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

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

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

conducted on 13th August 2008 in Machines Dynamics Laboratory. The experiment was conducted in groups of four‚ and was supervised by lecturer Mr. Mohd Azahari Johan. Conducting this experiment is for fulfilling the requirements of Applied Mechanics Lab (MEC 424). A pendulum is defined as body so suspended from a fixed point as to swing freely to and from by the alternate action of gravity and momentum. It is used to regulate the movements of clockwork and other machinery. Therefore‚ a compound

Lab Report – Strong Example Problem/Question Does using a base coat before painting nails prevent chipping? Background Information When painting nails‚ some manicurists use a base coat before applying the polish. The purpose of a base coat is to help the polish stick to your nails more easily. Base coats also help to protect your natural nail from the staining effects of colored polishes. Ridge-filling base coats fill in the grooves and cracks in the nail to create a smoother appearance
