Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &

Synopsis The objective of this CDIO experiment was to determine the mechanical property of polymeric materials which was the tensile properties .The testing standard to adopt for the tensile testing was ASTM D638. Four different types of polymers were placed into the tensile testing machine. The different specimens

Lab 20: Flame Tests Purpose/Objective: The ground state is the normal electron configuration of atoms or ions in an element. When atoms or ions in ground state are heated to a higher temperature‚ some electrons absorb enough energy to move them to higher energy levels. This is known as the excited state. However‚ the excited configuration is unstable‚ and the electrons must return back to their positions in the lower energy level. As they return‚ the energy that was previously absorbed is now emitted

The Charge/Mass (e/m) Ratio of the Electron PHYS 0212: Introduction to Laboratory Physics Fall 2012 Abstract The experiment conducted demonstrated correlation between the charge and mass of an electron and the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found

China marker‚ I numbered test tubes 1-5 for identification purposes. Using a pipet I added 1 milliliter of each solution to it’s designated test tube. Next‚ I added 5 drops of the Biuret reagent to each test tube and agitated the mixture by shaking the tubes from side to side. After waiting 2 minutes I recorded the color of each mixture. I used the color reaction after adding the reagent to determine the presence of proteins in each substance (Mbuthia‚ 2012). Results Test solutions that contained

Part 2: Safe work with large inductances 1. One of the main hazards of using inductances is electrical energy stored in the magnetic field. If a circuit containing an inductance is interrupted then the stored energy can release through air (forming an arc). This can destroy a switch contact‚ burn fingers‚ create other damage. In the circuit of Figure 1‚ show how to mitigate the risk (pay attention to polarity!). We give the elements in this circuit some simple values for the purpose of

inherited independently of each other. Apply the rules of probability to infer genotypes from test crosses A test cross is used to determine the genotype of an individual with a dominant trait. Because the trait is dominant‚ an individual with the trait could be homozygous or heterozygous for the trait. (This cannot always be determined by simply looking at the phenotype of the individual.) In a test cross‚ an individual with the dominant phenotype is crossed with a fully recessive individual
