Quadratic equations is any equation of the form ax2+bx+c=0 where a is not zero. In other words, quadratic equation is a quadratic expression that is equated to a zero as a value. solving quadratic equations methods of solving quadratic equations includes: solving Quadratic Equations by factorization consider the quadratic equation: x2+3x-54 = 0. we find…

The potential difference between to points A and B (Vab) of a conductor is defined as the work done in moving unit charge from point B to A of the conductor. The figure below illustrates the movement of charge in a conductor under the influence of a potential difference. One volt is equal to one…

Georg Simon Ohm In 1825, Georg Ohm tested wires of varying length, diameter, and material to complete a circuit. He found that his data for current, voltage and resistance could be modeled through a special equation, which we know today as Ohm’s Law. The Ohm’s law summaries about the relation that exists between the voltage…

Basic terms in education research represents the vocabulary used in the topic. In educational research, there are several key terms and concepts that are commonly used. Here are some of the basic ones: Population It refers to the group of individual, events/ objects having common observable characteristics SAMPLE IN EDUCATION RESEARCH SAMPLING VARIABLE DATA 2.…

Rationalizing a denominator means eliminating any radicals (like square roots) from the denominator of a fraction. To do this, multiply both the numerator and denominator by a value. This value should make the denominator a perfect square or a rational number. Here’s an example: Suppose you have the fraction: To rationalize the denominator, you multiply…

Quadratic expressions are algebraic expressions of the form ax2+bx+c where a, b, and c are constants and a!=0. Constants means real numbers. if a=0, the expression would be linear rather than quadratic. When a graph of a quadratic expression is plotted against x ,is a parabola is formed. If a is greater than 0, the…

In electrostatics, charging bodies means adding or removing electrons from atoms of objects. This results in an imbalance of electric charge. If electrons are added, the object becomes negatively charged; if electrons are removed, it becomes positively charged. This creates an electric field around the charged object, which can exert forces on other charged bodies.…
