Photoelectric Effect: Determining Planck’s Constant Friday‚ Section 006 TA: Yilikal Ayino John Greavu with Daniel Erickson & Kevin Haar January 31‚ 2014 PreLab Up until the eighteenth century‚ particle theories of light dominated physics‚ primarily due to the work of Isaac Newton. Thomas Young’s 1805 famous double-slit experiment‚ which showed that light mimics a wave‚ extinguished some of these early views. However‚ in 1887‚ Heinrich Hertz – who is‚ coincidentally‚ perhaps better known for definitively

I. Abstract This experiment aimed to determine the composition of Ni2+- ethylenediamine (en) complexes through Continuous Variations method as well as the number of ligands (n values). This nondestructive method is preferred in determining the amount of complexes present which will also not disrupt the equilibria. 0.3M concentrations of nickel sulfate hexahydrate and ethylenediamene are mixed at certain stoichiometric ratios of 0.3‚ 0.4‚ 0.5‚ 0.6‚ 0.7‚ 0.8 and 0.9 to form several complexes.

English 101 Wed. October 9‚ 2002 Comparison Essay Breastfeeding vs. Formula Feeding Feeding your new baby is one of the first activities you accomplish as a mom. As a new parent‚ it is your responsibility to make sure your baby will get off to a good nutritional start. To do that means‚ you must decide what is best for you and your baby‚ whether to breastfeed‚ or to formula feed. Both choices have pros and cons‚ but it is totally up to you to choose which is best for you and your child. There

Intelligence In my high school your intelligence level is based on your ability to master material in difficult courses‚ which is quite different to people the same age in the Amazon rain forest. Their intelligence level is based on their knowledge of the medicinal properties of local plants. In both of these very different locations intelligence is the ability to learn from experience‚ solve problems‚ and use knowledge to adapt to new situations. General intelligence is also known as the g

Real World Radical Formulas MAT222 Intermediate Algebra Real World Radical Formulas This week’s assignment involved solving real work radicals. We were required to solve two problems on pages 605 and 606. While this assignment was not easy for me‚ I feel like I most definitely learned something new. The problems involve sailboat stability and speed. I will be looking for the capsize screening value and the sail power of the sailboat. Page 605 Problem 103 Sailboat Stability

Land surveying has been a challenge for many years both in developed and developing countries. For instance the triangular survey consumes a lot of time as several sides of the field need to be measured. Solutions to this have been reached by the discovery of M utua’s formula of finding the area of a triangular shape. 1.0 Introduction

DETERMINING THE GLUCOSE CONTENT OF AND ORANGE USING GOD-PAP ASSAY Every fruit has a sweet taste only that some are sweeter than others. The sweetness of most fruits come from its sugar content and these sugars that the fruits contain are known as invert sugars. In this experiment‚ an orange was used. An orange which is an excellent source of vitamin C gets its sweetness from natural sugars which are sucrose‚ glucose and fructose (livestrong.com). In this experiment the concentration of glucose in

What is it meant by relative formula mass? How is it calculated using the periodic table? Each element has a relative atomic mass. When a compound is made‚ these relative atomic masses are added together to calculate the relative formula mass of the substance. For example the atomic mass of Na is 23 and the atomic mass of Cl is 35.5 so the relative formula mass of NaCl is 58.5 How by using RFM is it possible to work out amounts of a substance in terms of moles? The compound I was using in my
