To find the epicenter (the point on the earth's surface where an earthquake begins) during earthquakes, one need to view the seismogram (a record of the ground motion), and at least two other seismographs recorded for the same earthquake. Other instruments such as a map, a compass for sketching circles on the map, a ruler, and a pencil will also be used.
The following are the steps of the triangulation process in the correct order to find the epicenter during earthquakes:
Step 1: Subtract the time of P wave arrival from S wave arrival.
Step 2: See what the time difference is equal to in distance on a seismic wave chart.
Step 3: Draw circles representing the distances from at least three seismograph stations to the epicenter on a map.
Step 4: Find the point where all 3 circles intersect, and you've found the earthquake's epicenter.
Just a brief history of the Illiad:
This story is all about how Ilium, otherwise known as Troy, fell. It is a Greek poem attributed to Homer. The story is set during the Trojan war near the end of it. it all started when Paris, stole Helen from Menelaus who is the King of Troy.
Attached is the re-typed summary and the answers to your questions. I hope this helps.
Answer:In a coal deposit, which is heating up the concentration of hydrocarbons, together with the concentrations of carbon monoxide and hydrogen, increase, followed by an increase in temperature, and decrease as the temperature decreases
Explanation:
The answer is National security because the citizens need to know that they are being protected, and usually also how they are being protected. But the government often needs so measure of secrecy in order to protect National Security. If the government were to tell citizens exactly how they were being protected and someone posted it onto the internet it would severely compromise that protection. However people do not generally seem to understand that and tensions become heated between the two groups. Both sides reasons are perfectly legitimate, but one outweighs the other by knowledge. The answer is B.
