Which type of surface will produce the fastest race time? Concrete‚ sandpaper‚ or gravel? If I race a remote control truck on a concrete‚ sandpaper‚ and gravel surface‚ I think the truck will go faster on the concrete surface. 1. Gather all of your materials. 2. Using your measuring tape‚ measure 12 ft in distance from the starting point to the finish line. Make sure your area is flat and dry. 3. Stick pieces of tape at the beginning and end of your track to form a clear

then determined that there were four ways to increase the reaction rate: increase temperature‚ add a catalyst‚ increase surface area‚ and increase the concentration of reactants. The objective of this lab was to experimentally show how temperature and surface area impact the rate of reaction‚ so only two of these methods were tested. The evidence indicates that increasing surface area increases the reaction rate‚ and increasing temperature also increases the reaction rate. Temperature is the measure

diffusion. Diffusion is the process that cells use to obtain oxygen‚ water and food. Also‚ how they lose waste substances‚ for example‚ urea and carbon dioxide. Basically‚ Diffusion is when particles move from an area of high concentration to an area of low concentration. The surface area to volume ratio of the cell is an important factor in diffusion. It is the effect of this factor that will be investigated in this practical. Materials used in the practical consist of blocks of agar jelly containing

Lab 7 Wide Area Networks 7.1 Distance Consideration 7.1.1 A WAN is a wide area network that is often used by large businesses or corporations. It is impractical for an organization to own an entirety of a WAN because a WAN is decentralized It’s l for an organization to own an entire LAN‚ or local area network‚ for business expansion purposes. This is control over a dedicated section of the local network that other businesses will want to buy into. 7.1.2 Increasing the required transmission distance

Topic Selection Microsoft recently unveiled its prototype‚ Surface‚ their version of a tablet or alternative device to a personal computer. It is questionable how Microsoft‚ a known software company‚ will be able to manufacture and sell a tablet device that is a contender in the marketplace against devices such as the iPad. Thesis: It is critical that Microsoft produce a device that overcomes the limitations of its competitors and adds features that set it apart‚ in order to define itself in

transmission. Direct transmission occurs when there is physical contact between an infected person and a susceptible person. Indirect contact transmission occurs when there is no direct human-to-human contact. Contact occurs from a reservoir to contaminated surfaces or objects‚ or to vectors such as insects or animals. Direct contact infections spread when microorganisms pass from the infected person to the healthy person via direct physical contact with blood or body fluids. Examples of direct contact are touching
