1. Determine the spring constant‚ k‚ of Spring 1‚ by using Hooke’s Law. Take three different measurements (since 3 masses) and do three calculations and average your k’s to get a more accurate answer. By applying lots of friction‚ you will be able to get your mass to hang still. Show a table of your data and your calculations of k. Spring 1 with three different masses: 50 grams: Spring stretched: 5m F = 50gm * 9.8 m/s2 = 490.00 N K= 490/5m = 98 100 grams: Spring stretched: 10m F = 100gm * 9

Unit 4 Research Paper Assignment 1: Using Global Variables 1. Five advantages of using global variables • It is accessible to all modules in a program • You only have to declare it once outside the modules • It is good to use it for constants you want to keep consistent • It simplifies maintenance‚ avoids duplication of local constants • It can make a program easier to read in reference to constants Five disadvantages of using global variables • It makes debugging difficult • Any statement

THE THIRD-VARIABLE PROBLEM Correlational data are frequently misinterpreted‚ especially when presented by newspaper reporters‚ talk-show hosts‚ or television newscasters. The Most common problem in interpreting correlations is Third-Variable Problem. A correlation simply indicates that there is a weak‚ moderate‚ or strong relationship (either positive or negative)‚ or no relationship‚ between two variables. When interpreting a correlation‚ it is also important to remember that although the correlation

1. INTRODUCTION 1. OVERVIEW In order to achieve several small scale and large scale objectives in various electronic circuits‚ it is highly essential to regulate the voltage supply‚ given to electronic circuits. This project‚ namely VARIABLE VOLTAGE REGULATOR‚ aims at fulfilling such small goals‚ using the 3-terminal voltage regulator LM317. The circuit consists of an IC LM317 and a set of resistors and capacitors‚ in addition to the transformer and the rectifying element. The AC

Vanessa Gale Formal Lab: Evaluation of the Gas Law Constant Dr. Monzyk Due 06/25/2012 Purpose: The purpose of this lab is to evaluate the gas law constant. The ideal gas law is represented as PV=nRT‚ where R represents the gas law constant. To determine R‚ we must find the other parameters‚ P‚ V‚ n and T through the experiment. Equipment and Materials: Large beaker Ring stand Clamp Copper wire 100 mL eudiometer tube Magnesium (Mg) ribbon M6 H2SO4 (Sulfuric Acid) Wash bottle

Straight Line Equations and Inequalities A: Linear Equations - Straight lines Please remember that when you are drawing graphs you should always label your axes and that y is always shown on the vertical axis. A linear equation between two variables x and y can be represented by y = a + bx where “a” and “b” are any two constants. For example‚ suppose we wish to plot the straight line If x = -2‚ say‚ then y = 3 + 2(-2) = 3 - 4 = -1 If x= -2 -1 -1 1 0 3 1 5 2 7 As you can see‚ we have plotted the

the same thing. True 3.) A statement on one module can access a local variable in another module. False 4.) Programming languages typically require that arguments be of the same data type as the parameters that they are passed to. True 5.) When an argument is passed by reference‚ the module can modify the argument in the calling part of the program. True 6.) Passing an argument by value is a means of establishing two-way communication between modules

Determining the Absorbance Maximum Wavelength and Molar Extinction Coefficient to Find the Molarity of the Unknown DCPIP Background Information: A spectrophotometer is an instrument used to help determine the absorption spectrum of chemicals. It does this by reading the absorbance of the chemical at different wavelengths. All chemicals absorb light in their own distinct way. This distinction helps to identify unknown chemicals. The absorption of light within a chemical is also very important because
