Sum of cubes: Natural numbers, formulas, examples, and more
If I write this mathematically then, let s be the sum of 1 cube plus two cubes plus three cubes plus four cubes up to n cube. Now there are two important things that we already know. Now, the first thing is the sum of…
Branches of science: All you need to know about branches of science
Science is the systematic study of the mystery of nature. Moreover, science develops from definite steps. These definite steps are scientific methods. First, we need to know what observation is. Because when we want to know anything about living things or elements, we need to…
17th-century scientists and their major contributions
During the 17th century, major changes occurred in the areas of philosophy and science. Scientific studies and scientists were not well-known before the beginning of the 1600s. Isaac Newton was a 17th-century physicist. People used to call the key thinkers and peers like him natural…
Air: Is it a Compound, Element, or Mixture?
Air is a mixture of several gases, not a composition. Nitrogen, oxygen, the life-sustaining ingredient for animals and humans, carbon dioxide, water vapor, and trace amounts of other elements make up the atmosphere (argon, neon, etc.). Ozone, helium, and hydrogen are also found in higher…
Turgidity: Definition, Significance, Types, Examples & Difference With Rigidity
Turgidity is required for plant cells to stand in one place for long periods. Turgid describes a cell that has been fully bolstered. It’s a cellular phase in which a plant cell is in a state of tension after drowning in water. Thus, turgidity is…
Circle Of Illumination: Definition, Motions, Terms & Revolution
We might have wondered how exactly night comes after a day or how the earth decides how many hours will be there in each. This is what the circle of illumination does- the division of the hours of a day into day and night. What…
Areolar Tissue: Definition, Functions, Structure & Location
Cells are the structural and functional units that cover the entire human body. Instead of the cells having an individual structure, they are grouped into clusters. We call these clusters ‘tissues’. Biologically, tissues are groups of cells that have a collective function. The cells might…
Combination Reaction: Definition, Examples & Exothermic In Nature
Substances combine chemically to create new substances. The new substances have properties completely different from the initial substances. The initial substances that undergo the reaction are called reactants. The reaction between the reactants creates the substances called the products. In other words, a chemical reaction…
Superposition Theorem: Definition, Explanations, Conditions & How To Apply
The superposition theorem is based on the superposition principle which is used to analyze networks in electrical circuits. It is essential because it operates in the process of converting any circuit to either its Norton correspondent or its Thevenin equivalent. This theorem is functional for…
Ammonia – a Lewis Acid or a Lewis Base?
One of the fascinating substances to learn about is ammonia or NH3. It has a pleasant odor and emits a colorless, fire-resistant gas. One nitrogen atom and three hydrogen atoms make up this compound. Ammonia is a polar molecule because its electron sharing is asymmetric….
