    Deriving the coefficients a and b in the Van der Waalls Equation of State

    I've looked in my textbook and asked my fellow classmates, but I have had no luck in figuring out how to derive these coefficients. Can anyone tell me how I would go about doing this?

    Can You Derive a Mathematical Formula from This Data Pattern?

    Need to analyze the pattern and create a formula if possible out of the data below. Inputting the first column and outputting the second. 1 1 2 1 3 3 4 1 5 3 6 5 7 7 8 1 9 3 10 5 11 7 12 9 13 11 14 13 15 15 16 1 Only thing I got that is on powers of 2, it should be 1. If...

    Deriving the 2nd Equation on Wave Longitudinal Velocity

    i've found 2 equations on longitudinal velocity of waves v=lambda*freq and v=Lsqrt(k/m). is the 2nd equation derived from the 1st? if not how do you derive it? thx.

    Deriving Acceleration from Potential Energy?

    I have a known potential energy, V, expression: V(x,y,z) = α·x + β·y2 + γ·z3 I'm given: @(0,0,0), v = v0 and then asked to find v at (1,1,1). I can determine v from Conservation of Energy: v2 = v02 - (2/m)·(α + β + γ)2 In general, what is the expression for the accelerations...

    Deriving Electric Field Independence on Negligible Separation

    I read from a website that the electric field is independent of the separation between the plates if the separation is negligibly small. But how to derive this?

    Deriving Wien's Displacement Law from Planck's Law

    Basically this problem is to derive Wien's displacement law from Planck's law. Specifically: a) Show that there is a general relationship between temperature and λmax stating that Tλmax = constant and b) Obtain a numerical value for this constant [Hint: Start with Planck's...

    Deriving an equation for the density of air

    First of all, I'm new to this forum, so please excuse any newbie etiquette errors I have made =) My problem is this: I'm doing a lab report on an experiment where we attempted at measuring the density of air. I won't go to the details, but basically we just measured air on different pressures...

    How Do You Derive the Equation for Drag?

    could someone tell me how to derive the equation for drag or send me a site that can do it. Fd = [Coefficient of drag * density * Area (cross-sectional)*v^2 ] / 2

    Doppler Shift: Deriving a Formula for Both Moving Objects

    My book derives two formulas for Doppler shift. One for when the source moves and one for when the observer moves. What about when both are moving? I tried deriving it myself... but I couldn't :( If you want, you could just give me a hint on how to derive it.

    Does anyone have any good tips on deriving equations?

    I'm very lost ! First off thanks to HallsoIvy and AD for answering my last question. However I am still having a difficult time with the last question. I know that we are suppose to try these problems before we post…but I am having a horrible time understanding how to derive equations. I am at...

    Deriving 'G' from E=mc^2 and Gravitons

    What does the unit and magnitude of constant 'G' mean, and what is its relation with graviton? ANY OPINION? Here is how i see it: E=mc^2 c^2=E/m where E=W=Fr (r stands for radius or distance or ‘s’) therefore c^2= Fr/m therefore c^2= c^2----when forces interact the forces hold true...

    Deriving atwood's gravity formual

    I have always been curios to how Atwood derived his formula a=g(m2+m1)/(m2-m1) to get gravity. Does anyone know how he did it? I have read that he used Netwons f=ma but I personally could not find a way to do this using Newtons f=ma. Thanks.
