-Abstract: The aim of the experiment was to determine the gravity (g) on the period (T) of oscillation pendulum has a simple harmonic motion (SHM). A stopwatch was used to measure the time taken for 10 complete cycles, which called oscillations. The length of the pendulum was varied for fixed mass and recorded in table 1. The output result for this experiment was agreed with the theory. The graph plotted and got R2=0.99, which was close to the linearity 1. -Introduction: The motion repeats itself

Act I Scene 1 Homework – Graphing a Wave Name: A vibration is a wiggle in time; a wave is a wiggle in space and time. In this exercise, you will explore that connection by transferring the motion of the second hand of a clock (a vibration, even if a slow one), to a wave. Print out the image of a clock and open the spreadsheet called Grapher. You will find both of them in the same item where you found these instructions. Use a metric ruler to measure the displacement of the tip of the

Have you ever wondered why glass bottles made a sound, kind of like a music note? Well, this paper will explain how this works. The paper will be talking about sound, sound waves, standing waves, musical note names and frequencies, resonance, and closed-end air columns. Closed-end air columns will be a main focus in the paper, studying the physics behind it. Glass bottles are an example of a closed-end air column. Therefore, the more water inside the bottle, the lower the note, and less water would

Rocket Engine Combustion Instability Naveen Penmetsa University of Colorado, Boulder, CO, 80309 C ombustion instability has long been an area of research in the design of both aircraft and rocket engines. Specifically in terms of rocket engines, combustion instabilities occur in every type of engine including solid rocket motors, cryogenic engines, hyperbolic engines, and hydrocarbon engines. Although combustion oscillations tends to exist in almost every engine, the goal is to minimize these variations

basic operation and fundamental arrangement of subsystems is the same. 4.1.1 ANTENNA Recieving wire is an article which utilized as a move between wave spreading in free space, and the fluctuating voltages in the circuit to which it is joined. A reception apparatus either gets vitality from an electromagnetic field or transmits electromagnetic waves created by a high recurrence generator It guarantees that the sign has the obliged example in space. Reception apparatus sources transmit vitality similarly

Abstract As industries expand, utilities become more interconnected and the use of electricity rises, power quality becomes essential to insure a smooth industrial process. The main problem that severely affects the power’s quality is the presence of the harmonics, which affects the performance of the system. Some of the problem caused by the harmonics are metal parts’ overheating, increasing noises in motors, decreasing the efficiency of the motors, etc. some corrective methods can be used to reduce

Optimizing the Performance of a Standing Wave Loudspeaker Driven Thermoacoustic Refrigerator Alamir, M.A., Elnegiry, E.A., Eltahan, H.R. Abstract— This study investigates the design and optimization steps of a thermoacoustic refrigerator. Matlab code will be used for optimizing the stack length and its position. DeltaEC version 6.3b11 will be used to do the code used for simulating the refrigerator to identify the optimized operating conditions such as the frequency, the mean pressure and the oscillating

Nathanael Betz Narrative 1 Knutson 18 December 17 Deep Ocean Surfing At 5:30 a.m. My alarm clock buzzed. It was Wednesday. I thought to myself, school doesn't start for another two and a half hours. I suddenly remembered it's one of the most exciting days that I will experience. Both my parents were sleeping. I turned off my alarm and got out of my warm bed. Immediately I put on swimming shorts with no shirt, to top it off a flat brim hat sitting backwards on my head. I walked into the hallway

The waves form and break in front of me, the sound of them crashing lingers in my ears . Sitting here at the beach, I feel as if the world was still and I was the only one who existed. My toes dig into the warm, golden sand and the pleasure sweeps over me. The slight breeze is twisting my hair into knots but I don’t care. Without a breeze, the beach wouldn’t be the beach. All I hear is the roaring waves crashing in front of me and the smell of salt and sand in the air. My feet hit the icy water and

insignificance within its domain, and more important business for itself. My tiny body amid this vast strange universe, staring at the gunmetal clouds, overcome with motion sickness that I had never experienced before. Otherworldly, the impossible spinning waves tunneled through my cells, and with it this time – the smell of death. It hit like a copper truck slamming into me creating a hole to dump its load of rotten eggs, human waste, cheap perfume, and rotting meat forcing my cells to explode from the inside
