Oscillation

waves that gives us different perception. We all know that higher frequency sound waves have higher pitch. The faster the oscillation, the higher pitch sound it gives. Our ears can only detect a certain range of the frequencies, called the audible spectrum or audio frequency. Although the audible range differs from person to person, it is generally from 20 to 20,000 oscillations per second. Sound having frequency greater than the upper limit of the audible spectrum is called ultrasound. Prenatal…

All metal manufacturing includes a solidification process. The metal is either atomised to a powder, or it is cast. There is several casting methods used today. Many of the methods use the mould only once, for example sand mould casting, the lost-wax method and precision casting. For larger quantities of liquid metal, there are basically two methods: ingot casting and continuous casting. Ingot casting normally uses a permanent mould made by cast iron isolated by ceramic material. There are…

calculate the period of a pendulum. The period was measured by repeatedly timing the time it took for the pendulum to return to its original position once it was swung from a certain point (for the first method one oscillation was timed, however in the second and third ten oscillations were timed and the overall time was divided by ten; the length of the pendulum rod was altered also for the third experiment to create a varied range of lengths). Using the derived equation for the period of a…

As the length of the pendulum decreases, the time elapsed to reach a full oscillation decreases. The relationship follows the functional relationship of a linear function, as "X" (length of pendulum) decreases, "Y" (Time elapsed for oscillation) decreases. Report Question: Bio-metrology According to Table 5, there was no correlation between the circumference of a person's head and their heart rate. One reason…

simple type of oscillation called “isochronous”, which means it always takes the same time. Therefore these are oscillations that always repeat in the same time period maintaining the same this constant time even with a change in amplitude. A simple pendulum follows this pattern and it is why it has been such an important element in clocks. This can also be applied in different gravitational field strengths as the motion of the pendulum will always take the same time for one oscillation.…

different time scales, causing climate events like El Nino-Southern Oscillation and Decadal Oscillation. This shows that the slow increase of heat in the Earths Ocean and atmosphere influence the strength and direction of its major current systems. These shifts in the patterns of ocean currents are capable of having great impact on the allocation and amount of marine ecosystems, which is shown by many El Nino-Southern Oscillations and their impacts on kelp forests and coral reefs…

Nikola Tesla, (1856-1945) was the inventor of the World’s lighting and well-known for his contribution to the world of science and technology. Tesla, a son of priest from Orthodox faith, he was born in born in Serbian in the territory of Yugoslav. He is the first inventor of the outstanding radio communication. Tesla is also known for his invention, who devised the powerful alternating current (AC) model that significantly became the industry electric standard. AC is widely considered one of the…

weather pattern that affects the planet is called El Nino Southern Oscillation or ENSO, in which the ocean comes together with the atmosphere in a harshly consisting pattern. ENSO makes warm water move back and forth across the surface of the Pacific Ocean in some measure in response to drastic changes in the trade winds. Mechanisms that cause the oscillation remain under study. The extremes of this climate patterns oscillations cause extreme weather. The most affected are…

The human skeleton system is a highly dynamic organ made up of a total of 213 bones in adults . It is formed by a mineralized connective tissue and comprises two mainly cellular types: osteoblast-lineage cells, and osteoclast-lineage cells. The skeletal system exerts fundamental functions in the body, such as supporting and providing mechanical protection to soft tissues; storing several minerals (mainly calcium and phosphate), and releasing them in the blood stream when required; harboring the…

Increased inertia means that the springs will not be able to make the mass change direction as quickly. This increases the time period of the oscillation. The greater the inertia of an oscillating object, the greater the time period which therefore lowers the frequency of its oscillations. Depending on how the waves are displaced indicates how big the oscillations. The elasticity of a spring also can be quantified by a measure of a spring’s compliance. Compliance is inversely related to…
