EXPERIMENT 2: Measurement of equivalent radius‚ bulk density and solid density of granular materials INTRODUCTION Granular material is a group of distinct macroscopic particles‚ composed of grains or particles of solids with interstitial spaces‚ which are the spaces between the particles. Having spaces between the particles means that there are rooms left for the filling of air or liquid. This concept is applied as to use the filling of liquid to determine the volume of the particles later

INTRODUCTION: This is a standard circuit which can be used to adjust the brightness of mains lights and the speed of AC motors. It uses a triac‚ diac and has a radio-frequency interference (RFI) noise suppression circuit built into it as well. The circuit controls the average power to a load through the triac by phase control. The AC supply is applied to the load for only a controlled fraction of each cycle. The triac is held in an OFF condition for a portion of its cycle then is triggered ON at

will investigate the properties of mechanical waves such as a longitudinal wave‚ focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure/ Planning Procedure: 1. Three students would get into a group. 2. A Slinky would be

The Physics of Star Trek – Warp Speed “Engage.” One simple command that triggers an entire series of complex reactions deep in the core and within the warp nacelles of the Starship Enterprise. Engage implied not only a command to fly off into the unknown reaches of space‚ but also a revolution of thinking that combined fundamental physics with the innovative ideas of the future. Warp technology‚ as envisioned by the writers of Star Trek‚ can be linked to today’s world of physics: Newton’s third

California High Speed Rail Authority website in 2010 alone green house gas emissions in the U.S. totaled 6‚821.8 million metric tons of carbon dioxide (CO2). Central Valley residents in particular have seen increase in aspiratory ailments. The State Legislature passed Global Worming Solutions Act in 2006‚ which is aimed to reduce statewide emissions by 2020 to 1990 level (17 %).

We chose 54 m of study length because the traffic stream average speed in front of Polytechnics Sultan Azlan Shah is 60km/h. 2. We used cone as a marker so it will easy to capture the speed limit when the vehicles pass by the marker. 3. Three of our group members were assigned to measure and put the cone at the road. 3.3 Collection of data 1. All of our group

Input Data is factual information and it needs to be accurately captured in order to be processed. There are many methods to input data and each situation warrants a different method. There can be several different ways to input the information and it can be done in an automatic fashion‚ as with a computer‚ or it can be done manually‚ as with a human writing the information down. For instance‚ printed questionnaires would best use a special scanning device called an optical data reader that uses
