Abstract
Lenz’s Law is one of the most interesting and essential in comprehending the relationship between magnetism and electricity. This experiment is called “The Magical Pipe” on purpose because of the “magical” event that takes place only in magnet. Actually, pipe will be composed of copper that will be put in a vertical position and an object will be released and the falling time for both of them will not be the same. Simply, the aim is to discuss the physics behind this event and the force, which is in the opposite direction of gravitational force that slower the fall.
Introduction and Planning

The objective is to examine how Lenz’s Law can be useful to describe the effects on the free fall and the magnet itself. In this experiment, the pipe will be in the role of an inductor. We know that inductors convert the moving magnetic field into electric field, hence they provide moving electrons. If anything without magnetic field falls in the pipe, we will observe just a free fall. On the other hand, in the case of an object with magnetic field, there will be a force that opposes the free fall. This is the exactly the force that the famous Russian physician H. Lenz stated in his Lenz’s Law. This crucial concept is going to be expanded and be part of the
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
Therefore, the purpose of the lab, which was established as, to see the role that static electricity has on objects, when determining their charge and how they interact, is fulfilled in a wall mannered fashion. This process extends to other objects and real world applications, such as the controlling of electrical cable manufacturing and application in areas such as a television depot station, where static electricity must be managed and accounted for to avoid disruptions. As well as in micro surgery where small mechanical devices and robots must be carefully monitored in electron level in order to preserve machine functionality and efficiency. Therefore, the purpose of the lab is met and the hypotheses was supported, proving the quality and efficiency of the lab being
Planning refers to the efforts put in place to achieve goals that add up to the future (Pfeffer & Sutton, 2006). It is about what is happening today to achieve results and therefore refers to the strengthening of what works while taking informed risks of setting targets. CAMBA’s Park Slope Women MICA Shelter uses performance appraisal tools by way of feedback and making necessary adjustments. They also eliminate programs that do not work. Leaders in non-profit institutions ought to recognize the role of dissident voices by creating environments that fosters innovation through constructive criticism (Nadler, 2004).
UBT1 Task 1: Electricity Introduction What is Electricity? This question is difficult to answer because this is a broad concept of science with multiple definitions. In physics, Electricity is a naturally occurring phenomenon of the flow of electric charge. In other words, the process of attraction and repulsion between electric charges produce electricity. There are two types of charges- negative charges and positive charges.
A lightning rod is a metal rod that is attached to the top of a building that runs down the side to the ground. The electricity is then conducted through the rod and is then buried in the nearby ground. A building that has a lightning rod on it is the Empire State Building. The lightning rod was a very effective force when it came to protecting the building that it was placed on.
To safely tow a vessel at warp speed, the target vessel 's engines had to be deactivated to avoid shearing forces against the towing vessel. A tractor beam could then be used at warp speed only if both vessels ' speeds were matched exactly. Physicists at New York University, David Grier and David Ruffner, have created a tractor beam capable of pulling particles, although they are but micrometers in size. They refer to it as an optical conveyor tractor beam, and it has so many other potential applications, from microfluidics (in the near term to far-out applications like collecting dust samples from comet tails. “This is science fiction made real,” said NYU Physics Professor David Grier, one of the paper’s co-authors.
Having many ideas on the table ensures that the most effective means for the city, as well as the community, are addressed. According to FEMA examples of plans include engineers utilizing structural control, emergency managers using activities geared towards warning/response, and land planners leaning towards regulations (2007, pg. 7). Having a planning committee that includes multiple agencies and groups provide a higher chance of success. The involvement of local stakeholders is essential to an effective plan.
Week 9 Chapter 12 focuses on planning before the class. The author mentions that planning can remind teachers what they intend to do during the class, and it is also helpful for class observation. Although class planning is important, sometimes things do not always on the right track. Therefore, teachers have to be flexible and change the plan accordingly. The aim of the plan is to have coherence and variety.
Requirements Gathering – 4 weeks This is the investigative stage of the project. which involved conception, initiation and analysis of the problem. Design phase – 3 weeks This stage involves translating the requirements from the previous stage into detailed designs that address them.
The lightning rod was intended by Benjamin Franklin to protect houses from very dangerous and destructive lightning strikes. The rod, at the top of the house, was connected to a wire that ran all the way to the ground. When lightning would strike, the electricity was harmlessly transferred into the ground. Though this invention may seem very simple, it was unheard of during the time that Benjamin Franklin introduced it. On the other hand, Franklin was thought to be way ahead of his time.
The Article “Finding Flow” by Mihaly Csikszentmihalyi, expresses the choice we have in life to live or die until the end of days. He shows how we take control of our own destiny, and to not let distractions get in the way of our accomplishment. Csikszentmihalyi portrays that everyone has a different idea of accomplishment and goals, but living life to the fullest is shared by many. By saying this he means don’t waste your potential by letting side issues get in the way. In the article Csikszentmihalyi mentions a study held in a factory where most welders hated their jobs and found no passion in it.
You need to create the project scope; how big the project will be and the deadline, budgeting, etc. You need to breakdown to the goals and milestone into task that would be completed. You need to identify constraints that restrict not just the project as a whole but the tasks themselves. You need to think of how many people should work on one task and if one task is related to another. 6.
1. Within a half hour there will be dramatic changes recorded almost instantly with a couple of seconds of grounding B. Magnets cannot provide any free electrons like the earth can also they can’t connect with the natural balancing. 1. But they do produce some therapeutic effects when they are properly
The tuning fork’s vibrations were directing along the length of the tube with its prongs lined up along it. The tube’s length was adjusted until the volume of the sound was at its highest amplitude. Then the length of the column was measured by its resonance. These steps were repeated for the other two tuning forks. The hypothesis was not supported because the highest frequency had the lowest length of the tube.
It will not only generate waves of positivity, but it will produce a radical alteration in our society (Achor,
