Simple Harmonic Motion By Panun Bali Aim: The aim of this experiment was to determine the spring constant “k” of a spring using Hooke’s Law and Simple Harmonic Motion. Theory: Part 1: We know from the theory that the Time Period “T” for any spring that undergoes simple harmonic motion: T = 2π * √ (m/k) Where “T” is the Time Period of the spring; “m” is the mass attached to the spring and “k” is the spring constant of the spring used. After mathematically manipulating the equation

Using a spirometer to investigate human lung function The purpose of this activity is: • to show how a spirometer can be used to find the vital capacity of lungs and to calculate important subdivisions of this capacity. • to show how to interpret the trace resulting from use of a spirometer • to consider how to use a spirometer to estimate metabolic rate. Procedure SAFETY: Do not use a spirometer unless supervised by a teacher. If you are using the spirometer and you experience

Riley Jefferson Block 7/8 October 8th 2012 Electrostatic Gedanken Lab Group Gamma Objective: The objective of this lab is to determine the charge on a pith ball. Hypothesis: I fully believe that the charge of the pith ball will be positive. The formula I will use to prove this is Coulomb’s Law‚ (Fe=(k*q1*q2) / r²). ‘Fe’ is equal to the electrostatic force between the spheres‚ measured in Newton’s. It is also a vector quantity‚ and it’s in absolute value. Secondly‚ ‘k’ is equal to Coulomb’s

Ball mill is the key mining equipment of material to be crushed‚ and then to smash. It is widely used in cement‚ silicate product‚ new building materials‚ refractory materials‚ fertilizer‚ black and non-ferrous metal ore and glass ceramic production industry‚ a variety of ores and other grind-able materials can be dry or wet grinding. Tube ball Mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes‚ paints‚ pyrotechnics‚ and ceramics. SBM

Nowadays everybody is talking about the internet‚ a century creation‚ which has converted the whole world into a single home. The use of internet has turned our lives to be much easier and comfortable. It is found that in 1990s the adolescents used the internet primarily for entertainment but at present they use it for interpersonal communication. Opportunities for youths to form‚ maintain and develop relationships on the internet have multiplied in the past few years. Along with the increase in

Simple Harmonic Motion Lab Report In this lab‚ I will study the principles of simple harmonic motion using an oscillating pendulum. If I were to design an experiment that would help me study the properties of an oscillating pendulum and investigate what causes a pendulum to swing faster or slower‚ I would prepare several masses (e.g. 20g‚ 50g‚ 100g‚ 200g‚ etc.) that can be attached to a string‚ several strings of varying lengths from 0.1m to 1.0m that are strong enough to support the weight of the

primarily about Newton’s second law of motion. Newton’s second law of motion states that a net force is required for a body to have acceleration. If a net force is applied on an object‚ then the object will accelerate with respect to the direction of the said force. The body’s acceleration is directly proportional to the net force and inversely proportional to its mass. The experiment conducted was used to verify the relationships specified in Newton’s second law of motion. There were 3 trials‚ and these

Inspection on the equipment and its subsidiary facilities. (1) The ball mill inspection: a. Check the loose screws‚ the loose‚ broken screws on the lining plate in particular‚ which may lead to leakage; b. Check the wear pattern of the sand return spoon head; c. Pay attention to the coarse running and ball vomiting of the ball mill discharge. (2) The oil feeding system inspection: a. Check the oil pressure constantly to keep it within the range of 1.5~20kg/cm2;b. Check the oil mass and temperature

October 9‚ 2013 Using Their Resources I am not a poor inner city kid. I am a teenage white girl who comes from a middle class white background. So life is easier for me. But that doesn’t mean that the succession is impossible for those kids from the inner city. It doesn’t mean that there are no opportunities for them. I believe that everyone in this country has a chance to succeed. Even a poor inner city kid in Kansas City. It takes brains. It takes hard work. It takes a little luck‚ and
