What Is Hydrostatic Pressure? Hydrostatic pressure is the pressure that is exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. Hydrostatic pressure increase in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above. What You … Read more

A filter is a circuit that removes or filter-out a specified range of frequency components. In other words, it separates the signal’s spectrum into frequency components that will be passed and frequency components that will be blocked. Filters can be classified in accordance with the general characteristics of the filter’s frequency response. If a filter … Read more

The terms, dominant and recessive describe the inheritance patterns of certain traits. The terms are useful concepts when it comes to predicting the probability of an individual inheriting certain phenotypes, especially genetic disorders.  However, the terms can be confusing when it comes to understanding how a gene specifies a trait. In genetics, dominance can be … Read more

What Is Natural Selection? Natural selection is one of the basic mechanisms of evolution, along with mutation, migration and genetic drift.  Natural selection also referred to as “Survival of the fittest’’ is a process by which a species change over time in response to changes in the environment or competition between organisms, in order for … Read more

In physical chemistry and material science, a mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids. One major characteristic of mixtures is that they can be separated into their components, since each part of the mixture has … Read more

In organic chemistry, hydrocarbons are the simplest class of organic compounds and are composed solely of hydrogen and carbon. Hydrocarbons are generally divided into two classes, depending on the presence of a benzene ring, that is, aromatic compounds and aliphatic compounds also referred to as non-aromatic hydrocarbons.   Aromatic Compounds Aromatic compound can be described … Read more

Solubility product is the concentration of ions of electrolyte, each raised to the power of their coefficients in the balanced chemical equation in a saturated solution. It is applicable only for saturated solutions and is constant for a solution at a given temperature. Ionic Product is the product of concentration of ions of the electrolyte, … Read more

What Is Nuclear Reaction? Nuclear reaction is a process in which two nuclei or nucleus of an atom and a subatomic particle (such as a proton, neutron or high energy electron) from outside the atom, collide to produce one or more nuclides that are different from the nuclides that began the process (parent nuclei). In … Read more

What Is A Monomer? A monomer is a molecule that can be reacted together with other monomer molecules to form a larger polymer chain or three-dimension network in a process referred to as polymerization.   There are two types of monomers, that is, those that react when exposed to radical generating materials (chain growth polymerization) … Read more

Kinematics is the study of motion, without considering the forces which produce that motion. Kinematics of machines deals with the study of relative motion of machine parts. It involves the study of position, displacement, velocity and acceleration of machine parts. What Is A Machine? A machine is a mechanism or collection of mechanisms, formed and … Read more
