possible 334 points. The teacher will divide the number of points earned, 299, by the total possible points, 334, with the answer of 0.895. The teacher then multiplied this answer by 100 creating the number 89.5. This number is able to be rounded to the nearest ten percent, 90%. The student achieved the qualification for a grade of A. The student would not be given the grade of A if the teacher truncates the whole number. Truncating the number to the nearest whole, would leave the student…

Energy Equation, (3) Where u and v are velocity component along the x and y directions of a Cartesian coordinate system respectively, t is the time, p is the pressure, Re (= ρU∞d/μ) is the Reynolds number, Pr (= μCp/k) is the Prandtl number, T is the temperature, d is the diameter of cylinder, k is the thermal conductivity of fluid, Cp is the heat capacity of fluid, ρ is the density of fluid, μ is the dynamic viscosity of fluid and U∞ is the free stream velocity of…

In the reading, Phil Tiemeyer, gives a unique spin off of the telltale story of the infamous Gaëton Dugas. A man who could arguably be called the Hitler of the AIDS epidemic. In fact, not only does Tiemeyer say that the things people have learned about Mr. Dugas was a fabricated myth, but he also defends Dugas, by saying he could not have even been patient zero. An audacious claim to make about the villain of the late 20th century, however, surprisingly Tiemeyer does not speak without compelling…

protocol. Thus varied uses of these sensors leads to the fragmentation of the market where these sensors find their application in Parameter measurements such as temperature, pressure, strain, vibration, acceleration, pH level determination, refractive index of liquid etc. Fiber optic sensors because of their distinctive features also facilitate industries such as aerospace, medical, oil pipelining, transportation etc. Presently there has been some success in the sensor technology which are…

How much it bends depends on the refractive indices of the two mediums which is a ratio of the speed of light in one medium compared with the second. For example the refractive index (n) of crown glass can be calculated as it passes from air into crown glass Total internal reflection occurs when the refractive index of the first medium is more than that of the second. The angle of incidence is the angle that a ray of light hits an interface between two mediums relative to the normal. As…

title>INTRODUCTION Optical constants (complex refractive index n, complex dielectric function ϵ, and reflection and absorption coefficients R and α) of materials are of great importance for optical metrology in the semiconductor industry.1,2 A high-performance complementary-metal-oxide-semiconductor process flow with 11 layers of metal requires about 75 photolayers and may contain up to 100 thickness measurements, most of them performed using spectroscopic ellipsometry.3 This technique has…

“Free throws win games,” a phrase that athletes repeatedly hear from their basketball coaches. Even though free throws only count for a point, they tend to occur at the most critical parts of the game. Imagine, only a few seconds remain, and your team is losing by one point. Two simple free throws dictate which way the game swings. If you miss them both, your team loses. Make only one, and the game goes into overtime. Make them both, and you become the hero for your team. Thus, free throws win…

State Park, we determine the relative density, frequency, relative frequency, relative dominance and important value. <Table 1> is Ramapo Valley Reservation Park’s table . <Table 2> is Harriman State Park’s table. Relative density is percentage of number of individual of one species by sum of the individuals of all species. Relative frequency is percentage of frequency by sum of the frequencies of all species. Relative dominance is percentage of total basal area of one species by…

Different parts of the world have different political regimes and not many succeed in achieving being called a democratic state. In 2016 democracy is the political regime that the most powerful countries in the world follow. The list includes Norway, U.S.A, Germany and Sweden. Progressively, many countries are working on becoming a democracy. Some are being more prosperous, others struggle. It is not exactly easy to become a democratic country due to many requirements to fit the qualification.…
