Understanding Problems on Ages (Beginner-Friendly Guide)
Problems on ages may look tricky at first, but once you understand the pattern, they become very easy. The key idea is that age changes uniformly with time. That means every person’s age increases or decreases by the same number of years when we move forward or backward in time. Core...
Electric Currents and Basic Circuits
Electric current (I): Electric current is the flow of electric charge through a conductor over a period of time. It is defined as the rate at which charge flows past a given point in a circuit. Mathematically, it is expressed as: i = qt (C/s) Where; q = charge (C) t = time (s) The unit of electric current is Coulomb...
Complete Guide to Electrostatics for Science Students
Electrostatics as the name suggest - Electro and Statics is the science that studies of electricity at rest. The fundamental concept in electrostatics is electrical charge. As we know, atoms are electrically neutral, because the total charge is balanced as the charges of protons equates that of the electrons. An addition or removal...
How to solve vectors
Introduction Physical quantities are categorized into two primary types: scalar quantities and vector quantities. Scalar Quantities: Scalar quantities are those quantity with just magnitude and does not specify its direction in space. Examples of scalars include length, mass, time, area, or volume. The description of a scalar quantity is complete once the...
Geometric Analysis I (Lines Planes Triangles and Polygons)
Geometry deals with measures and properties of points, lines, planes, surfaces and solid. We would go into detail the following as well as their respective properties: Lines Angles Polygons Triangles Lines A line in geometry is a straight one-dimensional figure that has no thickness and extends infinitely in both directions. It is typically represented with two arrowheads...
