Physics Essays

Swaying of buildings as a result of various effects of forces such as wind or earthquake is a form of simple harmonic motion. The amplitude of vibrations decreases with an increase in the loss of energy. This energy loss is mainly due to the friction between the bodies that are oscillating and air particles.

For any vibration to occur, a restoring force must be in existence. In this respect, a restoring force is identified in a pendulum. The restoring force is applied by the springs as long as Hooke’s law is observed. The restoring force, therefore, is

The filtering characteristic of polarizers enables them to isolate beams of mixed or non-defines wavelengths to beams of light bearing specific wavelengths. Among the primary application of polarizers include LCDs and optical instruments. Besides light beaming to specific wavelengths, polarizers also find other uses for electromagnetic waves such as X-rays and microwaves.

The acceleration units are the velocity over the time taken. Some of the fundamental illustrations are m/s2 and km/h. Acceleration is termed as a vector quantity. This is because it has a direction of final velocity minus the initial velocity. It is therefore, nonetheless to talk of the acceleration magnitude as acceleration only if there is no ambiguity.

He descended with a parachute recording the greatest free fall velocity in history of skydiving. This case study brings us to the physics discussion of free fall and the factors involved (Heitzmann,

A special sense that the principle has attracted for its application is power generation. The theoretical aspects are presented immediately after the introduction statement with mathematical evidence. An elaboration on the derivation

It is always regarded as coherent and simple, but it assumes creativity, human agency, and evolution. The constituent of the Newtonian ontology are the absolute space, matter, and time in that matter moves finally natural laws or the forces that control movement.

It is very critical to capture impression evidence images in crime scene investigations. For instance, shoe impressions, tire tracks, fingerprints, bloodstains, and many more are captured (Houck, and Siegel, 2010). For a criminal investigation to be efficient it depends entirely on the collection and analysis of different evidence and information collected.

Following this, the amplification of the signal is then resent to the input where it undergoes amplification once more. This process takes place repeatedly, thereby producing an amplified sound from a speaker (Ellinger, 78). Feedback entails this process of sending a section of the output of an amplifier back to the amplifier input.

Considering the circuit as shown above, the capacitor has no charge. When the switch is closed, electrons will flow beginning from the negative battery terminal and flows to the lower plate. Lower plate is made negative and charge is well

Specific heat capacity is the ratio between the heat capacity and the unit mass of a substance {C= Q/(mΔT)}, therefore the specific heat capacity of any substance is dependent on the

The author states that huge energy level needed to come up with a fully risen sea and the gradual decrease of wave height after a storm due to inertia are two reasons why wave-induced turbulence varies over much longer time periods. A breaking wave in coastal regions can lead to an increase of up to 10dB in deep water predictions.

Fresnel lens capture light from its source enhancing its visibility to considerable distances (Miller & Agnes, 2). In comparison to the conventional lenses, the Fresnel lens is much lighter as it reduces the amount of material required. Nowadays, the lens is made of plastic in a bid to reduce its manufacturing cost and its general weight.

A clamped metal rod was stroked in a lateral manner so as to produce energy and friction in form of the longitudinal wave. On entering the tube, the wave agitates the dust within and hence forming visible shapes. Measurements were then

Also, rainfalls experienced across the financial period varies, but approximately around 1800 milliliters. It has an extensive range of biodiversity and around 60% of nearly all

Stall occurs when the angle of attack (angle between the wing’s mean chord and the relative wind, parallel to the flight path, or the wind moving past the airfoil as the airfoil moves through the air) exceeds the wing’s ability to produce lift as a result of turbulent airflow over the wings. The low-pressure area above the wing reduces causing the inability to lift. One can encounter a stall at any airspeed, any altitude and any amount of throttle.

Oil and gas are extracted from the star sands using traditional pit mining method on the surface and in-situ production method, underground (“exploration and extraction of star sand” 6) Due to the advanced and costly techniques

The study was a success. Algebraically was found to be 0.252N at an angle of 56.3 degrees. The theoretical value of is zero. Physical quantities can either be vectors or scalar. Scalar quantities are represented by only their magnitude while both

According to the Bigert and Bergston study, the concern to improve the social welfare of people has challenged scientists to focus their attention in the creation of different types of tools in order to

Energy and kinematic equations should give the relationship between the variables under study. Data obtained from empirical procedures are not 100% accurate. Experimental errors account for the deviation between theoretical values and empirical data. After completion of a physics experiment, it is appropriate to carry out an error analysis exercise

A comparison of the kinetic and static friction shows that at the very first instance of pulling on the force sensor, the block did not move. This is because the force applied does not overcome the static friction force acting on the block. It reaches a force that overcomes the static friction force causing the block to begin to move.

The standard model makes predictions about the existence of particles to explain discrepancies in the observed characteristics of these observed particles and forces and the Standard Model, and more recent experiments with the Large Hadron Collider has given weight to the

In this lab investigation of whether the energy is conserved for different systems was performed. Three mechanical systems were used together with computer LoggerPro software Mechanical systems used were, a swinging pendulum,

Besides giant amoebas, called xenophyophores, other forms of life have managed to adapt to such extreme conditions as well, turning the darkest and deepest parts of this planet into alien – like

The moisture supply reduces stability of the atmosphere that establishes favorable environment for organizes conventions that act as a precondition to tropical cyclones. August through November is the time that the hurricanes activity

In terms of the slope (and other constants), what is the value of the dynamical spring constant k d? The standard equation of a straight

Voltage decays exponentially as the current flowing through the circuit grows exponentially to its maximum value. For series of equal time periods the inductor is charged to its maximum value of which the current value will never reach

More than 90 percent of the ozone within the earth’s atmosphere is existing here “comparatively high” meaning several parts/million- considerably higher than concentrations within the lower atmosphere, however, still lesser compared to the key atmospheric components. Its location is approximately 15 to 35 km above the surface of the earth.

Apart from a graph of charge on capacitor against time, another one for current against time was also plotted to current is affected by change on charge on capacitor. This could the give an immediate overview about the activities of a capacitor in a circuit.

40 percent of all energy consumption is dedicated to electricity generation. Power Grid Management is responsible for distributing this electricity generated from Oil, Coal, Gas, Solar, Wind, and Nuclear energy sources to meet demand. This system was originally composed of individual utility companies which were responsible for training their own operators.

The difference between the nonliving and the living is possibly not as evident as one might initially imagine (Chaisson, & McMillan 365). According to the scientists, some of the characteristics of live organisms are - A living organism may react to their environment and often when gets damaged can heal themselves.

Deserts cuts across the earth along the latitudes 200-350 (United Nations Environmental Programme 5). We are studying the deserts by looking at their unique factors. According to National Geographic, deserts are known to cover one-fifth of the earth’s land and are to be found on all the continents. Many people never have come across deserts in our life.

This easy explains the origin and evolution of Peralkaline rhyolites. According to Shanti (p.15) rhyolites are acid igneous rocks that appear to be fine-grained

Average velocity is the change in the position of an object in a given direction, divided by the time it took for the object to move from the initial position to the final position. The position vector r extends from the origin to the particle, while the velocity vector v points in the direction of the particle's motion. Other variables, which are appropriate for describing a moving particle, can be defined in terms of these elementary variables.

For instance, the toxic chemicals in open dumps often seep through the ground and contaminate groundwater (WeGreen-USA, 2014). Organic wastes will normally undergo degradation. During the degradation process, the wastes are broken down in the

The occurrence started around 1970. The Europa report film faces a lot of disastrous technical failures that lead to a lack of communication between them and the earth mission control. Despite the series of very dangerous crises, the Europa crew continues with the mission of reaching Europa where they encounter a lot of scientific mysteries. 

It is ecological degradation that manifests when these contaminants are released into rivers, groundwater, oceans, or lakes without steps taken to remediate these bodies of water by removing dangerous and toxic chemicals and compounds. Water pollution maintains a significant negative impact on the planet’s biosphere and destroys local ecosystems.

Despite the fact that today atomic theory is a well-known modern science cornerstone, such as germ evolution theory, throughout history, people had the belief that matter was perhaps constant and could randomly be broken down into

From geology point of view, Bay of Fund lies in a rift valley by the name Fundy Basin. It was formed as the rift began to separate from the

Satellites get a big and clear image of the earth’s cloud. The development of the GOES-R and JPSS has enabled scientists to capture images that are able to offer more accurate and reliable images that can be efficiently used to predict

In general, Heron of Alexandria is the inventor of the Heron’s fountain which he developed in the First Century AD. Through the reliance on air pressure and steam, Heron was able to construct items that were most appreciated as toys as they did not have industrial or commercial use at the time of invention.

It borders Huainan to the north, Chaozhou to the northeast, Chaohu to the southeast and Lu’an to the west. The city is gorgeous with a very

The management of the airline is quite creative and is always on the lookout for ways of coping with current situations. (Bailey, 2007).

Alfred Wegener is the German meteorologist largely credited for the foundation of plate tectonics and was the first to present scientific and diligent evidence about continental reconstructions; among these pieces of evidence include the geometric continental reconstructions, the geological match of continuity of structure, and the climate, sediment and the mismatch of sedimentary deposits with latitude.

This condition may not necessarily insinuate that the forces acting upon it are equal. Therefore, the total amount of force of the object is zero (0m/s/s). Objects in a state of equilibrium have an acceleration of 0m/s/s,

The members of NERC include the entire United States continent, Mexico, the northern portion of Baja California, and Canada. It is the North America’s electric reliability corporation and

Oil spillage occurs both in water and on land. The effects tend to have a serious impact on the environment. Terrestrial land spillages can cause the death of vegetation. This happens once the oil spills on land and

The force normally causes a stretch or compression on the object thereby causing a change in length. Naturally, the Rubber band fits this study since it is an elastic object which can stretch and compress upon the effect of a force. This experiment proves whether the characteristics of rubber bands make it a “non-hookean” or “hookean” material.

This was plotted as shown in figure 1 below. The second measurement experiment was conducted with the rod broken into a number of pieces. As the number of pieces increased, electric field calculation remained constant, but the numerical value

Radioactivity has the potential to cause both harm and benefits (Andrew & Stein, 2009). The process can be described as occurring randomly such that one cannot be in a position to identify which nuclei will decay at any given time but using probability, we can state the number of atomic nuclei that will decay in a given time.
