:

Yes (you are 75 mi from epicenter) a minimum of 7.91 miles south.

Step-by-step explanation:

The spot in the drawing's upper right is the epicenter. From the epicenter, you are 45 miles south (down) and 60 miles west (left). Applying the Pythagorean Theorem, (leg)2 + (leg)2 = (hypotenuse)2, a right triangle is created.

x² = 60² + 45²

x² = 3600 + 2025

x² = 5625

x = √5625 = 75

You can feel the earthquake because it is within 80 miles.

You now travel x miles south (see image 2). You need at least 80 miles to separate you from the epicenter. You have a second right triangle with 80 for the hypotenuse, 60 for the legs, and 45 for y.

(y = 45)² + 60² = 80²

(y + 45)² + 3600 = 6400

(y + 45)² = 2800

y + 45 = √2800

y = √2800 - 45 = 7.91 miles.
