    Calculating charge dissipation given two hanging masses

    Homework Statement Two hanging masses have an identical charge and create an angle theta from the vertical. If they start losing their charge and have an instantaneous velocity of XX m/s(given), find the rate in which they are losing the charge. Homework Equations Coulumbs Law The...

    How Does Friction Affect Spring Compression and Energy Loss?

    remember the delta's are (final - initial) and the mass comes to a complete stop(i.e. it's final kinetic energy is zero)

    The potential energy of two atoms-

    Homework Statement The potential energy of two atoms with a radius r is written as- U(r)= -4Uo[(Ro/r)^12 -(Ro/r)^6] Find the radius at stable equilibrium and the work required to separate the two atoms. Homework Equations F(r) = -dU(r)/dr The Attempt at a Solution If...

    How Does Friction Affect Spring Compression and Energy Loss?

    Set up your work-energy theorem so that everything is in your system. So: 0 = deltaKtrans + deltaThermal +deltaUspring You only have one unknown, the 'x'(or distance) value in your deltaThermal and deltaSpring expression. Solve for that x and plug in your knowns. Once you solve for x, plug...

    1. Burning butane (C4H10) produces gaseous carbon dioxide and water.

    I'm not following some of your notation, but here is what I would do- Find out how many moles of Butane you have, which I think you did. Next, use the enthalpy of combustion to find out the total amount of energy you can get from 1 Kg of butane. Next, use that value as your 'q' in your...

    Courses Required Pre-Calc knowledge for a Calculus course?

    I did pretty much the same thing... right into Calc. without ever taking precalc and it had been ~6 years since I had taken trig. I'd recommend Ch. 1, 3 and 4 to begin with... logs pop up almost right away(in my book anyway). Another thing you can't escape is Trig... take the time and make...
