Part one: The Lab You will be helping Galileo perform the experiment to determine if objects with different mass fall at the same‚ or different‚ rates in the air and in a vacuum. Before you conduct your experiment‚ you need to form a hypothesis. A hypothesis is a prediction of what you think will happen in the experiment. The hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. Record your hypothesis here:

of refraction of a medium is defined as the ratio of the speed of light in vacuum to the speed of light in the medium. [pic] By definition‚ n = 1 in vacuum. In all materials n > 1. The frequency of light does not change as it goes from one a medium of one index of refraction to another. This means that the wavelength changes with the speed. [pic] Thus‚ the wavelength is smaller in a medium than in vacuum. From the definition of the index of refraction‚ we can rewrite the relationship

steam. If this condensation takes place in a sealed container‚ it creates a partial vacuum‚ or a pressure much lower than that of the surrounding atmosphere. Liquids and gases tend to flow from regions of higher pressure to regions of lower pressure‚ so when a vessel containing a partial vacuum is opened‚ the vacuum exerts a sucking action on whatever is on the other side of the opening. Thus‚ the partial vacuum and the surrounding atmosphere act together to perform work. (World Book‚ 881; Macaulay

the 20th century‚ vacuum devices were introduced‚ and later several types of pills were developed that could serve as contraception‚ or cause a spontaneous miscarriage (historyof.com). Today‚ there are a few different medical ways an abortion can be performed. These are relatively safe surgeries‚ considering of course the actual practice. One of the main surgical abortion procedures is known as aspiration. The procedure‚ also known as “suction aspiration‚ suction curettage or vacuum

Applications of Differential Forms Maxwell Faraday and Maxwell Ampere Equations R. M. Kiehn (in preparation - last update 10/31/97) Physics Department‚ University of Houston‚ Houston‚ Texas Abstract: The topological universality of the Maxwell Faraday and Maxwell Ampere equations is an artifact of C2 differential forms on a domain of dimension n * 4. Starting with a 1-form of (electromagnetic) Action‚ the Maxwell Faraday equations become a consequence of the Poincare lemma. Starting from an

Abstract:The Wittig Reaction is a nucleophilic addition in which an alkene is formed as a product. Both the E and Z isomers of the alkene result. Substituents on the aromatic aldehyde affect the E/Z ratio of products that form. In this experiment‚ a nitro group was used as the substituent in the ortho‚ meta and para positions‚ with benzaldehyde as the control. Each of the four aldehydes reacted with (carbethoxymethylene) triphenylphosphorane to produce ethyl cinnamate‚ ethyl-3-(2-nitrophenyl)acrylate

Semiconductors are either solid or liquid material‚ able to conduct electricity at room temperature more readily than an insulator‚ but less easily than a metal. Electrical conductivity‚ which is the ability to conduct electrical current under the application of a voltage‚ has one of the widest ranges of values of any physical property of matter. Such metals as copper‚ silver‚ and aluminum are excellent conductors‚ but such insulators as diamond and glass are very poor conductors. At low temperatures

Introduction People encounter esters everyday in both natural and synthesized forms. Esters are present in a variety of common compounds‚ from fragrances to animal fat (McMurry‚ 2008). Although these esters can undergo many different important reactions‚ this lab is particularly interested in the hydrolysis of esters into carboxylic
