What is an ionic bond? Typically an ionic bond occurs between one metal and one non-metal ion. One atom borrows one or more electrons from another atom. An ionic bond is a type of chemical bond that occurs when one atom loses an electron to …
Daniel Bernoulli (Groningen, 8 February 1700 – Basel, 8 March 1782) was aDutch-Swiss mathematician and was one of the many prominent mathematicians in theBernoulli family. He is particularly remembered for his applications of mathematics to mechanics, especially fluid mechanics, and for his pioneering work in probability andstatistics. Bernoulli’s work is still studied …
There are many reasons that we need bridges in every day of our life, from sufficient means to pass over a roadway, waterway, railway, or other structure. You don’t even think about them because it takes no effort to get over them and they are …
BEAM BENDING The bending of beams is one of the most important types of stress in engineering. Bending is more likely to be a critical stress than other types of stress – like tension, compression etc. In this laboratory, we will be determining the Modulus …
I chose Stephen Hawking to write about for my case study because I have always found him extremely interesting. As a fellow atheist he has come pretty outstanding scientific theories on how our universe came about, none of which are attributed to some fictitious being. …
Aim To determine the relationship between the length of eureka wire, and resistivity of the wire. Hypothesis: As the length of the wire increases, the resistance of the wire will increase. Background: Some materials have consistent resistance at the same temperature regardless of how much …
Doppler effect The Doppler effect, named after Christian Doppler, is the change in frequency and wavelength of a wave as perceived by an observer moving relative to the source of the waves. For waves that propagate in a wave medium, such as sound waves, the …
Nuclear power stations work in fossil fuel-burning stations, except that a “chain reaction” inside a nuclear reactor makes the heat instead.The reactor uses Uranium rods as fuel, and the heat is generated by nuclear fission: neutrons smash into the nucleus of the uranium atoms, which …
Cyrus Newton Ray was a man who found his sole purpose of fulfillment by finding evidences of artifacts from the past. His original studies were focused on the medical field: osteopathy, which he received a degree for in June 2, 1909. It is bizarre to …
This equipment is a benchtop unit designed to introduce students to pressure, pressure scales and common devices available to measure pressure. The equipment comprises a Dead-weight Pressure Calibrator to generate a number of predetermined pressures, connected to a Bourdon gauge and electronic pressure sensor to …
DEFINITION OF HEAT TRANSFER| Heat transfer is energy in transit due to temperature difference . Whenever there exists a temperature difference in a medium or between media, heat transfer must occur. The basic requirement for heat transfer is the presence of temperature difference . There …
ABSTRACT On the past two weeks, I have done an experiment on hydrostatics, or is also known as fluid statics (fluid at rest) within the fluid mechanics field of study. This condition explains that in a stable condition, the fluid is at rest. The use …

Introduction Living organisms have been classified by humans according to several different characteristics, one of them being the manner in which they obtain nutritive organic molecules (1), in other words, their food. Plants are denominated as autotrophs, organisms that can produce their own food from …
Magnitude
In physics, magnitude is described in simple words as 'distance or quantity'. It shows the direction or size that is absolute or relative in which an object moves in the sense of motion. It is used to describe the size or extent of something. Generally, in physics, magnitude relates to distance or quantity.
Equilibrium
equilibrium, in physics, the condition of a system when neither its state of motion nor its internal energy state tends to change with time.
