The Biot–Savart law [4]: Sec 5-2-1 is used for computing the resultant magnetic flux density B at position r in 3D-space generated by a filamentary current I (for example due to a wire). A steady (or stationary) current is a continual flow of charges which does not change with time and the charge neither accumulates nor depletes at any point.
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field.
If the two forces are F and −F, then the magnitude of the torque is given by the following formula: = where is the moment of couple; F is the magnitude of the force; d is the perpendicular distance (moment) between the two parallel forces
An example is boron carbide, whose formula of CB n is a variable non-whole number ratio, with n ranging from over 4 to more than 6.5. When the chemical compound of the formula consists of simple molecules , chemical formulas often employ ways to suggest the structure of the molecule.
For years, Allen Brooks promised his mother Sarah Pearl Brooks he would finish college. In December 2024, the 60-year-old made his late mother's wish come true when he graduated from Alabama A&M ...
Visulization of flux through differential area and solid angle. As always ^ is the unit normal to the incident surface A, = ^, and ^ is a unit vector in the direction of incident flux on the area element, θ is the angle between them.
In the United States, around 2.3 million households are home to reptiles, including turtles. Here's what the reptile can and cannot eat.
Young’s raw numbers stand out: 22.5 points, 11.4 assists — almost identical to Magic Johnson’s points and assists in his last MVP season in 1990. But that shows you how numbers lie. Ha!
