Speed limits are placed everywhere amongst roads to secure each drivers safety. Near schools‚ school zones speed limits are placed‚ and active during the times that the school is open. These school zone speed limits are extended within a mile away from the school. Speed limits are much lower than average speed limits‚ so the children going and coming from school are safe. Once you go over the speed limit provided in a school zone‚ you put a child’s life in danger. During school hours many children

The speed of light is a well-established premise in physics. Centuries before‚ it was often heard by scientists like Johannes Kepler and Rene Descartes that the speed of light was infinite‚ having the ability to travel at any distance immediately. A notable physicist named Galileo Galilei was one of the first scientists to ponder this phenomenon of light‚ and how to determine the speed of this unknown. In order to do so‚ Galilei formulates an experiment with an assistant. While standing on one hilltop

Need for Speed: Nascar vs. Formula One. Nascar (National Association for Stock Car Racing) is a world apart from Formula One. Both are exceedingly popular‚ yet they lie at diverse ends of the motor sports spectrum. Most people who have an obsession with cars and racing may know about Nascar and Formula One‚ the two most respected names in motorsports today. At first glance‚ Nascar and Formula One seem very similar; however‚ a closer look reveals

Does concentration affect the speed of chemical reactions? Problem: We are proving that “concentration” (the amount of reactants) is one of the things that can affect the speed of chemical reactions. We are also finding a way to keep the lid on the film canister for the longest period of time. We are using vinegar and water as reactants and changing the concentration every time to see the difference between the rates of reactions speed. Materials: - 1 graduated cylinder - 1 film canister

All the twenty nine weather stations are distributed quite evenly in the entire kingdom. A spatial interpolation technique is used to predict the wind speed between the weather stations‚ where direct measured data is not available. In this analysis‚ the method used to convert the point data into raster format is the inverse distance weighted‚ IDW. It determines cell values using a linearly weighted combination of a set of sample points. The weight is a function of inverse distance. The surface being

Research An object that is falling through the atmosphere is subjected to two external forces. The first force is the gravitational force‚ expressed as the weight of the object. The weight equation which is weight (W) = mass (M) x gravitational acceleration (A) which is 9.8 meters per square second on the surface of the earth. The gravitational acceleration decreases with the square of the distance from the center of the earth. If the object were falling in a vacuum‚ this would be

Antebellum Reform Speed Dating: Horace Mann Horace Mann was a distinguished reformer for the education system for the public; he stated “ignorance is a crime” in hopes of remodeling the education system that was present. Being a son of a poor farmer‚ education was hard to find in his early life but became a determined student and soon advanced to studying law at the Litchfield Law School. He entered the Massachusetts House of Rep. in 1827 then moved onto state Senate in 1833. While being on legislation

Burn‚ Baby‚ Burn: Comparing the burning speed of scented and unscented candles This experiment was performed to compare how quickly a scented and an unscented candle will burn. The tests were done by comparing the length that the candles will burn in 30 minutes - using unscented‚ rose scented and apple scented candles. Hypothesis: Unscented candles burn more quickly than scented candles. Overview: Candles Candles are a convenient way of providing light and heat when no electricity is available
