The Effects of Force and Mass on an Object’s Acceleration Abstract: In this lab there were two principals investigated. The first was the relationship between applied force and acceleration. The second was the relationship between mass and acceleration. To study these two relationships‚ my partners and I used a dynamic cart with added mass on it. This cart was then attached to a pulley system on a “frictionless track” where it was pulled by a string bearing mass over the edge

Subject: Chemistry Topic: The Periodic Table The periodic table is a classification of all the elements based on ATOMIC NUMBER. It is composed of HORIZONTAL PERIODS and VERTICAL GROUPS which contain the elements arranged: *the order of INCREASING ATOMIC NUMBER *in the relation to the ELECTRON STRUCTURE of the atoms *in the relation to their CHEMICAL PROPERTIES (Criteria Used For Placing ELEMENTS in the Periodic Table) 1. ATOMIC NUMBER 2. NUMBER OF SHELLS (PERIOD) 3. NUMBER OF OUTER

When reading the 12 tables laws of Rome‚ I am half chuckled but yet was appalled by some of the preposterous things they considered laws. If a man had a grievance with another and filed a court case against the other in the court then he had a certain amount of time to wait for the defendant if you will to show up. If the defendant didn’t show up or fled the plaintiff could then arrest him. Honestly what if the plaintiff was conjuring up the grounds for the case to begin with and the entire time

Motivation Concepts Table and Analysis Motivation Concepts Table and Analysis Motivation describes how an individual behaves and the reason(s) why he or she behaves in that way. Many psychologists have developed theories and study the behaviors of individuals to determine the motivators that cause certain behaviors. An individual’s behavior is influenced by his or her needs and wants. “Theories of motivation are created to help us explain‚ predict‚ and influence behavior” (Stipek‚ 2006-2011). Psychologists

Aaron Wong History and Development of the Periodic Table Period 11 The most basic arrangement of the periodic table was in 1649. By this time‚ many elements have been known but the first scientific discovery of an element was in 1649. Hennig Brand discovered phosphorus‚ the first element discovered through scientific inquiry. He attempted to create a Philosopher’s Stone which was supposedly able to turn metals into pure gold. During his experiment‚ he

Who invented the periodic table? Dmitri Mendeleev invented the periodic in 1869‚ 5 years after John Newlands put forward his law of Octaves. Part of Dmitri’s periodic table He realised that the physical and chemical properties of elements were related to their atomic mass in a ’periodic’ way‚ and arranged them so that groups of elements with similar properties fell into vertical columns in his table. He also stated: The elements‚ if arranged according to their atomic mass‚ exhibit an apparent periodicity
