Physics can often explain many of the everyday activities of life; from playing football to ice skating to visiting an amusement park. Most people step into an amusement park excited for the thrill of riding all of the roller coasters without ever giving any thought to the physics behind the ride. There are several components of physics which contribute to the thrill of roller coasters, including gravitational forces, the law of conservation of energy, friction, centripetal force, and normal…

An electron vacancy is created and is further filled by an electron from the higher shell and thus an X-ray is emitted to balance the difference in energy between the two electrons. The detector placed on the energy dispersive spectroscope apparatus measures the number of emitted X-rays and their energies. Energy of the X-ray is characteristics of the element from which X-ray is emitted. A spectrum of the relative counts of the detected X-rays is obtained and evaluated for quantitative…

1. How do you adjust the pulling force of the mousetrap? Adjusting the length of the snapper will change the pulling force—making something move as it goes in a certain direction. Making the snapper on the mousetrap longer will decrease the pulling force and a shorter snapper will increase it.…

Results and dissection 3.1 Transition metal complexes of the macrocyclic, H6L Ligand 3.1.1 The macrocyclic, H6L Ligand The physical and analytical data of the macrocyclic, H6L ligand and its transition metal complexes were shown in Table 1. From the investigation, the expected structure of H6L with its possible toutomeric forms can be represented as shown in Figure 1. H6L ligand is highly symmetric under the point group C2v symmetry and can show all the normal modes of vibrations by solving…

1. The following events related to untochable force: (1) coconuts falling from the tree to the ground (2) Attract magnetic iron plates (3) footwear be worn after long use (4) Budi push the beam to shift to the right The above events involving untouchable force is the number of events .... a. 1 and 2 b. 1 and 3 c. 2 and 4 d. 4 2. Amir and Badu are playing tug of war. Amir pull to the left with a force of 200 N while Badu pull to the right by the force of 350 N. resultant force generated is ....…

INTRODUCTION • Energy is a scalar quantity. • It was first hypothesized by Newton to express kinetic and potential energies. • We cannot observe energy directly, but we can measure it using indirect methods and analyze its value. • Energy may be in different forms, such as potential, kinetic, magnetic or electrical. Potential energy of a system is by virtue of its location with respect to gravitational field. If an object has a mass m, located at elevation h, and acceleration due to gravity is g…

Pierre Bourdieu was born on 1 August 1930 in Denguin, France. He attained a degree in philosophy and was also the gold medalist of the National Centre for Scientific Research. Throughout his life, he contributed to various areas of discussions and involvements that include art and culture, education, language and methodology (Grenfell 2012:12-14). Bourdieu was also influenced by Karl Marx and adapted his theories to elaborate further on capital in regards to class divisions. Similar to Marx,…

J.J Thomson was born in Cheetham Hill, a suburban area in Manchester, England on December 18, 1856. Thomson was a Nobel Prize winning physicist with his research that helped discover the electrons of an atom. J.J Thomson full name was Joseph John Thomson, He was an English physicist and mathematician. Joseph Thomson was considered to be a prodigy at his time, becoming the first to be 14 and attending college. Joseph Thomson’s father was a book seller who intended Thomson to become an engineer.…

Stress: Stress is defined as ‘’the force across a boundary per unit area, for all orientations of that boundary.’’ It is derived from force, a physical quantity and area, a geometrical quantity. Therefore, stress is also characterized as a fundamental quantity, like velocity, energy, etc. that can be brought under quantification and can be analyzed without any obvious attention of the physical grounds of the material or of its nature. Example: When a solid bar is supporting a load, each…

1. The pendulum of a clock swings back and forth. At what position will its kinetic energy be the greatest? At what position will its kinetic energy equal its potential energy? When the pendulum of a clock swings back and forth, the pendulum reaches its maximum potential energy at the top of the swing, and it reaches its maximum kinetic energy at the bottom of the swing. In the absence of frictional forces, the pendulum’s kinetic energy will be equal to its potential energy at the bottom of the…
