Ocean Waves A wave is a periodic disturbance in space and time‚ possibly transferring energy to or through a space-time region. Have you ever ridden a wave in the ocean? Ocean waves travel on the surface of the water. You can see them and you can feel them. As you swim through the water‚ you can even make your own waves. The winds cause waves on the surface of the ocean (and on lakes). The wind transfers some of its energy to the water‚ through friction between the air molecules and the water molecules

Water Waves By Anna Introduction Water waves have been around for years; learning about water waves can help you understand the outside world. Water waves can be used in many ways‚ but they can also be harmful‚ too. When were they discovered? Water waves have been around since the creation of the earth‚ but Isaac Newton came up with a theory; after studying waves in about 1687. What is the biggest wave? In 1958 the biggest tsunami wave was recorded. How much harm can water waves really

Seismic Waves What are seismic waves? Seismic waves are the waves of energy caused by breaking of rock within the earth or an explosion. These waves are the energy that travels through the earth and is recorded on seismographs. There are many different types of these waves‚ but the two main ones are the body waves that usually travel though in inner layer of the earth‚ and the surface waves that only move around the surface of the planet. Body waves travel through the inner layer of the earth

Electromagnetic waves are radiated energy of all different strengths. They’re different from sound waves and water waves because they have the ability to travel through empty space. A vacuum. These are the only types of waves that do not need any type of medium because of photons. Photons are tiny particles that don’t get traveled through‚ but make up electromagnetic waves. Photons travel with the wave at about 300‚000 k/s. also known as the speed of light. The more energy the photons have‚ the brighter

THE TWO FACTOR THEORY (Herzberg’s Hygiene and Motivational Factors) Frederick Herzberg (1923-2000) developed a list of factors that are closely based on Maslow’s Hierarchy of Needs‚ except it is more closely related to work: Hygiene or Dissatisfiers – Working conditions • Policies and administrative practices • Salary and Benefits • Supervision • Status • Job security • Fellow workers • Personal life Motivators or Satisfiers - Recognition • Achievement • Advancement • Growth • Responsibility

The Duality of Human Nature One of the most vital concepts incorporated into The Strange Case of Dr. Jekyll and Mr. Hyde is the representation and depiction of the duality of mankind. Jekyll works to find a solution which will separate him into his reckless‚ immoral persona and his respectable‚ Victorian self. After consumption‚ this potion causes him to completely transform into a man who is known as Hyde. As Hyde‚ he can express himself in immoral‚ evil ways. This not only includes moral and

Characteristics and Nature of Waves In physics‚ a wave is a disturbance that travels through space and time‚ usually accompanied by the transfer of energy. Waves travel and the wave motion transfers energy from one point to another‚ often with no permanent displacement of the particles of the medium—that is‚ with little or no associated mass transport. They consist‚ instead‚ of oscillations or vibrations around almost fixed locations. For example‚ a cork on rippling water will bob up and down

everything is as it appears through its plot‚ the character’s language‚ and the events that take place. He demonstrates this with two literary devices; Duality and double entendre. The dualities in his play consist of love and hate‚ good and evil‚ and light and dark. With love there comes hate in Shakespeare’s play Romeo and Juliet. In this play the duality of love is demonstrated through the intense feud between the Capulets and the Montagues. “Here’s much to do with hate‚ but more with love” (II i 175)

OIL AND WEAR PARTICLE ANLYSIS Abstract: Oil and wear particle analysis is a very powerful tool used to monitor and assess the health of a machine. Since the lubricant in a machine passes through all the internal parts that can wear‚ it is vital to maintain the quality of the lubricant thought oil analysis. Furthermore the presence of wear particles that are deposited in the oil can give a good indication of the wear material and the possible location of the abnormal wear
