Addition of Vectors Objectives: The purpose of this experiment is to show that the magnitude and direction of the resultant of several forces acting on a particle may be determined by drawing the proper vector diagram‚ and that the particle is in equilibrium when the resultant force is zero. Principles: RABx = Ax + Bx RABy = Ay + By R2 = R2X + R2Y R = Rx2+Ry2 Tanθ = RyRx θ = Tan-1 RyRx List of Equipment: 1. Force table 2. Four pulleys 3. Four weights 4. Slotted

Cause and Effect on Acid Rain Introduction Beautifully crafted statues are now worn out or severely damaged‚ aquatic wildlife population are dying off‚ forests have lost the leaves that protect their trees and produce food‚ and the rates of lung diseases in humans are rising around the world. The cause of all of these problems can be linked back to acid rain. Most people don’t understand the concept or science behind acid rain. The common belief is that it’s a natural process‚ but it’s actually

BRONSTED-LOWRY ACIDS AND BASES 1. The Bronsted-Lowry definition There are many definitions of acids and bases in existence‚ but the most useful one is the Bronsted-Lowry definition: An acid is a substance which can behave as a proton (re presented as a hydrogen ion‚ H+) donor. Any substance which contains hydrogen bonded to a more electronegative element can thus behave as an acid: HCl == H+ + Cl- H2SO4 == H+ + HSO4- A base is a substance which can behave as a proton acceptor. Any

Acid rain is a rain or any other form of precipitation that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants‚ aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide‚ which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive results. Nitrogen

EMISSIONS FROM ADIPIC ACID AND NITRIC ACID PRODUCTION A C K N O WL E D G E M E N T S This paper was written by Heike Mainhardt (ICF Incorporated) and reviewed by Dina Kruger (USEPA). ABSTRACT Nitrous oxide (N2O) is generated as a by-product during the production of adipic acid and nitric acid. The main use for adipic acid is as a component of nylon-6/6; thus production trends are closely correlated with nylon consumption trends. Worldwide‚ there are very few adipic acid plants. The U.S. is

Folic Acid is a B vitamin‚ specifically B9. It is an essential nutrient required by the body to create healthy new cells. While we hear about it mostly in regards to pregnancy‚ it is important to understand that the need for folic acid goes even beyond this. Folic acid is essential for the body to create red blood cells which in turn prevents anemia. It is also plays an important role in the metabolism of homocysteine‚ an amino acid. The recommended dietary allowance (RDA) for all men and women
