Abstract This was an investigation into the effects of different wavelengths of light on methylene blue and carmine red on the absorbance value on a spectrophotometer. A spectrophotometer is used to measure light intensity by emitting a single light source through a cuvette of coloured …

To find the moment of inertia, you find the area under, and also between the curve(s). An application in which integration is key to reaching the target value is a PAID Controller. The purpose of a PAID Controller is to determine the error between what …

Robert Bruce August 10, 2012 Leadership The Accidental Leader Albert Einstein was a world-renowned German-born theoretical physicist. Best known for his theory of relativity and famous equation of E = mc2 the expression of mass-energy equivalence. In 1921 he received the Nobel Prize in Physics …

The Great Muslim Scientists of All Time. Here is a little intro about them and their work to the world of science. All the scientists are before 14th century .. ,When you the Europe was called a Dark continent ,Muslims Scientists Were ruling in all …

The hypothesis about the heat death of the universe Our knowledge of the universe is still negligible, and we can not confidently assert that the universe is not under the influence of external forces, or may be considered as a thermodynamic system. However, it is …

In this report, I will be writing about the experiment I will conduct on copper wire of different lengths. The dependent variable I will be measuring is the resistance of the Copper wire. To do this experiment, one needs to obtain measurements with a high …

Mrs. Morris English Comp 106 27 March 2013 Washing Dishes A nice meal was just enjoyed by the family. Everyone is sitting around the table with full stomachs not wanting to get up, but it has to be done. All the essential items are already …

Questions 1. Plot a graph of: Turbine velocity versus flow rate.  Turbine velocity versus output torque. Turbine velocity versus hydraulic power. Turbine velocity versus mechanical power. Turbine velocity versus efficiency. 2. Give your comment(s) from the graph obtained. Based on the graph Turbine velocity versus …

Nuclear energy is a type of energy which is released by a reaction called as nuclear reaction. There are two main types of nuclear reactions, one is called fission and the other one is fusion: In Fission reaction it releases a nuclear energy when a …

Abstract: In this experiment we were provided a cereal box spectrometer to observe the emission lines of noble gases and hydrogen. Based on the scale readings on the spectrometer and the Balmer-Rydberg formula, their wavelengths and percent error were able to be extrapolated. Based on …

Molecules of Life Computer Assignment A) What characteristics are typical of molecules that are gases at room temperature? Molecules that are gases at room temperature tend to be smaller in size. This causes it to have a small molecular masses and has a relatively weak …

Conflict theory is based on the idea that the main causes of crime and deviance are the economic and social differences among members of a society, prompting the have-nots to act out, if not to rob the haves. According to this theory, criminal law and …

BALANCING OF ROTATING MACHINES The first thing to be explored to control vibrations is to try to alter the source so that it produces less vibration. This method may not always be feasible. Some examples of the sources of vibration that cannot be altered are …

Pin hole camera was invented by a Muslim scientist ibn-al-haitham. An Egyptian polymath (born in Iraq) whose research in geometry and optics was influential into the 17th century; established experiments as the norm of proof in physics (died in 1040). Another inventor is the tenth …
