Physics of a Light Bulb Catherine Bellet Lab Partners: Natalie Russell Alex Harris TA: Chad Lunceford PHY 114 TH @ 2:25pm Abstract: Ohm’s law states‚ via the equation V=I*R‚ that the voltage found across a piece of material is proportional to the current. If the temperature remains constant therefore the resistance is found to remain constant. Stefan-Boltzmann law states that when the temperature if above an average of 1000K‚ then the relationship of voltage and current should be found

I have lived in NYC for 10 years. The first five years I spent getting my MFA in film at Columbia University and making my award winning thesis film‚ Loop Planes‚ which was produced by Killer Films and was an official selection at over 50 film festivals world-wide. The second five years I spent filming a documentary about young transgender folks‚ which besides being an integral part of the development of young teenagers to young adults… During that time I have also worked on over 100 short films

Question 1(10 marks) Comment the following statements (a) The volume coefficient of thermal expansion of water is negative for temperatures in the range 0 to 4 °C. (b) The triple point of water‚ 0.01 °C‚ and 611.73 Pa‚ is one of the primary fixed points on the Kelvin absolute temperature scale. (c) The volume coefficient for the thermal expansion of a solid is twice the linear coefficient for thermal expansion. (d) A temperature of 26.85 °C is the same as 300 K. (e) The surface temperature

rely on Earth’s gravity to get the cars down the track? Roller coasters are centered all on physics and I will hopefully teach you some things‚ big or small about them today. In this essay we will be exploring the world of roller coasters. Some of the topics we will cover will range from the history‚ to the principles that allow the cars to continue throughout the length of the track‚ and the general physics surrounding roller coasters. The history of roller coasters is a very interesting and long

3. Recent technological developments have allowed greater use of the electromagnetic spectrum 1. describe electromagnetic waves in terms of their speed in space and their lack of requirement of a medium for propagation In space (a vacuum) electromagnetic waves travel at the speed of light‚ a constant equal to 3.00108ms1. Unlike sound waves‚ electromagnetic waves do not vibrate particles‚ therefore they do not need a medium (substance) to propagate (move). 2. identify the electromagnetic wavebands

Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist‚ and the first Greek philosopher

thrill all comes from the acceleration and the feeling of weightlessness that they produce. Roller coasters thrill people because of their ability to accelerate them downward one moment and upwards the next; leftwards one moment and rightwards the next. How does this thrill machine work? There are two ways that this question will be answered. First‚ through the basic principles and then through a more advanced explanation. Roller coaster rides involve a great deal of physics. The ride often begins with

In Newtonian physics‚ free fall is any motion of a body where its weight is the only force acting upon it. In the context of general relativity‚ where gravitation is reduced to a space-time curvature‚ a body in free fall has no force acting on it and it moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain. An object in the technical sense of free fall may not necessarily be falling down in the usual sense of the term. An object moving upwards
