First I drilled holes of different diameters into bottle caps. Then, I held a 2L bottle with the bottom cut off, upside-down, in place with a clamp stand and filled it around 2/3 of the way up with water, covering the hole in the cap. I swirled the bottle to create a vortex and once the vortex...
Homework Statement
In a water vortex formed in a plastic bottle, what is the relationship between the angular speed of the water and the diameter of the hole in the cap? I would have expected that according to the conservation of angular momentum, the smaller the hole the faster the water speed...
Hi can anyone help me? I am trying to calculate the evolution of ψ(x,t) (a value which I have calculated numerically for my specific problem), and I would need to find another state; phi(x,t), which has changed over time. Can someone explain to me how to do this please. Do I use the Schrodinger...
