Sound is a vibration that spreads across a medium (i.e.‚ air or water) as a mechanical longitudinal wave formed by pressure. A Mechanical longitudinal wave can also be called compression wave as it generates compressions and rarefaction when traveling through a medium. (Sound Is a Pressure Wave - Physics Classroom) The amplitude of a sound wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave. The Speed of sound deviates with the temperature

Tachyon particles are theoretical particles that supposedly have a minimum speed of the speed of light. Tachyons‚ (from the greek word ‘tachys’‚ meaning swift)‚ have never been found in experiments‚ but scientists think that they exist as faster-than-light “quasiparticles”. In the 1960s‚ some physicists wondered what would happen if matter could travel faster than the speed of light‚ something that is supposed to be impossible according to Einstein’s Theory of Special Relativity. Tachyons were first

tive if there existed a decline in population. Otherwise‚ r can be found as a ratio of the birth rate to the death rate. If we let 1 + r = b‚ the base of the exponential expression‚ the function becomes p = p 0bt. An alternative version of this relation describes the time it would take for the population to reach a given amount p: t = logb( p / p0). Students will use both functions to predict the future global population‚ provided the current growth rate or 1.3% (Abbott‚ 2004). This relation will

The Elvis Experiment Introduction: In this experiment we will determine how the difference in length and diameter of a blood vessel have an effect on the resistance of blood flow and how the viscosity of blood will also effect the resistance of blood flow in a blood vessel. Observation: My mom is a big Elvis fan and she always wondered how his health affected his death. Knowing that he had high cholesterol and high blood pressure I decided to do an experiment on what factors may have had an effect

X-rays and Ultrasound: X-rays and ultrasound are two different modalities used for different things‚ so an ultrasound can do some things an X ray cannot‚ and vice versa‚ and so this makes them very difficult to directly compare. Ultrasound: Above: An ultrasound machine. Ultrasound is the use of energy generated by sound waves of 20‚000 or more vibrations per second. Ultrasounds are generated by a device called a transducer. Bearing in mind that sound is a mechanical energy‚ the transducer

A 200 Year Democracy Our nation is approximately two hundred and thirty years old‚ and our democracy‚ the same. According to Alexander Tyler a democracy only lasts an average of two hundred years; so we are overdue right? I don’t think so‚ and I shall tell you why. I don’t think we are overdue. No‚ not at all‚ I just think we are running a little late to the party‚ so to speak; however we are well on our way there. Alexander Tyler said that a democracy will fall at the hands of a loose fiscal
