Ohm’s law states that the current through a conductor is directly proportional to the voltage across the conductor, provided the temperature... View Article
In a reverse photoelectric effect, the production of X rays electrons accelerated by a high potential difference are impinged on a metal surface... View Article
Positive charges produce an electric field that is directed away from the charge in all directions. Negative charges produce an electric field... View Article
The photoelectric effect cannot be explained by the wave model due to the following reasons: The energy of a wave increases with an increase... View Article
The moment of inertia is the measure of the required force to rotate an object. The value of the moment of inertia can be manipulated by either... View Article
Inertia is a force which brings all objects to a rest position. Fast-moving objects have more inertia than slow-moving objects. There would... View Article
Inertia is the tendency of an object to remain unchanged. Translational inertia measures the resistance offered by the object in motion when it... View Article
