Most people imagine time as a constant. Physicist Albert Einstein illustrated that time is an illusion that it is relative which it can differ for different observers depending on the speed through space. To Einstein, time is a fourth dimension and space is described as a three-dimensional field, which provides a traveler with coordinates such as length, height and width showing location. Time provides one more coordinate direction although conventionally, it only moves forward. Time…
After four hundred years of its invention, it became an important scientific instrument, a symbol of science. All through the 400 years history, this invention changed our view of the universe, our thoughts, societies and even our thoughts. This incredible scientific instrument has been built by the famous astronomer and philosopher from Pisa, Galileo Galilei. This invention can make far objects appear closer when viewed through one end of its long pipe. It was a telescope. The telescope’s…
ROLE OF ELECTROMAGNETIC RADIATION AND BEER LAMBERT’S LAW Electromagnetic radiation Electromagnetic radiatio :– it is a form of energy whose behavior is described by the properties of particles and wave. Few properties of electromagnetic radiation for eg. Its refraction when it passes from one medium to another are explained best by describing light as a wave. Some other properties such as emission and absorption are better explained by treating light as a particle. The correct or exact nature…
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…
Core 1 Quantitative Assignment 1 Background: When wanting to find the mass of a massive object, the following is needed, Newton’s gravitational law (F = ma = mv2/r). Newton’s gravitational law can be used to calculate the mass which is represented by (M). This can be calculated if the velocity represented by (v), at orbital radius represented by (r), is known for the equation. When these two laws are put together they create the formula M = v2 r / G what G represents is the…
The Egg-Drop Device Process The process of dropping an egg is more complex than a normal person would believe. The egg-dropping process requires knowledge of history, engineering, and mathematics and physics. To fully understand how an egg drops, the knowledge of the history of physics, the engineering behind a device, and the mathematics and physics of free-fall is needed. Physics originates in its classical form in Ancient Greece. Thales was the first physicist. The theories Thales made gave…
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…
Molecular Orbital Theory (MOT): The VBT has two most serious limitations that electrons in molecules are treated as though they are localised and behave almost as they did in isolated atoms. This means that the VBT retains the individuality of the atoms composing molecule. The problem can be resolved by introducing the resonance theory, but with the loss of the original valence bond model. Hund[ 173], Mulliken[ 174], Van Vleck[175], Helsenberg[176], Jones[ 177] and others suggested an alternate…
The purpose of this lab is to evaluate the relationship between kinetic friction coefficient and static coefficient as well as measure the coefficients of the two friction. Friction is the force that resists relative tangential movement. Its direction is opposite to the relative velocity. Kinetic friction and static friction are two types of friction. Static Friction happens when the two surface in contact remains relatively stationary to each other. It reaches its maximum value before the…
Newton's Second Law: It describes what happens to the body when it is affected by force, as it shows the relationship between the force affecting the body, and the movement acquired by the body. Through the study of Newton's first law, we see that in the absence of an effective force on an object or the existence of a group of balanced forces affecting it, This body will be in a state of stillness or regular movement in the straight line. We continue to study the movement of objects when a force…
