Fuel and energy-Why are fuel and energy important? I chose this topic because I think; it plays an important role in our life. Without fuel and energy‚ I wouldn’t be able to arrive to school on time‚ because I need to come to school by car‚ which would not work if there is no fuel. I wouldn’t be able to use Air Conditioner‚ because it need electricity to works….and many more example. The point is without fuel and energy‚ most part of our life would be meaningless. So it is important for us‚ that

INTRODUCTION Sound is a mechanical wave an oscillation of pressure transmitted through a solid‚ liquid‚ or gas‚ composed of frequencies within the range of hearing and of a level sufficiently strong to be heard‚ or the sensation stimulated in organs of hearing by such vibrations. Sound is a sequence of waves of pressure which propagates through compressible media such as air or water. (Sound can propagate through solids as well‚ but there are additional modes of propagation). During their propagation

S1523 Project Title The Focalization of Sound Abstract Objectives/Goals Scientists have been able to focus sound waves by transmitting an ultrasonic wave in a straight line that can give off audible sound in its path. The only disadvantage to this is the high cost. This project was designed to develop a low-cost process of focusing sound using a parabolic dish and sound-absorbent material. Methods/Materials The project began with the building of a sound box to test different materials in. The box

The sound element narration‚ dialogue‚ sound effects and music makes the nonrealistic characters come alive. What we hear gives life to what we see and offers some clues to the meaning. Once we identify the sound on the action we suspect that it is warning for what going to happen litter on the

What is sound? Sound is a wave‚ a pattern—simple or complex‚ depending on the sound—of changing air pressure. Sound is produced by vibrations of objects. The vibrations push and pull on air molecules. The pushes cause a local compression of the air (increase in pressure)‚ and the pulls cause a local rarefaction of the air (decrease in pressure). Since the air molecules are already in constant motion‚ the compressions and rarefactions starting at the original source are rapidly transmitted through

How important is it to explore alternative forms of energy? Energy is the source of life. Energy that we gain from food helps us to survive. It implies that food is a source of energy for us. The vehicles that we use‚ the industries that manufacture different products are all dependant on some kind of energy source. The source may be electricity or fossil fuel but it is clear that everything needs an energy source to run. In the old days firewood was the energy source. After the invention of automobiles

Energy is something vital that drives everything- people‚ animals‚ plants‚ gadgets‚ industries‚ offices‚ and all the institutions or the activities one can imagine. It is the energy- be it a mechanical‚ chemical‚ tidal‚ wind or hydropower-that has created the world with different artificial stuffs and; compelled people to live in fantasies and search for newer ways to fulfill their dreams. This has been the same for quite a long period of time that people are eager to live better lives. A better

Sound and acoustics It is common to think that acoustics is the study of music. Although acoustics does comprise the study of musical instruments‚ it also includes an extensive range of topics‚ including: SONAR systems‚ noise control‚ ultrasounds for medical imaging and other processes‚ electroacoustic communication‚ seismology‚ etc. [1] In general‚ acoustics is the study of mechanical waves including sound‚ vibration‚ infrasound and ultrasound. When talking about the acoustics‚ it is essential

Sound A. What is the definition of Sound? Sound is everything that a person‚ animal or computer can hear. It can be created in a countless number of ways and occurs from anything as simple as tapping on a table. All sounds are a series of vibrations that travel through a medium in all possible directions. The cause of sound is the vibration of an object; once the item vibrates the sound waves then radiate outwards until they are either stopped or they die out. A sound wave has three characteristics:
