Fig4: Compressor and Motor e. Rheostat: A rheostat is an electrical component that has an adjustable resistance. It is a type of potentiometer that has two terminals instead of three. The two main types of rheostat are the rotary and slider. The symbol for a rheostat is a resistor symbol with an arrow diagonally across it. They are used in many different applications, from light dimmers to the motor controllers in large industrial machines.
75uS is the time constant used for a high-pass filter to enhance the high frequency audio before transmission to help reduce noise upon reception. The PLL is the portion of the IC which locks your chosen transmission frequency to the crystal reference X1. The PLL portion also contains an oscillator circuit which works in conjunction with the external parts of D5 and the STUB (that weird trace on the back of the board). D5 is called a varactor diode, and is a special variety of diode that is connected backwards. As a reverse DC voltage is applied across the diode, its capacitance varies.
The stronger the magnet the greater the field. The static magnetic field can have mechanical effects on the pacemaker. It has been known to effect certain parts of the pacemaker allowing it to revert to different intervals of pacing. It also has the ability to reprogram or reset the device all together. The static magnetic field exerts a magnetic force that can dislodge the pacemaker leads.
Chapter 1 Introduction to Computer Data 11. Which of the following answers best describes how a hard disk drive physically writes a binary 0 or 1? a. Using an electrical charge b. Using a magnetic charge c. Changing the disk’s surface so that later the light will reflect differently for 0 or 1 d. Holding a sound wave in a vacuum 12.
Unit 393 Sensory Loss Communication methods Sight loss People who are blind or partially sighted mostly use Braille to read, Braille is a tactile reading code where the paper has been embossed with bumps in a particular formation to represent a letter of the alphabet which enables blind or partially sighted person to access information by touch, Braille is also used on packaging for medications so a blind or partially sighted person can take their medication when required without the need for any help from a carer this helps increasing independence. Blind and partially sighted people also use audio to read For example, blind and partially sighted people may use products with audio feedback such as talking books, clocks, thermometers or weighing scales. Hearing loss. A deaf or hard of hearing person may use Sign Language to communicate, each country has their own form of sing language in this country (Britain) the British sign language (BSL) was officially recognised as a language in 2003 by the government. Under the Disability Discrimination Act, because Deaf people have the right to have access to information in British Sign Language if they are from this country.
The sound wave then enter into the eardrum where vibrations are matched. The eardrum sends the vibration waver to the middle ear whose job is to transfer sound waves to the hammer, the anvil, and the
Friction also has an important role to play in the construction of a rollercoaster. A roller coaster converts stored energy, (formula = mgh) which is known as gravitational potential energy into energy
Chalk: traditional and teacher-cantered, formal. It has its uses, BUT: There are other aids, both low-tech and high-tech, that create active learning. I.

The live guitar is amplified to blend well with the backing tape. Texture. Electric Counterpoint starts with a sparse texture however the piece is mostly contrapuntal. The texture is built up as more guitar parts are brought in and is gradually thinned towards the end as parts drop out. Interweaving rhythms give the impression of a changing texture.
The piece begin monophonically with the live guitar playing a one bar ostinato. Layers are added as three other guitars play the same motif but using phasing and this creates layering and the 'four part guitar canon.' the live guitar then plays the resultant melody which is the melody that stands out to the listener when two or more melodies are combined. The piece is now polyphonic. When the bass guitars enter, they are both panned to both
