Answer:
Both these motions are caused by the Gravitational force of earth.
Explanation:
Both these motions are caused by the Gravitational force of earth.
Energy of one photon = kinetic energy of photoelectron + work function energy of metal.
Intensity of radiation is proportional to the number of photons arriving per second
Answer:
Our modern ideas about government were influenced by many different ideas and traditions. The biggest influence came from their British heritage. (Remember the colonists WERE British until the American Revolution!)
Newton's first law states that an object at rest remains so until acted upon by external forces or an object in motion does so without accelerating (that is, at constant speed).
