This is then a cylinder whose trace in every plane parallel to the yz-plane is the parabola z = y2. © The McGraw-Hill Companies‚ Inc. Permission required for

Surface Waves: Understanding its movements I. Introduction We treat here an important wave phenomenon‚ the surface wave. It occurs in many physical systems both mechanical and electromagnetic. Mechanical surface waves can exist at the interface between two media with different densities such as the oceans and air. Ordinary sea waves and tsunamis are surface waves. Seismic events can produce both longitudinal and shear waves at the earth’s surface‚ resulting in earthquakes. Electromagnetic surface

My favorite season is summer. I like the other seasons as well‚ but summer is the best for me. First of all‚ I like summer because the weather is hot. Some people think that summer is too hot‚ but I just love it as it is. The sky is always blue and it hardly ever rains‚ and if it does‚ it is a warm and pleasant rain. I usually enjoy walking in the rain because it relaxes me. I like spending the long summer days out and sometimes even the short and warm nights. I like this season very much because

electric storms‚ hurricanes‚ blizzards and heat waves‚ just to name a few. Who would have thought that in beyond our atmosphere‚ in outer space‚ there is also weather occurring? It is true. Although the space weather does not occur in the ways in which most people‚ those that are not scientists or astronauts‚ would think of. Space weather is the “turbulent and dynamic” outputs from the Sun. These outputs can be in the form of light or particles that are electrically charged. Our magnetosphere

Surface Tension My problem was to find out how to test or measure surface tension. I think the reason of some of the force in surface tension is cohesion and gravity. Surface Tension is the condition existing at the free surface of a liquid‚ resembling the properties of an elastic skin under tension. The tension is the result of intermolecular forces exerting an unbalanced inward pull on the individual surface molecules; this is reflected in the considerable curvature at those edges where the

Adsorption: The accumulation of molecular species at the surface rather than in the bulk of a solid or liquid is termed as adsorption. Adsorbate: The substance which is being adsorbed on the surface of another substance is called adsorbate. Adsorbent: The substance present in bulk‚ on the surface of which adsorption is taking place is called adsorbent. Desorption: The process of removing an

Igneous Rocks Igneous rocks originate from deep within the Earth’s crust. Igneous rocks (from the Greek word for fire) are formed when magma crystallizes and solidifies. An increase in temperature‚ a change in the composition‚ or decrease in the pressure can cause melting of these rocks in the mantle which form igneous rocks. The melt begins deep below the surface of the Earth close to active plate boundaries. As the temperate increases the rocks rise toward the surface. Igneous rocks are divided

’Lawin’ slightly weakens Reporter 1: Typhoon ‘Lawin’ gets stronger‚ heads far northern Luzon Typhoon “Lawin” sped up slightly as it continued its movement towards the northern Philippines‚ the state weather bureau said. At 4 p.m. Wednesday‚ the eye of the supertyphoon was plotted by satellite and surface data at 410 kilometers east of Aparri‚ Cagayan according to the Philippine Atmospheric‚ Geophysical Astronomical Services Administration (Pagasa). The details will be delivered by Reporter 2 (name)

The difference between weather and climate is that weather consists of the short-term (minutes to months) changes in the atmosphere. Most people think of weather in terms of temperature‚ humidity‚ precipitation‚ cloudiness‚ brightness‚ visibility‚ wind‚ and atmospheric pressure‚ as in high and low pressure. There are lots of factors that influence our climate Elevation or Altitude effect climate Normally‚ climatic conditions become colder as altitude increases. “Life zones” on a high mountain reflect

THE ROCK CYCLE ● ● ● ● There are three main types of rocks: igneous‚ sedimentary‚ and metamorphic. Each of these types of rocks are formed in different ways and each type of rock can be changed into the other types of rock. This process is called the Rock Cycle. The rock cycle is the process that makes and recycles rocks. IGNEOUS ROCKS ● ● ● ● ● ● Igneous rocks are formed from magma. Magma cools and solidifies into rock. When igneous rocks are exposed on the surface‚ time and weather break the
