Please help , i really need this done.

Answer 2

;~;

Answer 3

Okay, I'll try to help.

But you look at the numbers below it try to find the differences between the two to find the intervals in which this happened...

I did this in 7 or 8th grade or before that yeaaars ago! I'll come back to you later when I have found some old notes.. Sorry :c

Answer 4

But I remember measuring the graph to find the epicenter and looking at the y to find something, sorry I understand your plight! Just spam the mathematics section, everyone is there. But I'll try to help~!

Answer 5

should i try posting it there too? :O idk i dont wanna make anyone mad at me :)

Answer 6

No, someone posted about bias there and I answered it, one person asked about protons, i answered it. It's okay, just go there! Someone will help if not, who cares, just try :)

Answer 29

wrong subject sorry ._.

Answer 30

sorry you were listed under online for this subject.

Answer 31

~groans~ guuhhh

Answer 32

do you remember if p waves come first, or s waves

Answer 33

its really easy, i did this in my freshman yr 2 yrs ago
p waves = primary waves, so they come first. s waves = secondary waves. just put it as close as you can to a time (ex. P wave arrival= 8:07, s wave arrival= 8:09) Time difference = greater time- lesser time. (ex. 8:09-8:07=2 min) distance to epicenter= use the time difference and the chart to locate the distance to the epicenter (ex. 2 min= 1275 km)
hope this helped

Answer 34

so the second one would be 3 mins? and the third one is 1 min?

Answer 35

You want to look at the point where each wave starts. In the first graph, the p wave (the first wiggly line) begins at 8:07 and the s wave (the second wiggly line) starts at 8:09. When you subtract those times you get 2 minutes for your answer. The second graph p wave starts at 8:06 and the s wave starts at 8:07 and 15 seconds, or 8:07:15. When you subtract those, remember that 15 seconds is 1/4, or 0.25, of one minute. So the second difference would be 1.25 minutes.

Answer 36

So using that method, what would you say is the difference for the 3rd waves?

Answer 37

PENGY! :D That makes sense... uhm.. 0.02, so 2 mins?

Answer 38

yay! now what about the graph?

Answer 39

The graph will give you the distance, just find the time for each graph on the left side and draw a line straight right to the line. Then draw a line straight down to the x-axis and wherever you are is the distance.

Answer 40

For example, for the first one you find two minutes and follow it over. The line crosses just a little more than halfway between 1200km and 1300km. This means your answer should be slightly over 1250km. I would personally put 1260km. I just hope your teacher isn't overly nitpicky on the graph number.

Answer 41

What about the map? I can't seem to get it done -.- i'm making them 'too small'

Answer 42

This is amazing how I am in IDVA and I have the exact same question. I think I will report you. Thanks for your contact info! Cheater! No one listen, all the answers in are the course, so she is too lazy to look!

Answer 43

Bugger off, Shadowman. struggling to understand the course=/= lazy so Gfys
