WebThe gravitational binding energy of a sphere with radius is found by imagining that it is pulled apart by successively moving spherical shells to infinity, the outermost first, and finding the total energy needed for that. Assuming a constant density , the masses of a shell and the sphere inside it are: and. The required energy for a shell is ... WebAug 6, 2016 · For this application, we can wrap the output of DensityPlot [] (after some post-processing with Image []) on a sphere. One benefit to this approach is that DensityPlot [] takes care of scaling the spherical harmonics before feeding their values to the ColorFunction. For instance, to use ℜ ( Y ℓ m ( θ, ϕ)) as the texture, we can do this:
WebNov 7, 2016 · Current density is: j = I S. In the case of sphere the surface through which current if flowing is a function of x which means that the current density is also function of x. I think the current density for this problem is then: j(x) = I π ∗ (R2 − x2). This solution however gives singularities at j(R) and j( − R) so I am a bit sceptical. http://corysimon.github.io/articles/uniformdistn-on-sphere/
