Use K_{eq} = \frac{[AB]}{[A][B]}

Oh, but I mean using polar coordinates for x^2+y^2+z^2 = r . Thanks for the the p chem help dextercioby.

I think just use dimensional analysis. The wave travels 2.5 m in 1.0 s so its velocity is 2.5 m/s. Divide this by 6 Hz (s^-1) and get 0.4167 m. Formula might be \lambda \nu = v .

Is that the combined gas equation? \frac{p_{1} V_{1}}{T_{1}} = \frac{p_{2} V_{2}}{T_{2}} Molar volume is the gas' volume divided by the moles of gas.

Your answers are correct but I am not sure about #3.

I mean del squared or laplacian. Oh, for the 2nd question: a 3D box with V = infinity outside box.

Im not sure. I just need to use the del operator on x^2+y^2+z^2.

I need to take the \nabla^2 of x^2+y^2+z^2. This is how far I got \begin{gather*} \nabla^2 = \frac{d^2}{dr^2} + \frac{2}{r} \frac{d}{dr} + \frac{1}{r^2}(\frac{1}{sin^2\theta}\frac{d^2}{d\Phi^2} + \frac{1}{sin\theta}\frac{d}{d\theta} sin\theta\frac{d}{d\theta})\\ \nabla^2(r^2sin^2\theta...

i'm pretty sure if it's 2 sided then you set it to \frac{\alpha}{2}

For the following: \begin{gather*} \hat{\Omega} = \frac{d}{d\theta}sin \theta \frac{d}{d\theta}\\function = e^{i\theta} \end{gather*} Use the operator on the function and is it an eigenfunction of \hat{\Omega}? Thanks. I don't think it is. There is also another problem with...

I don't know bracket notation or what a means, but I put it in the HW I turning in.

The problem I did like this used \begin{multline*} \Sigma F_{y}=F_{b}-F_{t}-F_{g}\\F_{g}=ma \end{multline*} with gravity and tension in the negative y direction.

The problem says: confirm that the 1st excited state wavefunction of a 1D HO given by the Hermitian equation H_{1}(y)= 2y y = \frac{x}{\alpha}, \alpha = (\frac{\hbar^2}{mk})^\frac{1}{4} is a solution of the Schrödinger equation and that the energy is \frac{3}{2}\hbar\omega...

Can some1 help me solve a first energy level Schrödinger (\psi_{1})with a the Hermite polynomial and also show that it equals to \frac{3}{2}\hbar \omega? I got as far as \newcommand{\pd}[3]{ \frac{ \partial^{#3}{#1} }{ \partial {#2}^{#3} } }\frac{\hbar^2}{2 m} \ \pd{\Psi}{x}{2} + V \Psi =...

Whats a Higgs boson field?
