The paradox is resolved through the big bang theory, which puts forth that the Universe is dynamic, non-uniform and (probably) finite.
a) Explain the magnetic effects of current? b) Do the diagram to show the direction of motion of the conductor:
Mass of the system is same. since, p=mv momentum remains same
Vector Direction The significance of 'direction' could be seen in the dissimilarity among velocity and speed. In physics, speed is a pure scalar or something along with a magni
