    Solving Cylinder Problem: Calculate Work Done in KJ

    it doesn't state that is isothermal ho it is written above is exactly how the problem is written, but I will attempt it that way thank you.

    Solving Cylinder Problem: Calculate Work Done in KJ

    no it does not state that it is an adiabatic, I considered that formula but I'm not sure as to how I would use it because there is a beginning volume and an ending volume. I'm still pretty confused it has been a while since Thermo I this is just a review for Thermo II. I appreciate the help thanks!

    Solving Cylinder Problem: Calculate Work Done in KJ

    Hello I am having trouble with this problem I was wondering if anyone could help me out here goes, During some actual expansion and compression process in piston-cylinder devices, the gases are observed to satisfy the relationship PV=C, where n and C are constants. Calculate the work done in...

    How Does an Electron Move in the Field of a Uniformly Charged Ring?

    Ok this is what I got Ke(Q/(x^2+a^2) <--- square root over the donominator. Q= 12.0 nC a= 25.0cm => 0.25m r= 10.0cm => 0.10m the answer given is 1.19x10^7, I keep getting 1.488x10^12, however I see where I wen't wrong because Ke=8.99x10^9 Nm^2/C^2, so this means I have to convert 12.0 nC to C...

    X^2+2 were integrated it would be 1/3x^3

    well it's A*r^(1/2), for example a+bt+bt^2= a^2/2*bt^2/2*bt^3/3, I'm just not good w/ fractions, would it be Ar^(3/2)/(3/2)? or (3/2)Ar^(3/2)?

    X^2+2 were integrated it would be 1/3x^3

    Hello I'm trying to integrate Ar^(1/2) would the answer be? well I know if X^2+2 were integrated it would be 1/3x^3 I just get confused when it's fractions would it be (3/4)Ar^(3/2)?

    How Does an Electron Move in the Field of a Uniformly Charged Ring?

    ok here goes, A uniformly charged ring has a radius equal to 10.0cm and a total charge of +12.0nC. An electron is placed on the ring's axis at a distance of 25.0cm from the center of the ring and is constrained to stay on the axis of the ring. The electron when it reaches the center of the...

    How Do You Determine the Electric Potential Outside a Charged Sphere?

    Here's the question: A sphere has a charge distributed throughout it such that the charge density goes as p(r)=Ar^(1/2). A=0.0200C/m^(7/12). The sphere has a radius of 2.00m, determine the electric potentioal at 3.00m from the center of the sphere? well I got the charge density which is...
