Lab Assessment Questions & Answers 1. What is the significance of creating Groups and adding Users to Groups? Explain. It is important to put user in groups because it is easier manager there permissions. Instead of assigning permissions to a new user every time someone is hired‚ you would just add them to the groups they need. 2. Given a scenario where there are five (5) database administrators that may periodically need access to a given system. Discuss a concept to better manage these administrators’

Appendix Abstract: This experiment is intended to introduce the basic concepts of the operational amplifiers and to help us better understand the relationship between the resistances and the amplifier gain. The main experiment focused on op-amps of which we have two types‚ inverting and non-inverting. With the inverting op-amps there is no current

I. Abstract: This experiment tests two parameters‚ deflection and strain‚ associated with a simple truss subjected to a loading at its bottom end as would be the case if a constructed bridge was subjected to loadings by cars‚ trucks‚ trailers‚ pedestrians‚ etc. The set up contained an instrumented truss mounted in a test frame with strain gauges attached to the center of each truss member and a linear potentiometer displacement transducer (LPDT) placed underneath the truss assembly to measure displacement

Name:_______________________________________________Date:____ _____Block:______ Diffusion In Agar Cubes Is Bigger Better? OR Is Smaller Smarter? Adapted from Flinn Scientific Publication No. 10110 Introduction: Diffusion is one of the very important processes by which substances such as nutrients‚ water‚ oxygen‚ and cellular wasted are transported between living cells and their environment. This activity will help you explore the relationship between diffusion and cell size by experimenting with model “cells.”

Simple Pendulum Experiment In this experiment you will make a simple pendulum consisting of a plumb bob and a piece of string anchored at two points. By attaching the string to two points the normal precession that would occur will be eliminated. [pic] Items to be turned in as report: 1) all discussion question answers (be thorough) 2) graph of period squared versus length 3) simple data tables of collected data 4) graphical analysis answers 5) using your values for g‚ calculate

1. Describe the function of the following pieces of safety equipment and how each might be used: a. Eye wash- To be used in the event of a chemical splash to the eyes. Should be used to flood the eyes for at least 15-30 minutes with water‚ flooding from the eye outward. b. Fire Blanket- To be used in the case of a small fire. Would be tossed onto flames to suffocate the flow of oxygen. c. Shower- Safety showers are designed to flood your body with water in the event of a fire or chemical spill
