Determining the concentration of red dye #40 in an unknown solution Introduction: White light is composed of many different wavelengths of light combined together. A spectrophotometer is an instrument that shines a single wavelength of light of a known intensity into a solution and then measures the intensity of the light exiting the solution. If a solution contains

Dirt Bikes USA Case Study Chapter 1Management Overview of Dirt Bikes Introduction of Dirt Bikes Dirt Bikes USA‚ a small company headquartered in Carbondalewas founded in 1991 by Car Schmidt and Steven McFadden‚ two young but experienced bikers with engineering backgrounds who saw that dirt bikes were becoming very popular in the Unites States as both sporting and racing motorcycles. In the early time‚ they developed frames for dirt bikes that were more suited to off-road handling and used it

Bill Bryson‚ Notes from a Small Island‚ Black Swan‚ 1995 In the morning I awoke to find rain falling over the hills in great blown sheets. I breakfasted‚ settled the bill and spent a protracted period struggling into waterproofs in the front hallway. It’s a funny thing. I dress myself most days without incident‚ but give me a pair of waterproof trousers to put on and it’s as if I’ve never stood unaided. I spent twenty minutes crashing into walls and furniture‚ falling into pot plants and‚ in one

A theodolite is a survey testing instrument used for measuring horizontal and vertical angles. A basic theodolite usually consists of a small sized telescope linked with mechanisms to measure horizontal and vertical angles. It has several moving parts and is quite heavy. The theodolite telescope is fixed within perpendicular axes- the vertical axis and the horizontal‚ or trunion‚ axis. The instrument is fixed on a base that can be rotated on a tripod by a leveling system. The angle to the desired

that by adding our base Sodium Hydroxide (0.5m NaOH) to the unknown substance F‚ it will not react and be labeled a buffer. We chose this as our buffer because it is clearer than the other unknown substances. Methods In this experiment we used a Vernier computer interface to calculate the pH change of each substance we were given to see which one it effected the most and least. In a 250-mL beaker we filled it up with about 100-mL of distilled water to keep the pH electrode from drying out. Before

Title Soda Ash: Great for the economy but detrimental to the body; So why is it involved in everyday life? Abstract Sodium carbonate‚ Na₂CO₃‚ commonly known as soda ash is used in the manufacturing of many economically important products such as the manufacturing of glass‚ chemicals‚ paper and detergents. Since sodium carbonate has a strong base‚ it is commonly used to neutralize acidic effects. Soda ash has a high pH in concentrated solutions and can irritate the eyes and skin as well

ABSTRACT: The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment‚ one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2‚ which is consistent with the accepted value of 9.8m/s^2. In the

30 is considered obese. Measurements and comparisons of waist and hip circumference can also provide some information regarding risk factors associated with weight. The higher the ratio‚ the greater the chance for weight-associated complications. Calipers can be used to measure skin-fold thickness to determine whether tissue is muscle (lean) or adipose tissue (fat). Much concern has been generated about the increasing incidence of obesity among Americans. Some studies have noted an increase from
