Each section must be present in a complete report. Purpose: The purpose of this lab is to give the student a better understanding about. Task: Velo Sensors of Sensor A velo sensor is a crucial tool that is used to determine the rate of change of position of an object. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. This is not one of them. The important part of this experiment was the temperature.
Note this is Newtons first law about motion, an object in motion will stay in motion. The wavelength of the sound will be determined by making use of the resonance of an air column. In this ultimate equation, f is taken as the frequency while l is the wavelength. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Download file to see previous pages Sound is often part and parcel of our entire surrounding and has great significance in our daily life. The apparatus consisted of a plastic tube filled with water linked to a water container. Jacobs Abstract In this experiment, we test factors which effect friction.
Fill the graduated cylinder nearly to the top with water, with a tall glass tube open at both ends the water level with act as the closed end. Bayesian analysis was used to set meaningful values on the uncertainty of our limits. Bechtold April 7th, 2014 Question: Will the average speed of sound using resonant lengths and the speed of sound using the temperature be the same? Thiscontainer could be displaced vertically in order to change the water level. In this experiment, we use standing sound waves created by the tuning forks to determine the speed of sound in air in a tube when it reaches different resonances. Where are a node and an antinode occuring in the sound standing wave in this lab experimental set up? Acceleration, Experiment, General relativity 1078 Words 4 Pages Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements halogens and their compounds.
Dependent Variable: Time taken of the domino effect. The velocity sensor is based on the movement further from the starting point of the object. In fluids like air, sound waves propagate through successive longitudinal perturbations of compression and decompression. You will need this sheet to record your data. Both of the percent discrepancies for the elastic collisions were close to the 10%-15% range which validates the concept of momentum conservation in inelastic elastic collisions. The speed of sound is a physical property that can be measured easily in the lab. Head loss in piping system.
Conclusion The purpose of the experiment was to investigate simple elastic and inelastic collisions to study the conservation of momentum and energy concepts. Experiment, Laboratory, Logic 1036 Words 4 Pages Miriam Karunakaran Physics Honors Period 6 Physics Kinematics Lab Report Kinematics is the study of the motion of bodies without reference to mass or force. Here we discuss an application of this method that simplifies Newton's law of cooling. Speed of Sound Lab Will Guo 1126 Reads Next Leave a Comment You must be logged in to leave a comment. Hypothesis: Yes, the two different ways of calculating the speed of sound calculating the speed of sound by using the resonant lengths and the temperature will have the same result.
There are other methods to determine the speed of sound. Establish an angle and let the ball swing for 10 oscillations, timing it and stopping at the 10th one. This will follow the standard format for a lab report and should include the following sections: Title Introduction Materials and Methods Results Discussion Conclusion. The report is divided into several well-defined sections. Aerodynamics, Fluid, Fluid dynamics 838 Words 4 Pages Speed and Radius Question For an object moving with uniform circular motion, what relationship exists between the radius of its path and its speed? You end up with a table of data giving distances. When the rod set into vibration through proper stroking, the standing waves are hence produced within the vibrating rod.
After conducting our experiment and calculated our data, we found out that the speed of sound for the lab was only 100. Hypothesis I believe that the speed of sound it the air will be close to that of the predicted value. And also to all my group mates especially to the leader to make this report good job and well done. To determine the speed, a resonance tube full of water was used and two different tuning forks of known frequency. Noise Pollution Introduction The normal definition of noise is a disturbing sound,. Controlled Variable: The number of dominoes used 8 dominoes , the distance between the dominoes 2 cm , the loads used as the initial force applied on the domino 50g , the inclined plane used as a platform that will direct the load to hit the first domino 20o , the stopwatch used to time the domino effect, the person using the stopwatch, the person releasing the metal weight from the top of the inclined plane, the ruler used to measure the distance between the dominoes. Secondly, to determine the optimal temperature for the two amylases, this is the temperature these enzymes function at best.
Velo involves the use of time, speed, and direction. Understanding the graphical representation of. To use the resonance to determine the velocity of sound in air at ordinary temperatures. More specifically, the solubility properties of these halogens will be used to predict their reactions. Resonance is indicated by the sudden increase in the intensity of the sound when the column is adjusted to the proper length.
That, plus the fact that all the starting and finishing materials are non hazardous and safe, is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants vinegar and baking soda is the limited. The Speed of Sound experiment was developed by Da Silva et al. To determine the dissolved oxygen content, the LaMotte Kit or Winkler Method was used. Present the results and analysis in a formal. The pedagogical advantages of this conceptually simple experiment are also discussed. The sound frequency was then determined by use of wave motion concept.
This paper deals with the comparison of sound speed measurements in air using two types of sensor that are widely employed in physics and engineering education, namely a pressure sensor and a sound sensor. The error on the length was estimated to 0. A set of audio files with selected frequencies is first created and stored on the student's computer. This point in space is usually referred to as a node. What question is it trying to answer, or what problem is it trying to explain? Meanwhile, for freshmen, the speed of sound experiment was categorised into three parts: accurate value 52. These tests were the startle, stroop, Valsalva maneuver, diving reflex, and a test of our choice.
