hypotheses, pieces come out and in the end form the planets. However, in the Planetesimal hypothesis, the Sun is disturbed by a passing star and that never happens in the Nebular hypothesis. Also, the Nebular hypothesis uses the Law of Conservation of Angular Movement and the Planetesimal does…

pitch and its spin rate, and velocity of any ball thrown on the field. Exercise Science has increased the amount of measurements that can be taken in a wide range of areas, like the mobility of the shoulder, force and momentum produced from the lower body during the pitching motion, angular acceleration and torque of the trunk during the motions of pitching and batting, and even the measurements of muscles, especially those of the rotator cuff, responsible for stability of the shoulder joint. As…

Review of literture Intoduction to Firenadoes What is a firenado you might ask? Well a firenado isn’t really a tornado at all, all though they may seem similar. m.livescience.com says,” A true tornado is formed when three key elements collide: warm, moist air close to the ground; atmospheric instability, a condition that promotes the vertical movement of air; and clashing air fronts that act to propel moist air upward”. A tornado is a violent storm that strikes as a powerful rotating mixture of…

the same procedure was repeated. Exp #3 a. The fan speed was set to give an air velocity of 1 m/s while the voltage was set at 20 V. b. Angular position, Ua, T9, T10, V and I were recorded by rotating the cylinder by 30 degree if the temperatures reach the steady state condition. c. The cylinder was rotated by 30 degree until it reached 180 degree and Angular position; Ua, T9, T10, V and I were recorded at each angle. d. Finally, the fan was adjusted to give an air velocity of 5m/s and the…

2 Loads and Structural Stress Because of the energy content of the wind is relative to the cube of the wind speed, turbine blades exposed to wind speeds will be under an enormous amount of stress. In order to diminish the impact of wind speeds, turbine manufacturers develop the rotors on them with few blades somehow they are as narrow and long as practical (Pinting ZHANG and Shuhong HUANG 2011). The maximum efficiency from such blades can be attained based on the pitch at an optimum angle…

Spectroscopy is the study of objects, which is represented on the spectrum of color they radiate. An interaction of electromagnetic radiation with matter. Spectroscopy involves the process of absorption, emission, or scattering of electromagnetic radiation by either ions, atoms, or molecules. The process of absorption involves when light is absorbed by electrons that jump to higher energy levels. On the other hand, emission spectra are established when the electrons from high energy levels give…

Albert Einstein introduced his theory of General Relativity in 1915 (New Site). This theory includes a field equation for gravity, which consists of three terms: two tensors that represent space-time and the energy-momentum tensor. The energy momentum tensor represents the matter and energy in the universe which bends space-time to produce gravity (lecture 1). His equation is seen in Figure 1. Figure 1 On the right side of the equation is the matter and energy tensor and, on the left, are…

At Middle Tennessee State University student looking to pursue a forensic science major is required to earn 120 credit hours to graduate with a forensic science degree. According to the Forensic Science Academic Map, found in the Forensic science section on the MTSU website, as a freshman, a student must earn 29 credit hours of Expository Writing and Research and Argumentative Writing which focus on a variety of analytical writing and utilizing resources for the purpose of research. General…

When the high jumper takes off from his approach run he exerts a force to change direction (Coach.org, 2015). The Law of Acceleration asserts that, “the change in momentum of a body is proportional to the force that acts on the body, and takes place in the direction of that external force” (de Gosson, 2001). More force means greater acceleration. The more force the high jumper exerts at takeoff the greater the acceleration…

Photoacoustic spectroscopy (PAS) is a tool to study thermal emission resulting from non-radiative relaxation followed by absorption of radiation. PAS was studied primarily by Alexander Graham Bell, John Tyndall, Wilhelm Rontgen and Lord Rayleigh in 1884. For the history of PAS, was not until 1975 that photoacoustic spectroscopy started to be used as a wide range of different applications. This technique provides the following main advantages over the known types of spectroscopy. The advantages…
