Consider the particle in a one-dimensional box (0 s x s l). assume a term is added to the hamiltonian of the form: πχ v(x)g sin sketch the potential and the expected eigenfunction (small g). in the limit of small g, find the second order correction to the ground state energy 2. (50 points) for a diatomic molecule rotating in free space, the hamiltonian may be written: 12 21 where l is the total angular momentum operator, and i is a constant (the moment of inertia). remember (0 eigenfunctions for the θ π; 0 φ 1 state are: 2π) and d-sin θ d θ d φ.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

there are no contact forces mentioned on the list of choices that you've provided.
