The Pentagon is a polygonal figure that has five sides. It is the second simplest polygonal figure after the square. The Pentagon has a long history in geometry and has been used in art and architecture for centuries. In mathematics, the Pentagon is used as an example of a regular polygon with an odd number … Read more
It takes a lot of time to create a scientific project, even an elementary one. Lab reports require experimenting and evaluation; hence these projects can be considered scientific too. Each student knows that creating lab reports is a very challenging process. And being assigned a lab report on a complicated discipline like chemistry often becomes … Read more
When the word ‘relative’ is used, it means that something is being viewed in relation to or in proportion to another. An event’s frequency can be measured by measuring how often it occurs. On the other hand, relative frequency measures how often a particular event occurs relative to its total occurrences. Let’s look at some … Read more
Roots of a Polynomial A root or zero of a function is a number that, when plugged in for the variable, makes the function equal to zero. Thus, the roots of a polynomial P(x) are values of x such that P(x) = 0. The Rational Zeros Theorem The Rational Zeros Theorem states: IfP(x)is a polynomial with integer coefficients and ifis … Read more
Bronze Age, third phase in the development of material culture among the ancient peoples of Europe, Asia, and the Middle East, following the Paleolithic and Neolithic periods (Old Stone Age and New Stone Age, respectively). The term also denotes the first period in which metal was used. The date at which the age began varied with regions; in Greece and China, for instance, the Bronze Age began before 3000 BCE, whereas in Britain it … Read more
The act of dislocating an object when a force acts upon it is said to produce work. Work involves a force through which an object can be displaced. When the work is completed, the thing will gain energy. The energy acquired by an object on which work is done is known as its mechanical energy. … Read more
Biomass pyramids are a visual representation of the biomass present in a unit of the territory of different trophic levels. Additionally, it displays a link between biomass and trophic level, estimating the biomass available in each ecological degree at a given moment. There are two primary kinds of biomass pyramid – the altered biomass pyramid and the … Read more
There is no doubt that you are very familiar with the term average acceleration, especially in relation to cars. We say something is accelerating when it changes velocity. Acceleration is the rate at which velocity changes over time. In layman’s terms, we use acceleration to describe a state of increasing speed. As with velocity, there … Read more
The normal force, also known as the normal reaction force, is a contact force. A normal force cannot be exerted on two surfaces that are not connected to one another. Consider a table and a container; when they are not in contact, they cannot exert normal force on one another. When two objects come into … Read more
