by classical theory I mean.. Newtonian mechanics with galilean relativity plus maxwell electrodynamics which together are not very logical, so we need special relativity ideas to get over the paradox of what happens to the magnetic field and attractive force between two currents when you run...
A somewhat simpler analogous paradox" is when you have 2 parallel beams of charge like cathode rays … in the frame comoving there is no magnetic attraction between parallel currents as in definition of amp. unit. Something is evidently wrong with classical theory if you try to apply it to both...
I had a lot of experience with such things and the question doesn't seem to be fully formed to me. Perhaps there is some extra info somewhere? Perhaps the solution revolves around making sure that the resulting function will be real valued as stated in question. That sets constraints between...
the divergence of said integral 1/ln x arises only very close to x=1. At that point log x is basically a simple straight line passing through a zero y=0 with gradient 1 or some finite value or whatever. So the reciprocal 1/ln x shoots off to infinity at x=1 in just the same way that y=1/x...
The problem could be a bit oversimplified. For example maybe his centre of mass is not at the pivot point and the guys arms up the rope give some fine adjustments. In another Pearson exam an assumption of 90 degrees of legs to rope was made also pretty random and not very convincing. Exam...
Hi I hope I can be helpful somewhere! And perhaps people here can help me resolve weird science stuff on internet such as that electric universe madness which has over a million views and I think it needs a good debunking.
