object that is struck with a sound wave of equal sound wave vibrations will amplitude the given tone. This would explain the reason why some singers are able to break wine glasses with their voice. The vibrations build up enough to shatter the glass. This is called RESONANCE. Resonance can be observed on a tube with one end open. Musical tones can be produces by vibrating columns of air. When air is blown across the top of the open end of a tube‚ a wave compression passes along the tube

BASIC IDEAS FOR FINAL YEAR PROJECT SELEC TION FOR ELECTRICAL & ELECTRONICS STUDENTS Project works are totally new to most of the engineering aspirants’ and is a blank slate to start with. It is an amorphous and a blank image to the students as they were earlier used to theory courses with prescribed text books and lab works that need to be carried out in the laboratory. A Project work is fortitude of common goal and group approach. Each passing year the engineering scholars are assigned project

in the end the impact of automation is great on our culture and lifestyles if we didn’t have them we wouldn’t function. • saves time • more efficant in cost • It is able to provid more and able to sell more The use of automation in the wave of the future‚ there is no denying it or fighting it. For every development there are downfalls of course‚ the increasing laziness and narcissism is a major downfall of our increased availability of technology. For example‚ nobody cares that you had

control circuit of the EMS‚ where the control circuit inverts the 9v dc into a pulsating wave. The preset level controller is used to vary the frequency of the EMS to low‚ medium and high. The lower the resistance the higher the stimulation‚ the higher the resistance lower the stimulation. The intensity control is used to determine the intensity of the stimulation. The transformer is used to output a sinusoidal wave which varies from (30-60) Vac. The electrodes are generally pads that adhere to the skin

piezoelectric crystal energy source is that of creating a small motor; such as that used in a reflex camera to operate the auto focus system. These motors operate by vibration. The two surfaces are forced to vibrate at a phase shift of 90 degrees by a sine wave that has been generated at the motors resonant frequency. This forces a frictional force where the two surfaces meet and as one of the surfaces is fixed the other is forced to move. It has been found that piezoelectric crystals that have been embedded

What exactly is the electromagnetic spectrum? Is a continuous range of wavelengths‚ which includes gamma rays‚ ultraviolet waves and other forms of electromagnetic radiation. How does the issue of scarcity and interference relate to the electromagnetic spectrum? The spectrum is considered scarce because of the limited number of frequencies for operation and two parties cannot broadcast on the same frequency in the spectrum. Interference not only can be caused by broadcasters but by natural phenomenons

3 x 108 m/s. 6. The frequency of a signal is equal to the reciprocal of the signal’s period (f = 1/p). For a computer with a 2.4 GHz clock‚ what is the clock period? Use metric notation for your answer. 7. The signal shown below is a sine wave as it might be displayed on an oscilloscope. If it takes 40 msec. for the waveform to travel between the points shown by the arrow “B” below‚ what is the frequency of the waveform? 8. Power (in watts) is a certain amount of energy (in joules)

2014 Moral Standing on Abortion To say that a person has moral standing is to give consideration to his or her wellbeing. According to Robert M. Veatch’s The Basic of Bioethics‚ moral standing is believed to be “that humans (at least normal humans) have moral standing [as well as] other animals” (27). Moral standing is determined by the physical or mental capacities of self-awareness or rationality. However‚ controversy arises when determining when one actually has full moral standing. Abortion

Dispersion and the speed of light “So far as problems involving light are concerned‚ the electrons (in atoms) behave as though they were held by springs”.Feynman “In a microscopic but otherwise classical analysis‚ the electric field in electromagnetic radiation accelerates electrons held by springs in the atoms of a piece of glass‚ and these accelerated electrons re-radiate in all directions. The observed light is the superposition of the electric (and magnetic) fields of the incoming
