We demonstrate a very general mathematical and physical expression of the rotation speed at the end of the galaxy (far from the vast majority of the galaxy’s baryonic mass) obtained from General Relativity without non-baryonic matter. We show the excell
This model had a number of major problems, these included the following: 1. Since any charged particle will radiate energy when accelerated, an orbiting electron would continually lose energy, and hence spiral down into the nucleus emitting a continuous spectrum of light. Equating the force due ...
A mirror is an object that reflects the light incident on it. There are 3 types of mirror, i.e. convex mirror, concave mirror and flat mirror. The mirror formula is, 1f=1v+1u where, f is the focal length v is the image distance from the pole of ...
Which one will touch the ground first? Explain why by using the concept of terminal Why do all free falling objects have the same acceleration? A 60 kg skydiver falls through the air with a force of air resistance of 200N ...
