    Where does the (5/2) come from in calculating thermal energy of diatomic gas

    Thanks, that makes sense now. Except, my book doesn't go through the derivation, it doesn't give the unit R just the ratio. What does it physically represent?

    Where does the (5/2) come from in calculating thermal energy of diatomic gas

    So I am doing a second year thermodynamics course and would like to know. Do we just have to remember (5/2)PV for a diatomic gas, why is it 5/2 and also what is it for a monatomic gas. Also would we have to remember more complex ratios for exams? Cheers

    Downwards Force acting on two mmebers and the tension in members.

    Ok, so the set up is that there are two memebers. Both are pivoted to a wall in line but at different heights but the join up on the other end. - - - - - - - - - - - the point where the join up is a...

    Integrating a Line Integral with Parametric Equations

    Homework Statement Evaluate the line integral ∫c y2 dx + 2xy dy, where C, is the path from (1, 2) to (2, 4) parametrised by r(t) = (t2 + 1)i + (2t2 + 2)j , 0 ≤ t ≤ 1 Homework Equations I worked out the velocity magnitude |v(t)| as 2t√5 The Attempt at a Solution I simply integrated...

    How do you determine if a force field is conservative?

    I'm doing an undergraduate ODE course and the question gives us an equation. F(x,y) = (2y, 2x) Then it asks "determine whether the force field F is conservative".0 How do we interpret (2y, 2x)? Is 2y, the x-component and 2x the y-component? Also what does it mean by conservative...

    Really with MATLAB, anyone.

    Homework Statement Hi, I really need help on this MATLAB assignment, I appreciate it. The Assignment requires us to plot a function that has two local maxima and no other critical points. I will present all my work here so you can see for yourself. Homework Equations The function is...

    Learning Math Differently: Understanding ODEs

    Alright, you said "differential equations exist to relate a function to itself", this is what I needed. I understand the fundamental difference now. I can build on this myself now, also I will check out all the topics recommended by homeomorphic. Better sooner than later. I don't plan on going...

    Solve this ODE (Newton's law of cooling)

    Homework Statement dT/dt = -k(T - T_m) T is the temperature of the body, T_m is the temperature of the surroundings, -k is some contant and t is ofcourse time Homework Equations no idea The Attempt at a Solution I tried solving this using first order linear ODE...

    Learning Math Differently: Understanding ODEs

    Hi, Usually, it takes a while for me to digest information, because I have a lot of filters in my mind and to remember and understand things I have to put all the new information in context. I have to have an interpretation of the content. For this reasons I am doing terribly in my ODE course...

    Career in Artificial Intelligence

    I know for a fact that all the relevant knowledge required to achieve this career, I will have to somehow get on my own. But I want to know which is the best "official" career path for me? Would it be electrical/computer engineering, neuroscience, or something else since my university does not...

    What is the trick to simplifying the Taylor series of 1/(1 + x^2)?

    it's at x = 0, I will try your method and post a pic.

    What is the trick to simplifying the Taylor series of 1/(1 + x^2)?

    The equation starts at B and this is my attempt. As you can see it soon complicates and doesn't look like what t should since I already know what the Taylor series of his function should look like. Is there some clever trick to it that I am missing? PS the series is centred around x = 0...

    How to integrate K/[(y^2 + K)^3/2] dy

    Never mind, I found out what I did wrong. I misused the product rule. What a simple mistake.

    Why is there never any electric field in a hollow conductor?

    I can understand that if there is no charge inside an object then the electric FLUX is zero. Meaning the net integral of field vectors with respect to the area will be zero. But that doesn't mean there are no field lines inside the object at all! does it? I thought it just meant that the number...
