The purpose of the lab was to find which combination of motor and propeller should be used to power a car. In order to do so, we needed to build a force gauge that could accurately measure force. To be able to measure force, we needed to understand what force is. Force is simply explained as an interaction that, when unopposed, will change the motion of an object. During the lab we wanted to measure force for a simple reason;it was our job. Our job, as described by Power dynamic corp., is to build a device that can accurately measure force, if we do not measure force than we can not do our job. The force that we calculated during our lab was of the force produced by three different fan. We wanted to measure the force of the fans so that we …show more content…
The first was when it came to assembling the motor wiring. The first couple test we were lucky and put the wiring on the right tab.Then the fourth testing came around, and an anomaly in the behavior of the fan accord; it was pushing the motor and spring up not down. We then took down the whole assembly and put it together again and that's when we realized that the tabs were labeled. When a positive or negative wire and tab came in touch, the fan would spin up. We switched them around and that when the fan spun down. We realized how important the electrical tabs and wires were. Not too long after the previous incident did we come across another problem. During our measurement, the fan would wrap the wires attached around itself. This excessive resistance caused our measurements to be off. We tried to length the wire,but all that did was add more wire to wrap, We then tried to shorten but that added even more resistance. After looking at the battery contraption we decided to move the battery from the top stachio to the side stanchion. This stopped the spinning and we got much more accurate data. The final problem that we encountered was more broader than all the other problems. During our measurement, we had been measuring wrong. We had been using a tape measure that had a metal loop on the bottom. We believed that the metal loop was for accessory and was not to be used to measure with. However, we learned that the bottom of the metal loop was the 0 cm mark. After learning this we had to remeasure all of our data due to this
Cadet Eric Wiggins Date: 18 September 2014 Course Name: Chem 100 Instructor: Captain Zuniga Section: M3A Identification of a Copper Mineral Intro Minerals are elements or compounds that are created in the Earth by geological processes. The method of isolating metals in a compound mineral is normally conducted through two processes.
3. You then add the inches lost for the measurement sheet onto the white board, making sure the measurements are taken in the current month. Eg. If it is Presently December, make sure the measurements have been taken in December by checking the date on the measurement sheet.
After turning on the power supply, the current was adjusted to 5 different levels using the voltage knob, and the magnetic field at each current level is recorded. However, the voltage knob was turned to the left thoroughly, immediately after each current level to prevent the sensor from overheating. Since the data taken for the magnetic field was in Gauss, we converted to the Tesla. At last, we calculated the magnetic field and the percent errors of calculated and measured magnetic field using the equations. Part II: Magnetic Force
Introduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.
According to your lab instructor, unhook the spring and remove the hanging mass from the centripetal force apparatus and determine the mass Hanging by using a balance. The radial indicator at the one extreme position. Used Vernier caliper to measure the diameter of the center pole, which is on centripetal force. Three times students have to measure the length of the pole, and at the end get an average.
Introduction: In this lab, we measured the angular velocity of the sun (how fast the sun rotates on its axis) to find the time it takes for the sun to make a complete orbit. We did this by printing two images of the sun that are 7 days apart from NASA’s SOHO database to observe and measure one sunspot (the same sunspot in different locations on both images). We looked at sunspots because its dark (due to magnetic activity and heat transfer) and easy to identify since there are few spots from a faraway perspective. were able to solve for the time period it takes for the sun to rotate on its axis using the following formulas: θ=sin〖x/(R ')〗 where R’ is the radius of the circle the sunspot orbits, 〖θ=sin〗〖x/R_sun 〗 , where R_sun is the radius
Intro Binary stars consist of two stars orbiting around their common center of mass. Majority of the visible stars in the sky are binary star systems. For instance, Algol, Alpha Centauri, Sirius and Antares are binary star systems.
The DTE distinguishes our actions on an “in order” or “because” basis. In the 6 behind 1 case, the ones death can be justified because we change the switch in order to hit the one, not because we want to hit the
As with other formulas galvanometer has its own formula called a=the angle of deflection of the coil. Although, the currency of moving coil meters is dependent upon having a uniform and magnetic field. Is a very sensitive instrument used to measure the small currents of the order. Galvanometer gives the deflection which is proportional to the electric current flowing through it. It works as an actuator by producing a rotary deflection.
This is evident due to the handprint placed on the wall was made with a right hand. Only customer that would use the right hand to rest on the wall after using his dominant left hand to trigger the
Each ecosystem has their own biodiversity, differing themselves from other ecosystems. In our experiment we are revisiting how the intensity of light effects the movements of Gammarus setosus. From J. M. WeEsøawski, M. ZajaÎczkowski, J. Wiktor (1997) report, when there are Macrofauna taxa and Macrophytes, there would a frequent amount of Gammarus setosus. With this we can conclude that Gammarus setosus plays a large role in the food chain. By getting more information of the Gammarus setosus we able to get more information for future research into the how prey and predation with the Gammarus setosus.
I believe this experiment started when my professor planted this "un-occupied, un-employed" thought in my head. In this pre-experiment phase, I had a blind vision. We as students are trained to hypostasize before an experiment but as much as I wanted to predict what was going to
Hypothesis: The physics according to Newton’s law and physic in general in the movie is accurate with, however, a few over-exaggerations and folliness. Definitions of the concept dealt with: The research project is used to prove and explain how the physics in the movie ‘Gravity’ is accurate with reference to Newton’s laws. Newton’s
Another item that most ghost hunters use is EMF meters. EMF stands for electromagnetic forces which was first noted in the Victorian era. However, the EMFs were unable to be read until we reached into today’s world because the technology just was not there. EMF meters are used to measure the strength of the electromagnetic force that an item, be it appliance or ghost, gives off daily. Investigators use these meters to measure ghost energy.
The purpose of examinations that Feynman describes is to verify that an individual understands the subject and is able not only to define words but also give examples. 3. The students describe pressure such as being told to not ask questions because they interrupt the lecture time. 4. Feynman recommends science should be taught along with experiments.
