we dedicated a whole day to our beloved Earth due to our space race with the Soviet Union. If NASA had never transmitted the picture of Earth to Earth when they did‚ would there not have been an Earth Day created? The picture alone of “the blue marble” had sparked the peace movement and was a new symbol that embodied

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

POWDERED MARBLE AS ALTERNATIVE TO COMMERCIAL CERAMIC TILES Class Project in English 104 (Technical Writing) Abstract This study determined whether powdered marble can be used as substitute to ceramics in the manufacture of commercial tiles. It especially determined and compared the water absorption‚ crazing resistance‚ chemical resistance‚ and breaking strength of 59%-50% and 75%-25% powdered marble tiles‚ and the commercial ceramic tiles.

Linear Kinematics. Fielding a backhand requires acceleration and deceleration. The fielder must accelerate towards the ball and decelerate when approaching the ball to field it. Acceleration occurs in the first three phases of the backhand and deceleration occurs in the critical phase‚ drive phase‚ when the fielder picks up the ball with their glove. Acceleration helps the athlete gain distance between the fielding positon and the ball. This allows the fielder to get their glove in front of the

REPORT2013JAN-PHISICS Group: LUCA Does mass/weight affect acceleration? Hypothesis: The heavier the car the slower ( the more the mass the slower)‚ the more weight(force) we added the faster. Experiment: Materials: Trolley Elastic cords for accelerating trolley Rod for attaching elastic cord to trolley Ticker-timer with power supply unit Ticker-tape Sellotape Process: 1.Thread a length of ticker-tape through a ticker-timer and attach the end to a trolley. 2.Pull a trolley with a fixed

physics honors Acceleration due to gravity by picket fence method Varun Kumar Pd 7 Saumya Kapoor & Tonia Li 9/26/2014 INTRODUCTION Acceleration is the increase or decrease in velocity. It can also be described as the rate of change in velocity. Acceleration is represented by the formula: . In this experiment we look at a specific type of acceleration‚ Free-Fall. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. There are two important

This assignment entailed the task of investigation into the a) Conditions under which corrosion is accelerated‚ and b) Methods of preventing corrosion. Two experiments were implemented to answer these questions and hence reach a definate conclusion.First off let’s look at the background of corrosion and the way in which it occurs.The first hypothesis to answer was‚ ’What affect does water temperature have on the rate of corrosion of iron in sea water?’ The assumed answer was that ’ As temperature

garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences in the acceleration to determine how the ring and the disk resist rotational
