Physics Domino Lab I. Problem: What spacing between the Domino’s will provide the fastest velocity for a line of falling Domino’s. II. Background: The Domino C.I.M. lab that we have been assigned brings forth the question of the compression of a line of Domino’s. The question is‚ what set up of Domino’s has the fastest compression time. We intend on testing this by lining up different strings of Domino’s and finding which variable of distance has the greatest compression velocity

Silveira Date of Submission: September 25‚ 2013 Lab Section: CHE110L*Z Purpose The purpose of this experiment is to use two common laboratory methods to see how mixtures can be separated based on physical properties. Paper chromatography will be used to separate the dye colors from M&M candy to see which colors contain yellow #5. Gravimetric separation will be used to separate salt and sand from a mixture. Procedure The procedure for this lab can be found on pages 16 – 30 in “General Chemistry

Constituent of “Panacetin” Recrystallization& Melting-Point Measurement Organic Chemistry Lab Introduction: Panacetin purportedly includes sucrose‚ aspirin‚ and acetaminophen. However‚ the accuracy of Panacetin’s contents has been called into question by the Association for Safe Pharmaceuticals. Therefore‚ the lab must discover the accuracy of the ingredients listed on Panacetin’s label. The unknown in this experiment is presumed to be something

Rodney L. Bennett Jr ISSC362 Week 1 Lab #2: Implement Hashing and Encryption for Secure Communications Instructor Name: _Adam Meyer_ Lab Assessment Questions 1. Compare the hash values calculated for example.txt that you documented during this lab. Explain in your own words why the hash values will change when the data is modified. The hash file is changed when the data is modified because the information within the file has changed and it is considered a new/different file. 2.

The passalide‚ also known as the Bess beetle‚ are reported to be able to carry 30 times their weight. A scientist names Rodger Kram studies these beetles. But really how strong is the Bess beetle? Does beetle mass seem to affect a beetles pulling power? A way to observe this is by conducting an experiment to see how many pennies beetles of diverse masses can pull. If the beetle mass is related to the beetles pulling power‚ then a beetle with more mass will have a higher pulling power. Materials

In this lab we will look at how molecules move across the membrane of a cell . Osmosis is the movement of water across a cell membrane.In osmosis the cell membrane is selectively permeable‚which allows for the membrane to control what types of substances that passes through.Transportation can either be passive or active.Passive transport does not require the use of added energy where as active transport requires the cell to use energy. Diffusion is the simplest form of passive transport. Using

February 25‚ 2013 Lab: Equilibrium of Forces Purpose/Objective: The objective of this lab was to test the first condition of equilibrium for a set of concurrent coplanar forces‚ prove Lami’s Theorem‚ and to determine an unknown mass using rules of equilibrium. Procedure: In the lab‚ we wanted to find at what angles three separate weights would create a net zero force on a force table so that the ring holding the weights was exactly centered in the middle
