1. INTRODUCTION In computing‚ a mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically‚ a mouse consists of an object held under one of the user ’s hands‚ with one or more buttons. The mouse sometimes features other elements‚ such as "wheels"‚ which allow the user to perform various system-dependent operations‚ or extra buttons or features that can add more control or dimensional input. The mouse ’s motion typically translates

there actually is some precipitate at the bottom. This showed that the solution was white and sparingly soluble. Looking at Table 6‚ SO4 is the only anion that produces a white‚ sparingly soluble color. The anion SO4 can also be identified from the infrared spectra‚ which matched perfectly with the spectra given from SO4. There were peaks from 1150-1060 and 615-605. These were the ways to finalize the identification of SO4. The final solution to my inorganic solid was Cobalt (II) Sulfate – CoSO4

Experiment 13: Synthesis of 1- Bromobutane An SN2 Reaction Theory: One of the methods of preparing alkyl halides is via the nucleophilic substitution reactions of alcohols. Alcohols are inexpensive materials and easy to maintain. However‚ they are a poor leaving group the OH group is a problem in nucleophilic substitution‚ this problem is fixed by converting the alcohol into H2O. Objective: The objective of this lab is to observe the synthesis of 1-bromobutane in an SN2 reaction‚ to see how

FREE SPACE OPTICS Free space optics or FSO‚ free space photonics or optical wireless‚ refers to the transmission of modulated visible or infrared beams through the atmosphere to obtain optical communication. FSO systems can function over distances of several kilometers. FSO is a line-of-sight technology‚ which enables optical transmission up to 2.5 Gbps of data‚ voice and video communications

When solid objects are heated‚ they emit radiation. At normal temperature‚ we are not aware of this radiation because the intensity is low. At higher temperatures‚ there is sufficient infrared radiation that we can feel the "heat" if we are close to them. At even higher temperature‚ the objects actually glow‚ like the heating element of toaster or red-hot electric stove burner. Since they are radiating energy‚ there must be a rate at which they are radiating. They may radiate 10 Joules per second

temperature. The bigger the temperature difference‚ the faster the heat transfer. Heat moves by three different processes: Conduction - mainly in solids Convection - mainly in liquids and gases Radiation - any state of matter can absorb/emit infrared radiation. Conduction Vibrations in matter are passed on to transfer heat energy. This is called conduction. Insulator - a material that stops energy being transferred. Solids are good conductors because the particles are closer together and

and terminating. Eye contact may cause serious injury. Lasers can be harmful‚ but injuries from lasers are easily preventable. Always assume that every fiber is active. Nearly all communication systems use infrared light to communicate. An infrared detection card must be used to detect any infrared light. The biggest area of concern is inspecting connectors with a microscope. It is easy to forget to deactivate a fiber before viewing it. Remember‚ you will not see or feel the danger.
