What is the difference among Free Electron Theory and Band Theory of solids?
Free Electron Theory:
This theory says that, metals conduct electricity due to the presence of free electrons in it. The outermost shells of metal atoms will be loosely bound with their nucleus. So the electrons in it are free to move anywhere in the solid.
These electrons are known as free electrons and these electrons are responsible for the conduction of electricity.
Conservation of angular momentum The overall angular momentum of any closed system remains constant. There are many other laws which deal with particle physics, as conserv
Vertical Circular Motion A mass is in circular motion within the vertical plane. We show the weight and force exerted through the tension within the string.
A UNIFORM ROD OF MASS M, HINGED AT ITS UPPER END, IS RELEASED FROM REST FROM A HORIZONTAL POSITION. WHEN IT PASSES THROUGH THE VERTICAL POSITION FIND THE FORCE ON THE HINGE.
Figure shows a simple model of spring-mass system. The mass is released from the rest with the springs un-stretched. It's downward acceleration is a=9.81 - 15.24y m/s 2 where y is
