When a magnet is in motion near a non-magnetic conductor such as copper and aluminium eddy currents are induced in the conductor, causing a dissipative force called magnetic braking force, or a change in magnetic flux (figure 2). This force is dependent on: The size and shape of the conductor and magnet The strength of the magnet (μ) The conductors conductivity (σ_c) The distance between the conductive surface and the magnet (d) The velocity of the magnet (v) According to Faraday’s law,…
the example equation below: Atomic Absorption Calibration Data We were asked to prepare a 10 g/L HCl solution from a 200 g/L standard solution, and found the volume by: Thus, we add 5 mL of 200 g/L HCl to get 100 mL of our 10 g/L HCl solution.…
arguments that not only try to show the existence of life, but also the existence of communicative civilisations. Frank Drake formulated the Drake equation one of the most famous one of these models. Rather than evaluate and quantify the number of civilisations, the equation yearned to inspire scientific dialogue at SETI ( Search for Intelligent life). The equation shows that the number of civilisations - N - is a product of certain variables such as the number of Sun like stars older…
to come in contact or find proof? This lack of contact is sometimes referred to as “The Great Silence.” Many have tried to come up with solutions to this paradox and some of them definitely seem plausible. One of the obvious ones is that the Drake Equation is completely wrong. However, one of the bigger theories out there is known as “The Great…
Influenced through encounters with China and the West, the Japanese explored mathematical topics that were relevant to their time, which led to Japan’s shift from wasan (和算, Japanese Mathematics) to yôsan (洋算, Western Mathematics) in the Meiji era, and ultimately various technological advancements. As seen in Japan’s first encounters with the west, Sakoku (鎖国, the national seclusion policy) was the direct result of distrust of the Christian missionaries, which led to limited trade of ideas. In…
as the R² value is 0.9697. The hypothesis that the reaction would be first order was also supported, which can be seen in graph 2 of the results, where the natural log of the molarity was plotted against time and the trendline was linear, with the equation of ln(M) = 0.0016t + 0.1434. This is because…
functions, otherwise the equation will not be able to solve. An important rule to understand when deriving the quadratic formula by completing the square, is that the leading term must equal to “1”. On the other hand, if the leading term does not equal to “1”, one will have to factor the equation by dividing each term by the leading term. The quadratic equation must start as the following: 〖ax〗^2+bx+c=0. Next, the constant number is to be moved to the other side of the equation. Another…
It seemed like all the large questions had been answered. The behaviour of bodies, from asteroids to galaxies, was predicted by Sir Isaac Newton 's laws of gravity and motion. Magnetism, electricity and light were linked by James Clerk Maxwell’s Equations. The understanding of the atom had reached the plum pudding stage, where an atom was a globe of 'stuff ' with the positive and negative charges speckled throughout. Physicists were confident that all the important things had been discovered,…
points in Desmos, (2 toppings, 13.85) and (4 toppings, 16.99), both are medium pizzas. I asked students to get the price per topping which is the slope and subtract it two times from $13.85 to get the base price or the y-intercept. We tested the equation by opening the website of pizza hut. Students are able to compare the prices as well as qualities of the pizza stores. In this activity I was able to engage students in exploring real-world issues and solving authentic problems using digital…
CH 204 – Introduction to Chemical Practice Experiment 10 – Kinetics Joshua Fu* Tien Tran TA: Jamie Trindell April 25, 2016 INTRODUCTION This experiment focused on the concept of chemical kinetics, which describes the speed at which a chemical reaction occurs and the amount of reactant or product remaining after a specific period of time. Kinetics is important in analyzing the rates of certain species and reactions, and is a crucial technique to predict different reactions. Kinetics is…
