APPARATUS: The major apparatus used include; Oscilloscope‚ two audio oscillators‚ battery and connectors. THEORY: The oscilloscope is a very widely used instrument because of its versatility. It is a standard piece of equipment used in many types of scientific laboratories. It moves a beam of electrons across

Relative Humidity Lab 1. Yes‚ our relative humidity was different for the two locations because the temperature in the building was lower than the temperature outside. 2. The psychrometer has a "sock" on the bulb of the thermometer. You get the sock wet and twirl the thermometer around for 30 seconds. If the temperature dropped then you spin it again for 15 seconds. Then you subtract the temperature of the psychrometer from the starting temperature and that is the difference. Then you must look

= dM/dx ). In contrast‚ nonuniform bending refers to flexure in the presence of shear forces‚ which means that the bending moment changes as we move along the axis of the beam. As an example of pure bending‚ consider a simple beam AB loaded by two couples M1| having the same magnitude hut acting in opposite directions (Fig. 1a). These loads produce a constant bending moment M = M1 throughout the length of the beam. Note that the shear force V is zero at all cross sections of the beam.

Absolute poverty is a level of poverty defined in terms of the minimal requirements necessary to afford minimal standards of food‚ clothing‚ health care and shelter. For the measure to be absolute‚ the line must be the same in different countries‚ cultures‚ and technological levels. Such an absolute measure should look only at the individual’s power to consume and it should be independent of any changes in income distribution. The intuition behind an absolute measure is that mere survival takes

required a yes response‚ it would be more likely remembered. Method Participants 52 participants enrolled in Cognitive psychology PSYC2300 at the University of Newcastle. Design and stimuli The 3 x2 within participant design experiment consisted of two phases. The first phase was a study phase (60 trials) in which participants were asked to process words (5-7 letters in length) to different depths by answering (yes/ no) to various questions about the words (typeface (upper/lower)‚ phonemics and meaning)

Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise
