1. Derive the mathematical expression for the Lorentz transformation equation. relative orientation of the co-ordinate systems indicated in fig.2 A light-signal, which is proceeding along the positive axis of x, is transmitted according to the equation : x - ct = 0 _______ (1). Since the same light-signal has to be transmitted relative to K1 with the velocity c, the propagation relative to the system K1 will be represented by the analogous formula x' - ct' = 0 _______(2) therefore:…

II. 2. Hydraulic Jump 2.2.1. purpose 1. to create/generate hydraulic jump 2. To clarify questions about the fluid flow. 3. To determine the slatrility and characteristics of hydraulic jump, performed in the laboratory using impulse momentum and energy equations are specific. 4. to compare between the depth of flow measurements and the results of the theory. 2.2.2. Basic Theory A hydraulic jump occurs when the flow of the flow at a high speed exposure at a low-speed flow that occurs at the…

When it comes down to it, nobody is perfect. We all make mistakes and learn from them to better ourselves and to better address situations at hand. There is always room for improvement and to prepare ourselves to deal with whatever may come to us in the future. This then leads me to organizational behavior and the ways to achieve the greatest possible outcome within groups, organizations, and as well as individual satisfaction. There are certain concepts to be considered in order for an…

In this experiment to configure the drink that has the most effect on teeth, the different drinks were placed in cup containing a hard boiled egg then weighed daily using a weighing scale. The results indicated that coke out of the seven other drinks had the most effect on the weight of the egg with acted as the teeth. If we look at the result as the days increased the weight of the egg and the drink decreased. The results were all constant except the raspberry cordial. The average of the…

The purpose of this research is to find a the relationship between performing leisure activities and the amount of perceived stress. Maintaining good physical and mental health through forms of self-care is important to managing stress effectively. The participants in this study were made up of 8 males and 21 females. The participants of this study were asked to fill out a survey asking about their stress levels and the frequency of listed activities they do leisurely per week. It was…

High school is often very stressful for students. Many high school students spend many hours working on homework in order to ingrain the material into their minds. Other students may do this but are still never able to absorb the information that they are given. As a result, when report cards are distributed, some of the students who have worked or have struggled to work hard have not been able to understand the classroom materials are stricken with fear upon seeing their bad grades. Bad grades…

Inelastic collisions occur when the kinetic energy of an object is not conserved, but converted into other forms of energy, such as heat or potential energy. As such, they still obey the conservation of energy principle that energy cannot be created or destroyed. When two bodies undergo an inelastic collision, their combined initial kinetic energy is not equal to the final kinetic energy of the system. When a tennis ball bounces on the ground, the kinetic energy that the ball possesses just…

1.1 Explain the typical axis conventions of the following machine tool in the form of a written report. Lathe Machine Tool Lathe machine is a machine tool that rotates the work piece on its axis to perform various operations such as cutting, sanding, knurling, drilling, or deformation, facing, turning, with tools that are applied to the work piece to create an object with symmetry about an axis of rotation. (n.d.) Typical axis conventions of the Lathe Machine tool • The work piece is…

Aim Simple Pendulum Experiment The aim of the experiment was to determine the effects of two factors (the length of a pendulum and the hanging mass of a pendulum) on the period of oscillation of the simple pendulum and to determine the value of g, the acceleration due to gravity. Apparatus Retort stand String Meter ruler Table Standard hex nuts (as suspended mass) Stopwatch Labelled Diagram Illustrating setup Method Experiment A: The simple pendulum was assembled using a retort stand,…

The Pocket Shot the Circular Slingshot A new take on the slingshot, a natural evolution, if you will, from the traditional slingshot to a circular one that you can carry in your pocket, tackle box, or backpack, closed it measures 2.3 inches by 1.3 inches, so carry it anywhere. It is described as a projectile launcher with a cone-shaped latex pouch that is securely attached to a fiber-reinforced composite ring, so all you do is drop your ammo into the pouch, stretch it back, and let fly.…
