Coulomb’s Law Purpose: The purpose of this lab was to demonstrate that the force between two stationary charges is directly proportional to the product of the charges and inversely to the square of the distance between them. Coulomb’s law tells us that the force between two charges depends (1) linearly on the strength of each charge‚ and (2) inversely on the square of the distance between them. Mathematically we would write this as . Procedures Part1 Begin by removing the right side

World Population Lab : Power of the Pyramids Introduction: The population of the world is slowly increasing. As the population grows the demands of the population grow. People need land to live on‚ wood for furniture ‚etc. For all this‚ people cut down a lot of trees. This is very harmful for the earth’s environment for it reduces the amount of oxygen in comparison to that of carbon dioxide. Therefore‚ all this would lead to global warming. The estimated population of the world today is 6‚873‚811

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous

solutions of each substance were sterilized by passing them through a 0.22 μm (Nupore Filtration Systems‚ UP‚ India) filter. The actively growing cell suspension was treated with elicitors and precursor indiviually on the day of inoculation. The effect of elicitors (ABA‚ SNP‚ SA‚ and MeJA) and precursor (Phenylalnine) on stimulation of anthocyanin in the cell suspension cultures of D. carota was studied at various concentrations viz. 10‚ 50‚ 100‚ 200 μM and phenylalanine viz. 0.5‚ 1 and 5 mM.The samples

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

I.Purpose The purpose of this lab is to show how potential energy and kinetic energy is shown and transferred using a model rollercoaster. This lab also demonstrates the Law of Conservation of Energy. II.Introduction Potential and Kinetic energy have a very big relationship. The Law of Conservation of Energy states that “Energy cannot be destroyed or created‚ but can be transformed or transferred.” This lab will help demonstrate this law and show the conversion between Kinetic and Potential

Title: The effect on temperature on beet cell membranes. Introduction A cell membrane or plasma membrane is very important in protecting cells. A cell membrane is a thin layer that protects the cells. The membrane is filled with lipids and proteins. The cell membrane protects the cell from ions and molecules that enter and exit the cells. I hypothesize that at -5 degrees Celsius‚ the color intensity will be a 1. I hypothesize that at 5 degrees Celsius‚ the color intensity will be a 2

McLean 1 Creating Acetylene Gas Introduction The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel

the piston of a crank and connecting rod assembly Theory The slider crank chain is one of the two basic mechanisms which from the basic for many more complicated motions. (The others are the four Bar Chain‚ Scoth Yoke or Chebyshev linkage of which over 800 forms are known). It transforms linear motion to circular motion or vice versa. A crank is an arm attached at right angles to a rotating shaft by which reciprocating motion is imparted to or received from the shaft. It is used to convert circular
