The electric field of an infinitely large, thin plane of positive charges with uniform surface charge density is determined using Gauss’s law. The electric field is normal to and directed away from the plane and can be found by using a...

When Gauss-Jordan elimination transforms a matrix representing an inconsistent system of linear equations to reduced row-echelon form, a matrix row containing all zero coefficient entries and a non-zero constant entry is produced,...

In this video, students learn how to describe the cross-sections of a right rectangular pyramid by slicing at different angles. They are introduced to the concept of cross-sections and how they result from cutting a 3-dimensional shape...

When solving a system of linear equations with a single solution, we get a unique value for each variable. But how do we recognize when a system of equations has infinitely many solutions or no solutions?

In this video, students will learn how to describe the cross-sections of a right rectangular prism by slicing at different angles. They will understand the concept of cross-sections as the two-dimensional shape that results from cutting...

AP Physics C: Electricity and Magnetism review of Electric Flux and Gauss’ Law including: Electric flux for a constant electric field, an example of the flux through a closed rectangular box, the electric flux from a point...
