Theory What is rust? Rust is the common name of a compound‚ iron oxide. Iron oxide‚ the chemical Fe2O3‚ is common because iron combines very readily with oxygen -- so readily‚ in fact‚ that pure iron is only rarely found in nature. Iron (or steel) rusting is an example of corrosion -- an electrochemical process involving an anode (a piece of metal that readily gives up electrons)‚ an electrolyte (a liquid that helps electrons move) and a cathode (a piece of metal that readily accepts electrons)

of test specimens with those predicted by the Euler equation. Apparatus: 1. SM 105 strut apparatus (Issuing Voucher: 0203141 & Inventory Ledger: CN/s/01/10)‚ 2. Aluminum bar specimen (20 x 3 x 600 mm approximate)‚ 3. Measuring ruler‚ 4. Venier caliper. Theory: The factors affecting the column’s load – carrying capacity are the connection between the slenderness of the column and its tendency to buckle‚ the influence of the ‘fixity’ of the ends of the column‚ and the shape of its section on that

CHAPTER I INTRODUCTION Background of the Study The use of plants for remedies has long been in existence and is among the most attractive sources for developing drugs (Bukantis et al.‚ 1980). Any part of plant can be considered as herbs including leaves roots‚ flower‚ seeds‚ resins‚ leaf sheath‚ bark‚ inner bark (cambium)‚ berries and sometimes the pericarp or other portion (Holetz et al.‚ 2002). Most primates depend heavily on the leaves‚ fruits‚ and flowers of tropical plants to meet their nutritional

JOSEPH MERRICK‚ dubbed "The Elephant Man"‚ is one of the most famous patients in history‚ not just on account of his frightful appearance while he was alive‚ but also because of the division of opinion amongst the medical establishment after his death over just what disease he had suffered from. Mr. Joseph Merrick‚ The Elephant Man‚ was born on August 5th 1862 - a year after the start of American Civil War - in Leicestershire‚ Great Britain. His mother was slightly crippled but his brother was normal

First of all‚ forensic science is the application of math and science in criminal investigations in order to prove someone’s innocence or guilt in the court of law.Forensic science includes many different fields that need the application of math‚ such as: Forensic Anthropology‚ Forensic Chemistry and Toxicology‚ Forensic Mathematics‚ Forensic Reconstruction‚ Forensic Technology‚ and Latent Print Identification. Forensic scientists use measurements‚ proportions‚ trigonometry‚ and probabilities in

The refractive index Aim: The aim of this experiment is to find the refractive index of a glass prism. In this experiment‚ the independent variable is the angle of incidence‚ and the dependent variable is the angle of refraction. Theory: Snell’s law relates the angle of incidence and refraction to the ratio of the velocity of the wave in the different media. The formula for Snell’s law is the following: Sin isinr = v1v2 = n Where i is the angle of incidence‚ r is the angle of refraction

Physics coursework The Experiment Our experiment is to investigate the time it takes for an object to free fall and from our results work out a value for gravity. The experiment will include us dropping a golf ball from a different height and measuring the time it takes to pass through a light gate. Our hypothesis for the experiment is that as the drop height of the golf ball is increased the velocity of the ball will increase‚ this is because it has more time to accelerate. We hope to
