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.

necessary to produce a temperature change of 1°C per gram of substance. The specific heats of different substances vary‚ and therefore this quantity may be useful in identifying an unknown. The measurement of heat changes is called calorimetry. In this lab activity‚ calorimetry will be used to determine the specific heat of an unknown metal. This will be done by using a styrofoam cup calorimeter containing water. A calorimeter is insulated so as to minimize any loss of energy to the surroundings. Therefore

Experiment-5 Thermal physics is the combined study of thermodynamics‚ statistical mechanics‚ and kinetic theory. This practical is done to measure the temperature drop of water over a period of time (30 minutes). Research question- What is the rate of temperature change over a period of 30 minutes? Independent variable- time Dependent variable- the temperature of water Controlled variables- the amount of water in the calorimeter - The stop watch

Conservative force - Any force which conserves mechanical energy‚ as opposed to a nonconservative force. See statement of conservation of mechanical energy. Conservative System - A system in which energy is conserved. Energy - The ability to do work. Kinetic Energy - The energy of motion. Nonconservative Force - Any force which does not conserve mechanical energy‚ as opposed to a conservative force. Path independence - Property of conservative forces which states that the work done

Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 | Instructor: Mr. Nailer | I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT)‚ its mass (m)‚ and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine

Purpose Determine the acceleration in a quick sprint. Question What would the participant’s acceleration be if he/she sprints forward in a positive direction? Hypothesis/Prediction When a person sprints forward‚ it means he/she speeds up. Consequently‚ the acceleration should be positive. When the velocity accelerates at a constant rate‚ the acceleration should remain constant. Therefore‚ if the participant is moving toward a positive direction and the speed increases‚ then the acceleration
