Atomic nuclei consist of protons and neutrons‚ which have a positive or negative charge. Electric forces are repulsive between similar charges‚ so there must be a force much stronger than electromagnetism keeping them together. This force is called the Strong Nuclear Force‚ and it is about a hundred times stronger than the electromagnetic force. Its strength allows it to hold a nucleus together‚ despite the desire of the electromagnetic force to thrust it apart. Despite its relative strength‚ the

Fluid mechanics is the branch of physics that studies fluids (liquids‚ gases‚ and plasmas) and the forces on them. Fluid mechanics can be divided into 1) fluid statics‚ the study of fluids at rest; 2) fluid kinematics‚ the study of fluids in motion; 3) fluid dynamics‚ the study of the effect of forces on fluid motion. Fluid Mechanics Overview Fluid is a substance that is capable of flowing. It has no definite shape of its own. It assumes the shape of its container. Liquids and gases are

elGauss’ Law AP Physics C Electric Flux Let’s start be defining an area on the surface of an object. The magnitude is “A” and the direction is directed perpendicular to the area like a force normal. A E Flux ( or FLOW) is a general term associated with a FIELD that is bound by a certain AREA. So ELECTRIC FLUX is any AREA that has a ELECTRIC FIELD passing through it. We generally define an AREA vector as one that is perpendicular to the surface of the material. Therefore‚ you can

Introduction Low-dimensional (low-D) quantum spin systems are of great interest in solid state physics due to the wealth of exciting phenomena originating from the interplay of reduced dimensionality‚ competing interactions and strong quantum fluctuations. Recently‚ great interest and controversy has surrounded the proposal that the spin S = 1/2 moments

Throughout the story Alice meets a strange cast of characters‚ each one relating to a quantum function. Through these characters Alice‚ and the readers‚ gain a greater understanding of quantum mechanics.

Introduction The wave equation is an important second-order linear partial differential equation for the description of waves – as they occur in physics – such as sound waves‚ light waves and water waves. It arises in fields like acoustics‚ electromagnetic‚ and fluid dynamics. Historically‚ the problem of a vibrating string such as that of a musical instrument was studied by Jean le Rond d’Alembert

There will be a net force from the pressure to push the piston back out. Since gas has mass it can support oscillations and waves. 2.2 Traveling Sound Waves
