    coating against alumina ball. High run-in friction values of ~ 0.153 (average) were observed with the MCD coatings. The high run-in friction behavior of the MCD coating as compared to the NCD and BDNCD coatings was attributed to its sharp and rough surface asperities. When increasing the time, at a sliding speed of 8 m/s and a load of 10 N, the friction coefficient first increases and then decreases gradually after a time period of 5 minutes and remains constant after 12 minutes. The NCD, MCD…

    same as the pressure of the atmosphere on the liquid surface”. (Mahaffy, P, Bucat, B, Tasker, R, Kotz, J, Treichel, P, Weaver, G, McMurry, J 2011). The boiling point 1-hexanol, 2-hexanone, 1-pentanol and 3-methyl-1-butanol are represented in the chart above as they are approximately; 157ºC, 127.6ºC , between 137 to 139ºC and 131.1ºC respectively. The difference in the general trends of the molecules affects on the boiling point; the molecular surface area of the compound influence by the…

    has no water there is no erosion so it's surface is not constantly changing like the earth. Tectonic forces are also not active on the moon so volcanic eruptions don't happen. Since the moon is not protected by an atmosphere different types of erosion occur. Small space particles are constantly hitting the moon's surface and overtime is creates a smoothing effect on the moon's surface. The moon's rocks become rounded top as result of being at the lunar surface, still the moon most likely hasn't…

    spirit of Hellix, and the Solar Blade. This planet had a red-brown tint to its ground, covered in Ignis Redstone powder, the most flammable substance in the universe. The ground was completely rugged, with cracks all over the surface. The spirit of Hellix was spawned onto the surface of the giant planet, holding the Solar Blade. Hellix made his long embarkment to the center of the planet, where stood the Flammaki, a large bump with a hole in the center to fit the Solar Blade perfectly. Hellix…

    Discovered in 1930, by the American astronomer Clyde Tombaugh, Pluto was thought to be the farthest, newest and smallest known planet in our solar system. Pluto, for 75 years would be thought of as the ninth planet in our solar system. It wasn’t until the discovery of Eris in 2005 that astronomers began to question what defines a planet. After the discovery of Eris and other celestial objects such as MakeMake, Pluto along these new discoveries have been defined as dwarf planets. They are…

    Static Friction Lab Report

    • 5 Pages

    Several factors impact the amounts of friction, and this experiment examines the factors and how they impact the sliding of the wooden blocks. Surface area of the blocks affect the friction, and the contact between the different surfaces varies for different objects and weights. Kinetic friction occurs when two objects move against each other with their surfaces in contact, and the normal force helps calculate kinetic friction. Static friction is the force which must be overcoming to originally…

    the raise in temperature of Earth’s surface, caused by the gases carbon dioxide, methane, dinitrogen and chlorofluorocarbons. For contrast, oxygen and nitrogen are gases that will not trap heat and are therefore not greenhouse gases. These greenhouse gases trap heat in the atmosphere. You see, the sun provides energy in the form of solar radiation; some of the radiation is reflected back into space, what is not is then absorbed by the clouds, the Earth’s surface and the atmospheric gases. As the…

    Southwest Research Institute working on NASA’s New Horizons, goes over an interesting discovery made about Pluto: It seems to have a near infinite supply of nitrogen. Pluto is Gassy The most recent images returned by New Horizons shows that Pluto’s surface is mostly composed of nitrogen, just like Earth’s. There is; however, about a 20 percent difference in composition; Earth’s atmosphere is around ~78 percent nitrogen while Pluto’s is ~98 percent. Another interesting fact is that the…

    The Greenhouse Effect - What is the greenhouse effect and why is it important? “The greenhouse gases absorb some of this energy and radiate much of it back towards the surface whilst the rest is radiated out to space. This plays an important role in keeping the Earth 's surface warm and able to sustain life.” Step 1: How much energy from the sun hits the earth and what determines the amount? Based on the energy coming in, what should be the average intensity of the energy leaving the earth? The…

    The cephalic vein which is located at the cranial aspect of the foreleg is a peripheral vein that is often used for venepuncture. This vein is often used as it is close to the surface of the skin and easily accessible (McCurnin and Bassert, (2002)).Before taking the blood sample, the dog is placed in sternal recumbancy or standing position and the area over where the needle is going to be inserted is shaved. If the dog is very small, it may need to be restrained in the owners arms and the…
