Abstract Crucibles, Bunsen burners, a hot plate, and an evaporating dish were used to examine the reactions of magnesium and oxygen, zinc and hydrochloric acid, and the dehydration of Copper (II) sulfate. The results were MgO, ZnCl2, and CuSo4 + 5H2O. Introduction Individual elements are chemically combined to form new, complex compounds through synthesis reactions. Synthesis reactions follow the pattern...

Abstractâ Capturing photos in low light conditions is a difficult situation for photographers to get optimal image results. Low light conditions can occur at night, in the forest or in a dark room. The image quality in low light conditions is not good because the objects in the picture are lack of light which makes some objects blur and hard...

Abstract The 2003 Boumerdes earthquake occurred in the north of Algeria and caused significant amounts of damage in the cities of Boumerdes and Algiers. This study aims to simulate strong ground motion of the mainshock and aftershock of this earthquake by using empirical Greenâs function method (EGFM). The obtained source model of the main shock called strong motion generation areas...

Introduction Until the end of the 19th century, physics was able to expalin the mechanic, acoustic and thermal phenomena by Newtonâs Laws and electric, magnetic and optics by Maxwellâs Equations at the macroscopic scale. Even though these two great phenomena showed separation between wave-like behavior and corpuscular character of matter, some observations could not be explained by classical physics while...

Abstract Simple harmonic motion is the motion of a body travels back and forth over a fixed path, returning to each position and velocity after a certain interval of time. A simple pendulum definitely can be used to demonstrate simple harmonic motion. The objectives of this assignment are to investigate the relationship between length of the simple pendulum and the...

Real-time Computer-generated imagery (CGI) projects are taking off in the animation industry allowing bigger, better ideas and realistic motions. This allows animators to capture physical motion through a motion capture suit or tracking dots on the actorâs faces. Motion capture was first developed by Max Fleischer in 1915. The first full-length file that used it was Snow White and the...

In the following essay I will discuss reasons why I believe evaluating sound insulation of partition walls between two dwellings can be considered simple or indeed difficult. For extra clarity, I will describe a dwelling as a self-contained unit of accommodation used by one or more households as a home, such as a house, apartment or other 'substantial' structure; for...

One of Albert Einsteinâs most famous quotes is, âGod does not play dice with the universe.âBut there are two huge errors in the way many people have interpreted this quote over the years. People have wrongly assumed Einstein was religious, believed in destiny, or that he completely rejected a core theory in physics. First, Einstein wasnât referring to a personal...

Syllogism Companies that do not recycle, increase contamination levels. Those who increase contamination levels should be involved in environmental protection activity. Companies that do not recycle should be involved in environmental protection activities. Introduction Recycling is generally regarded as an important and inevitable part of environmental protection, as well as the saving of natural resources. The constantly increasing population of...

We often have preconceptions of how things should sound, as we hear them in day to day life without even taking notice of every single sound. But what is sound design? It can provoke a mood or feeling, and it can also inform the gamer with information such as doing a task with an audio prompt, or locating important clues...

Quantum mechanics has been controversial since its birth, and its abstract, uncertain nature makes it hard for the public to understand. However, with the development of science, more and more quantum theories and interesting facts has been discovered. Some of the theories have already been applied to many fields such as the quantum computer. The purpose of this essay is...

Cavity wall insulation is method used to reduce heat loss through the walls filling the air space with material that inhibits heat transfer. Cavity walls are constructed in houses. It is an outside wall and an inside wall with a space between the two walls which is air. This is known to be an effective way preventing of the wall...

The idea behind quantum computing is to resolve problems in various domains of mathematics, physics, chemistry etc. They are mainly deployed to perform operations that are super complex in nature and are beyond the computing of conventional computers. They basically work with the technology of qubits in which the control signals are operated upon. The qubits are represented using Bloch...

This pendulum labâs objective is to describe how the back-and-forth motion of a pendulum can be changed through measuring the properties of a pendulum, as well as determine which properties of a pendulum affects its period. Groups of generally four students created their own pendulum, all materials provided in the classroom, and each group tested how three different properties affect...

In this experiment, our aim is to determine the unknown tension by using the components of the force vectors in equilibrium. Method First, we place a ring with three strings over the center (reference point), and set up the three pulleys. We will have two known masses which are 50 g each hanged from two strings which can be changed...

Introduction Density Functional Theory (DFT) stands as a cornerstone in the realm of quantum mechanics, offering valuable insights into the electronic structure of matter. Since its inception in the mid-20th century, DFT has revolutionized computational chemistry and materials science by providing a practical framework to study complex systems. At its core, DFT transforms the many-body problem of interacting electrons into...

Human beings have been trying to understand how light works since the time of the Ancient Greeks. In roughly 300 BC Euclid studied the properties of light, he thought light travelled in straight lines and described the laws of reflection. In 1690 Sir Isaac Newton came out with the corpuscular theory of light, he believed that light was shot out...

There is this unpopular opinion that everything is unique. Even the things we think are the most alike, still have some sort of variation in them. Take identical twins for instance; science made us to understand that there is no identical twin that are 100% the same. That is talking about their DNA compositions. The keyword here is âdifferenceâ. What...

Physics is the study of how the universe works, it lays the foundation for the description of the cause and effect objects have on one another. The consequences forces have upon impact with objects lay the foundation for the interaction of forces in the physical world. Forces are vector quantities they carry a magnitude as well as a direction, when...

In 1909, Ernest Rutherford discovered that the bulk of the atomic magnitude was tightly condensed into a nucleus, which was establish to be positively charged. It became clear from his assay in 1911 that the coveted pudding example may possibly not account for atomic structure. In 1913 as Rutherford's post-doctoral student, Neilâs Bohr planned a new form of the atom,...
