I have two equations:

1: $\displaystyle y=\frac{0.0029}{\sqrt{k}}$

2: $\displaystyle y=\frac{0.0060}{\sqrt{m}}$

Which variable has a greater effect on $y$? i.e., does doubling $m$ have a greater effect on $y$ than doubling $k$? How do I describe/prove that?

Thanks!

(I asked a similar question previously, here. However I feel that the square root nature of this question makes it an entirely different question, and so I've posted a new question.)

    Why not try it and see? Pick some $m$, see the effect of doubling it, then do the same with $k$, see if you can work out what's going on.2011-05-22

    Try and plot some of those graphics for differents $k$ and $m$ at wolframalpha.com, so you can actually see what is happening.2011-05-22

    you need to start accepting, and/or voting for answers to questions you've asked: people here put a lot of time and effort providing answers to questions. All we ask is that you accept solutions and/or vote up those you find helpful. I realize that you're somewhat new here, but you've asked 5 questions now, all answered, but have provided no feedback.2011-06-02

    Well, you want to compare $k$ and $m$, right?2011-05-22
