It was difficult to keep my eye on the exact spot of the first harmonic and then take a measurement. On the first week, we learned and played with some robots such as Roboquad, Robosapien and Tribot. In this experiment, relative density is also used to be able to determine the composition of the substances or objects used. Its Utilization averages 42% for downloads and about 2% for uploads. Additionally, I believe that my altitude and the amount of humidity in the air contributed to the error.
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. These would both account for the percent error I found. Thiscontainer could be displaced vertically in order to change the water level. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes, walls, furniture; in soil and dust; and on and in our own bodies skin and mucous membranes. Your lab report for this semester will be a write up of your independent research project. Words: 826 - Pages: 4. The person we did the experiment on was Louis Gallo.
Select a tuning fork and record the frequency in Hz in the data table. It is of great importance to recognize and identify the different instruments and laboratory tools, because in this way will we be able to use them properly and also to call them by name and know why. Set Up the Experiment: Place the open ended tube into the water, and verify that it can produce a resonance tube. To determine the dissolved oxygen content, the LaMotte Kit or Winkler Method was used. After bouncing off from the closed end, the sound would hit the microphone; the computer would displace a graph, which shows the initial sound and the echo. The important part of this experiment was the temperature.
I also think that the equation used to find the actual speed of sound was idealized and could contribute to a small and varying amount of error at different temperatures. Copyright © 2012 Advanced Instructional Systems Inc. Acceleration, Analytic geometry, Classical mechanics 1079 Words 4 Pages dye in the flow visualization pipe illustrated the character of the flow. Record observations about the purpose of each tab Advance tab- shows what properties are available for the network adapter Driver tab- shows detail of the driver Details tab-shows device description Resources tab- shows the range of the resources Power management- shows different ways to save power Are any resources conflicts reported? The initial separation would consist of some species from the mainland reaching the isolated Island, then after that the isolated population would begin to diverge because of the genetic drift and natural selection, then after that overtime divergence may eventually become sufficient to cause reproduction isolation. What are the topics for additional information? Words: 482 - Pages: 2. I also worried about getting a proper measurement for the length of the water level to the top of the tube at the point were resonance was at its highest. When a resonance is found, a pronounced reinforcement of the sound will be heard.
It explains how sunlight helps in releasing plant growth regulators in plants which enhances plant growth. After the sound reflects off the opposite end of the tube, a graph will be displayed showing the initial sound and the echo. Be sure you clean your working space after you complete the experiment. It moved right, left, toward and backward really fast. You will need this sheet to record your data. Abstract This lab focused on the effects of varying temperatures on Bacterial and Fungal Amylase enzymes and their ability to break down starch into maltose using iodine.
Apparatus: resonance-tube apparatus an open ended tube which can be moved in and out of a container of water constant frequency source tuning fork or computer generated tone rubber hammer meter stick rubber stopper Procedure: 1. A student would make small waves, while another would time it with a stopwatch until it reaches the other side. For this reason we hypothesized that. This calculation is shown above in the previous section. Explain what the study is testing and why 2 marks.
For each flow state, water discharged was collected from the flow visualization pipe in the graduated cylinder and the time was recorded. Do not leave empty pages to insert information later. Hypothesis: I believe that the racket ball will have a faster average speed than the tennis ball for both distances because the racket ball is bouncy. Make sure that you include the following: 1. Responding Length of air column in the tube, l ±0.
And also to all my group mates especially to the leader to make this report good job and well done. Research question: How to determine the speed of sound by using the relationship between the frequency of the signal generator, f and the length of air column in the tube, l. If you make a mistake, just draw a single line through it, not a childish scribble to hide all traces! As stated earlier, this could be corrected by introgration of a measurement device onto the outside of the tube. Repeat steps 2-4 another 2 times so that your results are reliable. Bernoulli's principle, Choked flow, Fluid dynamics 1380 Words 6 Pages checkerboard was visible again.
