Fundamental frequency

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…

“That all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.” When Thomas Jefferson wrote that iconic phrase for the Declaration of Independence, he was considerably influenced by the natural law philosophies of John Locke. Locke was one of the first to introduce the idea that property is acquired through labor, and that the value of that property is fundamentally intertwined with the…

are those of extraversion/introversion, agreeableness, conscientiousness, neuroticism, and openness, all of which are apparent in one’s behavior (“Personality Structure”). This was determined by the act-frequency approach, which emphasizes the correlation between a person’s actions and “the frequencies with which specific acts are performed during a specified period of time” (“Personality…

Fundamentals of Biochemistry in the Biotech Industry Maple Syrup Urine Disease: A Sweet Scented Killer Maple Syrup Urine Disease (MSUD) is a rare, potentially deadly disorder where the body cannot break down the three branched- chained amino acids (BCCA): leucine, isoleucine and valine. These amino acids are used to build proteins and when they are not being used they can be broken down and recycled in the cell. The complex that breaks these amino acids down is called BCKD (branched-chain…

Theories of evolution started before Darwin’s specific one by natural selection. The most prominent and perhaps influential on Darwin was Lamarck’s theory of “evolution by willing”, or that physical changes during an animal’s lifetime would be passed to offspring, in that it laid the foundation for his more developed explanation for evolution (Mayr, 1982). Darwin believed in evolution several before developing his theory of natural selection, he objected to Lamarck’s theory due to the lack of…

we can use the reversion rate to measure and calculate the mutagenic properties of our chemical Ethyl Methanesulfonate. Since EMS is proven and known to acquiring mutagenic capabilities, it should produce reversions in S.typhimurium TA1535 at a frequency comparable to other strong mutagen such as sodium azide or higher than the rate of a spontaneous…

signal is large. This amplitude variations in the received signal called signal fading, are due to the time-variant characteristics of the channel. Relative motion between Tx and Rx (or surrounding objects causing e.g. reflection) causes random frequency modulation. Figure 11 Multipath propagation Each multipath component has different Doppler shift. The Doppler shift can be calculated by using: fd=Vλcosα V is the velocity of the…

Evolution is the change in the heritable traits and genetic codes of biological populations over successive generations which can give rise to biological diversity. Generally, evolution also define as the process which modern organisms have descended from ancient ancestors and the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth. The genetic differences that are heritable will passed on to their offspring or the…

Breaks are not something people take the time to think about. Even if they are fundamental to the vehicles many people use every day. The functionality of breaks is contributed to physics and engineers ability to understand that physics. There is a lot going on when people press on the brake pedal in their car. The most basic principle of brake pads is in fact friction. This friction is the thing that transfers the energy of the car moving forward to heat energy. Brakes also use pressure as a…

Fragile X syndrome is defined as a genetic condition that causes intellectual disabilities, behavioral and learning challenges and various physical characteristics. This syndrome, being a genetically heritable disease, is X-linked. This makes the disease more commonly observed in males than females, about two to one. Males have roughly a one in four thousand chance of getting the syndrome and females have about a one in eight thousand chance (Bostrom). Some general characteristics can be seen as…
