Kara Vo Florence A1 10/25/17 Weighty Matter Lab 2.3 Problem: What is the relationship an object’s mass and an object’s weight? Design: In this lab‚ we are finding the relationship between an object’s mass and an object’s weight by creating a graph that represents the gravitational field strength. On the graph‚ the mass of the object (m) was located on the x-axis because it’s the independent variable. The weight of the object (Fg) is on the y-axis since it’s dependent on the mass of the object

Research on Conduction‚ Convention‚ and Radiation Conduction is the exchange of warmth between substances that are in direct contact with one another. The better the conductor‚ the all the more quickly warmth will be exchanged. Metal is a decent conduction of warmth. Conduction happens when a substance is warmed‚ particles will acquire vitality‚ and vibrate more. These atoms then chance upon adjacent particles and exchange some of their vitality to them. This then proceeds with and passes the vitality

I have chosen to use Donald Schon’s (1983) model of reflective practice to reflect on my experience of leading the change in the school environment. I feel this was the most suitable model as it allowed me to reflect-on-action how I executed the task (Schon‚ 1983). I have been implementing a change in the primary school where I work. As a teaching assistant I feel confident in suggesting changes we could put in place‚ however‚ this project enabled me to enhance my development and initiate a change

Introduction The natural source of both plasma and electromagnetic radiation (EMR) is the sun. There are various similarities such as the presence of electric and magnetic field in both EMR and plasma. Both transport contain energy and are ubiquitous in the universe. However‚ there are large differences between EMR and plasma. Differences between EMR and plasma EMR is energy that propagates through a medium in the form of EM waves. It has an electric and magnetic field which oscillate in

Calculating the Enthalpy Change of Reaction for the Displacement Reaction between Zinc and Aqueous Copper Sulphate Data Collection and Processing Observations: * Drops of water left on the inside of the measuring cylinder * Hole in the lid‚ possible escape route for gas or splash-back * The polystyrene cup felt warm during the reaction By extrapolating the graph we can estimate what the rise in temperature would have been if the reaction had taken place instantaneously. I can

The Rutherford Model of the Atom 1. In 1911 Rutherford proposed the nuclear model of atomic structure. He suggested that an atom consists of a central nucleus (where most of the mass of the atom is concentrated) having a positive charge‚ surrounded by moving electrons carrying negative charge. Geiger and Marsden carried out an experiment to verify his proposal. The Geiger/Marsden a Particle Scattering Experiment 1. The apparatus is illustrated in the diagram below. | 2. The apparatus

Sameera Raziuddin Latent Heat of Fusion April 11‚ 2011 Abstract: A calorimeter‚ water at room temperature‚ ice‚ and a Pasco GLS Explorer were used in combination with a known value of the latent heat of fusion to create and carry out an experiment to determine the mass of an unknown amount of ice. Using the formula for latent heat of fusion‚ the mass of the ice was calculated to be 45.76g. The error of the carried out experiment was calculated to be 20.06%. Introduction:

Purpose The purpose of this experiment is to test Coulomb’s Law which states that the force between two spherically symmetric charged objects is directly proportional to the product of the charges‚ and inversely proportional to the square of the distance between the centers of the two charges. In mathematical vector notation Coulomb’s Law is expressed as where Fr is the force on particle 1 due to particle 2 in Newtons‚ q is the charge on 12 1 particle 1 in Coulombs‚ q2 is the charge on particle

Reflective Practice Introduction: Reflection its self is looking into personal thoughts and actions. For nurses this would mean looking at how they performed a particular task taking into consideration their interaction with their colleagues and other members of staff‚ patients and in some cases relatives This then enables the nurse to assess their actions and thought processes. There are various frameworks of reflection that one could choose and the examples used for this work
