...**Physics** Introduction This paper seeks to answer a number of questions relating to physics.The areas covered include amount of wasted heat, average temperature of exhaust gas, design, amount of energy generated, and finally and estimation of the installation and maintenance costs, size, and weight of your design. 1. Estimate the amount of heat wasted on each mile from a typical car (30 MPG) Heat from any automobile is produced by burning of oxygen. The gas that is produced is carbon dioxide that is usually a product of combustion. Although there are other by-products of combustion, the main by-product is carbon dioxide (CO2). The heat that is produced will be calculated from the amount of carbon dioxide that is produced....

...? **Physics** The universe is so large and enormous that it cannot be explained in words nor can be imagined by any one. Our earth which feels and seems to us very large is in actual equivalent to a small dust particle in comparison to the enormous universe. Universe consists of a number of different elements. The universe comprises of millions of super clusters. These super clusters consist of hundreds of different sized galaxies. Of such a super cluster is our earth a part of. The super cluster consists of galaxies in the form of groups. The galaxy in which earth is situated is called Milky Way and is situated in a group called the local group which comprises of more than 30 galaxies (Caprara & Harris, 2003). The Milky Way is made... ...

...INTRODUCTION TO **PHYSICS** The word "**physics**" is derived from "physis" which means natural development. However **physics** is the science that studies therelation between matter and energy, thereby gives an integrated outlook to **physical** phenomena. Even as early as 16th century, the concept of **physics** inspired many great scientists like Galileo, Newton. But it gained an independent identity in 19th century. New discoveries constantly open new outlook for learning about nature. It is a way of looking at nature from the ground up, and has inspired the philosophies of the twentieth century. Today, the scope of **physics** is expanding through...

... 29 May 2007 Mathematics Prove the quadratic formula by completing the square. The quadratic equation has the solutions
To prove this, we will complete the square.
Consider the general quadratic equation
with a 0. First divide both sides of the equation by a to get
which leads to
Next complete the square by adding to both sides
Finally we take the square root of both sides:
or
We call this result the Quadratic Formula and normally write...

...**MATH** PORTFOLIO: CREATING A LOGISTIC MODEL A geometric population growth model takes the from where r is the growth factor and is the population at year n. For example, if the population were to increase annually by 20%, the growth factor is r = 1.2, and this would lead to an exponential growth. If r = 1 the population is stable. A logistic model takes a similar form to the geometric, but the growth factor depends on the size of the population and is variable. The growth factor is often estimated as a linear function by taking estimates of the projected initial growth rate and the eventual population limit.

...**Physics** (PART A) Question A particle moves with uniform speed v = 2.0 m s along a circular path of radius 5.0 m. Figure shows two points A and B on the circle. The angle subtended by the arc AB at the centre O is π/3 radians. Also shown are the velocity vectors of the particle, vA and vB, when it passes through A and B, respectively.
(a) Determine the length of arc from A to B and the time Δt taken for the particle to travel along this arc. (2 marks)
length of arc (S) = r · θ = 5.0 * (π / 3) = 5π/3 m. ≈ 5.24 m.
(b) Make a similar sketch and draw in the vector representing the change of velocity Δv = vB – vA. Use trigonometry to obtain the magnitude |Δv|. (Some useful construction lines are shown dashed in...

... Statistics Samples The interest is to determine whether the new program established to aid in improving the performance of students has an impact. As such, the sample score is 40 pairs of students. The first sample is the pretest where 40 students who are not involved in the program participate. The second sample is the posttest where 40 students are involved in the program participate. The relationship of these samples is that the pretest has corresponding posttest of the students.
Problem
The problem involves determination of the performance of the students in terms of scores. Thus, when each student (ith) score prior and after participation in the program is xi and yi respectively, it is clear that the pair (xi, yi) gives... Statistics...
