Lab 2 Physics 190 Acceleration “g” Due to Gravity – Method 2 Introduction Tonight we will measure the acceleration due to gravity again. This time however‚ we will collect more data and the analysis will be different. We will first fit the data using a second order polynomial. Recall for a mass falling from rest‚ that 1 (1.1) y a yt 2 2 Suppose a mass falls through n successively greater displacements‚ each time starting from rest. The displacements can be expressed a 2 y y t ;

One aspect of nutrition that is vital is protein. Protein is one of four major building materials in the human body. Proteins are composed of carbon with Hydrogen‚ Oxygen‚ and Nitrogen attached. Some proteins also have Sulfur‚ Phosphorus‚ and Iron. Proteins are made up of sub-units called amino acids‚ of which there are twenty. These are just the basics of what proteins are composed of. Amino acids‚ which are the sub-units of Proteins‚ can be divided into two groups. Eleven of the twenty amino

monitor the status of a person with a known thyroid disorder. The T3 test is usually ordered following an abnormal TSH and T4 test. Either the total T3 or the free T3 may be ordered. Since most of the T3 is bound to protein‚ the total T3 can be affected by protein levels and protein binding ability‚ but the free T3 is not. T3 testing may be ordered along with thyroid antibodies to help diagnose Graves disease‚ an autoimmune disorder that is the most common cause of hyperthyroidism. A total or free

this lab‚ you will explore the relationship between matter and energy by dropping objects made of different materials from different heights to see how high they bounce. You will be dropping these objects in a virtual lab setting where objects behave the same as they would in the real world. Goals for the Lesson Solve a problem using the scientific method. Use the metric system in a scientific experiment. Plot an independent variable against a dependent variable to make a graph. Use graphs

Introduction The purpose of this lab is to determine the percent mass of Cu in a penny and see if the fabricator that makes the planchets for the government is using the correct amounts of Cu in the pennies. The composition of a standard penny is 97.5% Zn and 2.5% Cu. In the lab we will be using Beer’s Law (A=elc+b where A is solution absorbance‚ e is a constant called molar absorbency‚ l is the length in cm‚ and c is the concentration). Using Beer’s Law in this lab a colorimeter is used to find the
