Densities are useful in summarizing the total charge, current, mass, or whatever that is present in a distribution. While the ratio of the quantity over the region of space may seem unimportant, many fields of physics use these densities:...
sorry I'm not a physicist or student in this is not homework I was just thinking about this. say you have a spherical Mass of a certain density I'm thinking say planet-sized and then tangent to the surface of that sphere you have a circuit running say 100 kilometers...
They can trace trajectories that can cross any point in the area such that the number of possible trajectories is the number of points in the area, which is just the area itself. Which means that the current density JJ is just the flow jj divided by the areaextension of the finish-area...
General Relativity. In the theory, a singularity describes the center of a black hole, a point of infinite density and gravity within which no object inside can ever escape, not even light. The current knowledge of physics breaks down at the singularity and can't describe reality inside of ...
What is magnetic field intensity in physics? What is an induced magnetic field? What is the simplest quantum field theory? What is superstring theory? What is the string field theory? What is electromagnetic energy? What is a non-uniform magnetic field?
electric charge.Chargeis a property of matter--just like mass, volume, or density. It is measurable. Just as you can quantify how much mass something has, you can measure how much charge it has. The key concept with charge is that it can come in two types:positive (+) or negative (...
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.
According to the potential energy definition, it is the energy that is stored in an object. Know what is potential energy, potential energy definition, its types and examples at BYJU’S - The Learning App.
Water currents can be found in streams, rivers and oceans throughout the world. Water current is the rate of movement in the water, and ways to describe water current include its speed and direction. There are different types of water currents which beha
Wherever a loose bed of sand is subject to sufficiently strong winds, aeolian dunes form at predictable wavelengths and growth rates. As dunes mature and coarsen, however, their growth trajectories become more idiosyncratic; nonlinear effects, sediment s
