Hi everyone I am là tiñö a student at Witwatersrand university and I'm a new member in PF.

1. If A is static and B is moving away from A at velocity v, from Einsteinian point of view, is A also moving away from B at the same velocity? If yes, is the similarity of movements and velocities of both A and B valid in every context? If B is experiencing a time dilation from the view point...

Does space expand only at the outer edges of the universe? What is the mechanism that creates more space particles? Is the huge volume of outer space pulling our universe apart? Please enlighten or comment. Kurt Ludwig

01.Velocity V of a stretched string depends on Tension T and mass per unit length M of the string. Create an equation for Velocity VUsing dimensional analysis. 02. A balloon is moving upward with velocity 36km/h, when it is 40m height from ground a particle dropped from it. (g=10m/s and there...

X-ray has enough energy to eject the electron in the atom, molecule etc. But in the x-ray diffraction electron does not eject, only oscillate with the same frequency as X -ray,why? Why does not x-ray eject the electron?

Please,I am working on the criticality calculation of an homogeneous finite cylindrical reactor core using four-group diffusion equations. I have been able to discretize the multigroup diffusion equations using the finite difference method(FED). But I am stocked on the iterative method to...
