AI Thread Summary

In an LC circuit with an initial charge Q0 of 18 C and current I at 0, the equilibrium charge on the capacitor occurs when energy is equally distributed between the inductor and capacitor. The potential drops around the circuit can be analyzed using Kirchhoff's voltage law, which leads to the equation relating charge and current. At the moment energy is shared equally, the charge on the capacitor can be calculated using the relationship between energy stored in the capacitor and inductor. The discussion emphasizes the importance of applying circuit equations to determine the charge at this specific moment. Understanding these principles is crucial for analyzing LC circuits effectively.

Thread 'Light speedup question'

If light travels in a wave, couldn't we "speed it up" by making it travel in a straight line?

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
