Homework Statement

Homework Equations



I am not sure. Maybe Archimedes's Principal and f=ma. This could possibly be a control volume problem so also the continuity equation or the momentum equation for control volumes.

The Attempt at a Solution



This is in my first assignment in my aerodynamics class. It was supposed to be a review of Fluid Mechanics 1. All the problems before it for control volume problems, but the statement says it is a hydrostatic problem/rigid body problem. So I'm not sure if we are supposed to use control volume analysis or not. Regardless I'm confused on how to start. I can't think of an equation that would some how give me the angle the water level would make. If anyone could just give me an initial hint or point me in the right direction, that would be awesome.

Thanks!

I thought about it more, and I'm thinking that the surface of the water will be perpendicular to the net force acting on the body. Is that correct?

Thread 'Need help understanding this figure on energy levels'

This figure is from "Introduction to Quantum Mechanics" by Griffiths (3rd edition). It is available to download. It is from page 142. I am hoping the usual people on this site will give me a hand understanding what is going on in the figure. After the equation (4.50) it says "It is customary to introduce the principal quantum number, ##n##, which simply orders the allowed energies, starting with 1 for the ground state. (see the figure)" I still don't understand the figure :( Here is...

Thread 'Understanding how to "tack on" the time wiggle factor'

The last problem I posted on QM made it into advanced homework help, that is why I am putting it here. I am sorry for any hassle imposed on the moderators by myself. Part (a) is quite easy. We get $$\sigma_1 = 2\lambda, \mathbf{v}_1 = \begin{pmatrix} 0 \\ 0 \\ 1 \end{pmatrix} \sigma_2 = \lambda, \mathbf{v}_2 = \begin{pmatrix} 1/\sqrt{2} \\ 1/\sqrt{2} \\ 0 \end{pmatrix} \sigma_3 = -\lambda, \mathbf{v}_3 = \begin{pmatrix} 1/\sqrt{2} \\ -1/\sqrt{2} \\ 0 \end{pmatrix} $$ There are two ways...
