A. ENG237-02: Transients in RC and RL Circuits 0. Introduction The objective of this experiment is to study the DC transient behaviors of RC and RL circuits. This experiment has divided into 6 parts: 1. Charging curve from measured data ( R = 10M Ω and C = 4 mF ) 2. Draw the charging curve by the graphical method 3. Discharging curve from measured data ( R = 5M Ω and C = 4 mF ) 4. Draw the discharging curve by the graphical method 5. Display of the charging and discharging

Experiment Title: Torsion Vibration. Introduction : Torsion is the twisting of a metallic rod shaped object‚ when a torque is applied on two sides’ perpendicular to the radius of a uniform cross-sectional bar. Objective : Determining the natural frequency of a system undergoing tortional vibration. Theory : Using Newton’s second law of tortional system. ( [pic] …………………. ( Equation 1 ) where Io = mass moment of inertia of the disk Hence‚ [pic] ……..……

Boys’ Code of Conduct In the article “How Boys Become Men”‚ written by John Katz‚ he analyzes situations he experienced while growing up. Katz believes that boys become men by not showing fear or feelings and not ratting on others. As in the novel‚ The Other Wes Moore‚ both Weses are forced to become men at an early age. They experience events that push them to make decisions that make them grow and think like men do. Katz details the maturation process for boys‚ as the book‚ The Other Wes Moore

Research Question How will the addition of different pH buffers to amylase affect the rate of starch digestion measured using starch and iodine? Introduction Amylase is an enzyme found in human saliva and pancreas. It is the digestive enzyme that is needed to breakdown starch molecules. Amylase must be kept at certain conditions to function at its optimum level. This experiment will explore the effect of pH (1‚ 4‚ 7‚ 10‚ and 14) on the function of amylase by using starch and iodine. Usually

Determination of presence of protein in a variety of food substances by the use of Biuret Reagent Biol. 1040 Section 1005 Introduction The human body consumes carbohydrates‚ lipids‚ and proteins each day by eating a variety of foods. These foods are required for energy and human growth. Proteins are a diverse group of macromolecules with many different functions (Mbuthia‚ 2012). Many are structural components of bone‚ muscle‚ hair‚ tissue‚ etc. Others are enzymes that speed up cellular

Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 | Instructor: Mr. Nailer | I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT)‚ its mass (m)‚ and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine
