HIGH-VELOCITY INJURIES Harland Hayes‚ University of Utah School of Medicine It should be no great surprise to find out that the most serious of injuries that occur in the back country are those that are associated when people are moving with speed. There are common sports that by their very nature require speed such as skiing where injuries don’t have to occur. However‚ there are other sports that demand deliberate even delicate moves‚ such as rock climbing‚ where speed gained from a fall

1) A 4-kg mass moving with speed 2 m/s‚ and a 2-kg mass moving with a speed of 4 m/s‚ are gliding over a horizontal frictionless surface. Both objects encounter the same horizontal force‚ which directly opposes their motion‚ and are brought to rest by it. Which statement best describes their respective stopping distances? (A) The 4-kg mass travels twice as far as the 2-kg mass before stopping. (B) The 2-kg mass travels twice as far as the 4-kg mass before stopping. (C) Both masses travel the

In the article‚ “Lagging Far Behind: Women in the Middle East” Judith Colp Rubin (2012)‚ an author‚ journalist and publisher‚ demonstrates the main aspects behind causing inequality between male and female rights in the Arab World. Colp Rubin clearly states based on certified statistical evidence‚ that despite of the basic rights given to females in the Arab region‚ lack in the equilibrium between both genders has still been consistent. She demonstrates her claim by referring to the discriminated

ours‚ our findings can hardly pale into insignificance as errors and the cause of uncertainty are discussed and ways to improve the experiment are suggested‚ which can possibly spur further studies on this realm of knowledge. I. Introduction In physics‚ there are mainly two ways from which useful equations can be derived. One from them is to make good use of the mathematical expression of the theories formulated by our predecessors. An archetype to this notion is the Newton’s second law‚ which states

The Physics of an MRI Machine. Whitney Wright PH106/006 Dr. Probst 06/05/2012 The Physics of an MRI Machine There are many physical concepts used in a Magnetic Resonance Imaging‚ also known as MRI‚ machine. There are many physical concepts used when an MRI is taken of the body‚ such as; radio waves‚ resonance and pulse sequences‚ magnetic fields being produced and lastly‚ magnets. Radio waves much stronger than the magnetic field of the Earth are sent through

application of physics’ principles such as momentum‚ friction‚ gravity‚ and even momentum. Momentum is a vector quantity‚ meaning that it needs a magnitude and direction‚ and this expression is mathematically defined as p=mv. The momentum is equal to the mass times velocity. In wrestling‚ two colliding wrestlers are subject to a change in momentum. For instance‚ a wrestler will attempt to apply an impulsive force north for as long as possible and as

Physics 2 Application to IT and daily living! Thermal Physics Thermal physics the study of temperature‚ heat‚ and how they affect matter. I can apply this in determining how hot or cold the object. Though I have my senses in concluding the temperature of an object‚ they are unreliable and often misleading. Ex. A metal and a stone that is both expose to sun. I can conclude; base on what I’d learned that the metal is hotter than the stone. Putting a metal spoon in a cooking soup. To make

ULTRASOUND PHYSICS Name Institution a) Calculate the Acoustic impedance of subcutaneous tissue‚ muscle and bone. Assume subcutaneous tissue has a density of 1060kg/m3 (Hedrick 2003)‚ muscle has a density of 1104kg/m3 (Madjor 2008) and bone has a density of 5065kg/m3 (Hedrick 2003). Give your answer in Mrayls. Please use speed of sound as 1540m/s for tissue‚ muscle and bone In ultrasound‚ Acoustic impedance (Z) is the quantity of measurement of resistance to sound when passing through a medium

The K to 12 program‚ it introduces a new curriculum in which has adopted the twelve (12) year United States ’ educational system. The people and students have mixed reaction to the program. Some said it is a good way to end the problems of education. Some said it will be another burden to parents
