Coulomb’s Law 1. Objective - To study the validity of Coulomb’s law on a simple electroscope. This will be split into two parts; first measuring the the force as a function of distance‚ and second we will look at how the magnitude and sign of the charges affect the force. 2. Theory- As is well known‚ like charges repel and opposite charges attract. That being said‚ the strength of those forces also depends on the distance between the two charges

against slavery due to the serious moral and ethical dilemma associated with the practice of slavery. Leading statesmen who oppose the old constitution in the United State of America‚ argued that the enslavement of the African was in violation of the laws of nature; and that is was wrong in principle‚ socially‚ morally and politically. The slave trade at the time was so profitable for the people that were involved in it’s practiced‚ the Abolitionist‚ were opposed by a pro-slavery West Indian lobby.

Lab: Gas Laws Purpose: Obtain a reference of temperatures effect on gas using Charles’ law when heating a capillary tube in water on a heated hot plate. Then‚ cooling the same capillary tube with ice while measuring the temperatures cooling effect on the gas bubble inside the capillary tube. Measurements of temperature change are taken with microLAB sensor and graphed using microLAB software. A final determination of experiments determined absolute zero versus actual absolute zero will be

pneumatic trough‚ thermometer‚ screw clamp. DISCUSSION The quantitative relationship between the volume and the absolute temperature of a gas is summartzed in Charles’law. This law states: at constant pressure‚ the volume of a particular sample of gas is directly proportional to the absolute temperature. Charles’ law may be expressed mathematically: V ". T (constant pressure) V = kT o‚ : T = k (constant pressure) (1) (2) where V is volume‚ T is Kelvin temperature‚ and k is a proportionality constant

Newton’s Three Laws Newton’s three laws of motion are laws or “rules” as to why objects move or don’t move they way they do. They tell us why things that move or at rest stay that way‚ or why the speed up‚ or simply what kind of things it takes to move objects. Newton’s three laws are very important because before he discovered these no one really knew why objects did what they did‚ they simply just did it. I care about these laws because I’ve learned so much that I never really understood nor knew

Name: _____________________________________ Block: _________ Date: _______________ Lab #14: Boyle’s Law Objective: To determine the relationship between the pressure and volume of a gas at constant temperature. Introduction: The relationship of pressure to volume for a gas in a rigid container was first described in 1662 by the Irishborn scientist Sir Robert Boyle (16271691)‚ and is known as Boyle’s Law. As long as the temperature of the gas remains constant‚ the pressure

Main idea #1: If something is moving‚ it has momentum. Impulse is change in momentum. The product of mass and velocity mass*velocity vector because it has both magnitude and direction the product of the amount of force on an object and the time during which the force is applied

S74 assignment Introduction Sir Isaac Newton’s second law describes how the mass of an object changes the way that it moves when acted upon (Jacplus 2013). This means that the more mass that an object has‚ the harder it will be to move. Mass can be calculated using the formula: F=ma * Where: F is the force (N) * m is the mass (kg) * a is the acceleration (m/s/s) If there are two balls and one has a mass of 1kg and the other has a mass of 2kg‚ then the ball that has a larger mass

Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often

Michayla Roberts October 24‚ 2012 Sir Isaac Newton was one of the world’s most intelligent inventor/ scientist/ mathematician/ and physicians. During his time period he accomplished many things the world still benefits from today! Newton started to make all these accomplishments first when he was getting his formal education‚ then during his professional and adult life. Newton’s early life isn’t what you would expect for one of the greatest scientist in history. He was born of December
