We already know what are elements in chemistry. In this article, we will learn about the most abundant element on earth and its atmosphere. Some elements are found in abundance whereas some elements are almost rare on the Earth. Did you know that there are a total of 118 elements? (read What is an element …
In this article, we will learn about what elements are along with examples. We will define chemical elements, learn about how many elements are there, and will discuss isotopes and allotropes during the course of our article.

ADVANTAGES
The generation of A.C. is cheaper than that of D.C.
A.C. machines are simple , robust and do mot require much attention for their repairs and maintainance during their use.
Wide range of voltages are obtained by the use of transformer.
In this article, we would learn about charge density and its formulas and would also solve some problems related to this concept. We encounter electric charge density while calculating electric field from various continuous charge distributions like linear, surface and volume. We also need the concept of charge density while studying current electricity. What is Charge Density? …

Introduction about physics and studying the subject This article is mainly about use of units in physics. But before going further let us first discuss about how to avoid problems that students face while studying physics. When you study physics you must have appropriate skills or you would have to struggle a lot while studying …
You must have ride Roller coaster or ferris wheel in the amusement park. Its up and down and moving in the circle must have thrilled and fascinated you Today I would like to give a brief details about those machine and how you feel different in those rides.
