computer simulation equation graphs maps

2. taramgrant0543664

If he wants to show the location of something occurring then wouldn't the obvious choice be a map? The computer simulation could show what the earthquake felt like or how it was triggered or how it affected the area in which the earthquake occurred. The graphs could show trends and an equation could show the relationship between different trends but nothing else focuses only on location of the earthquake.

so a map yours saying @taramgrant0543664

4. taramgrant0543664

I would assume so

5. anonymous

could you help me with one more @taramgrant0543664 <33333

6. taramgrant0543664

Sure

Cameron was given the following series of observations. Which represents a theory?

9. anonymous

Rocks are found on the ocean floor. Rocks can form volcanoes. Rocks break down over time. Certain types of rocks form deep inside Earth.

So there are some facts in here so we can distinguish between known facts and eliminate those. We know that there are rocks on the ocean floor and we know that there are certain types of rock on the ocean floor. So we can eliminate those right off the bat. As for the two left which one do you think it is?

12. taramgrant0543664

Sorry just realized I caused a slight error! So we know the first three are facts cause we know for sure those are true. The last one we can just assume that the there are rocks deep inside. I had just assumed that that was a known fact which should have clued me into it being the theory!

13. anonymous

so which one would it be according to your explanation @taramgrant0543664

14. misssunshinexxoxo

D is the best choice because the representation would be on a map

15. taramgrant0543664

Certain types of rock form deep inside Earth would be your answer for that one

16. anonymous

can you help me with more @misssunshinexxoxo

A pair of scientists proposes two different theories to explain the same set of observations. Which of the following best explains the value of these competing theories? Competing theories can be a source of new, testable ideas. Competing theories are necessary to transform a theory into a law. Competing theories generate controversy that helps popularize ideas. Competing theories allow scientists to combine the most interesting aspects of both theories.

19. taramgrant0543664

I would go with C in my opinion

20. misssunshinexxoxo

D is the best choice

21. anonymous

d was wrong @misssunshinexxoxo

Which best describes how equations are used in science? An equation is a type of graph. An equation is a type of theory. Equations use symbols to represent data. Equations show the locations of distant objects.

Okay, the “don’t give the answer” policy is hard sometimes. Consider this… Equations are ways of expressing the value of some concept relative to how one or more other variables change. Given that math is the often considered the language of most sciences. Equations help us determine how changes in one thing lead to predictable changes in other things.
