Homework Statement [PLAIN]http://img504.imageshack.us/img504/4985/capturewm.jpg Homework Equations N/A The Attempt at a Solution This is more of a conceptual question so I need a little help knowing what kinds of things to look for.

Thanks for the clarification. Just calling it what the prof does. I also looked around on the web at examples and thought that it wasn't quite the same. Thanks again!

In the attachment below, I have a picture of both an original wheatstone bridge and my attempt at converting it to a more familiar looking circuit. Is what I did correct/even possible? I just want to get a better understanding of these types of circuits. Thank you for your time!

To be honest, there is nothing much to C. It basically is just a shell that you use in order to do other things. You should specialize with a certain set of API's, whether it be Windows or Linux (or others as well). C is cross platform, but the libraries don't always tend to be the same...

To me, it just looks like N is referring to the whole collection of numbers in general. I don't think your prof is looking for you to specify an actual value of N, just an idea of what to do with your program. Welcome to cryptic programming directions 101...it has only just begun

Well, you could always just plug your solutions into a calculator. :) But really there is only 1 point on the circle that sin(x) = 1. This is at pi/2. But the function you are given multiplies whatever argument you pass to sin by 4. In order for this to come out correctly, you need to divide...

r is defined as being the distance between the two point masses. I might be wrong, but for this problem, would you not just use the distance from Earth as r?

After an elastic collision, no kinetic energy is lost. So basically this is a system in which the energy will be constant (not realistic). Also I just looked at what they gave you. Knowing the given data kind of throws that switch about which equation to use, at least for me.

You do when you plug it in, but the square should make it positive anyway. And I made an error in that equation, I am sorry, the velocities are supposed to be squared. MY MISTAKE!

5.3 is the answer I get. .5*m1*v1^2 + .5*m2*v2^2 = .5*m1f*v1f^2 + .5*m2f*v2f^2 All of the .5's cancel out. Be sure to convert cm to m. Note that m1f = m1 and m2f = m2 in this case, because the problem says nothing about mass being lost.

Sure does, thanks for all your help.

Just a quick clarification, sorry. Would I be using the surface area of my body, or the surface area of the earth? I would almost think the surface area of my body would be negligible.

Good point about where I am standing. I guess my prof overlooked that part of the question. But let's assume I am at the equator. Would I be using the equation B * A? B being the force of the Earth's magnetic field, and A being my body's surface area?

When you get down to the answer of None of these factors are being added, they are being multiplied. So when you go down the path of You should now be expecting an answer to have various factors being added or subtracted, which is expected. Not all polynomials can be factored the same way...
