Communication Errors When information is transferred back and forth among the various parts of a computer‚ or transmitted from the earth to the moon and back‚ or‚ for that matter‚ merely left in storage‚ a chance exists that the bit pattern ultimately retrieved may not be identical to the original one. Particles of dirt or grease on a magnetic recording surface or a malfunctioning circuit may cause data to be incorrectly recorded or read. Static on a transmission path may corrupt portions of the

October 1962 was one of the most dangerous times for the world in recent history. The text being examined in the essay is that of an extract from the Kennedy Tape transcripts. These were a set of secret tape recordings that President J.F Kennedy had made during his time in the white house. The only people aware of these recordings at the time were J.F Kennedy himself‚ his private secretary‚ the two guards who manned the machine and perhaps his brother‚ Robert Kennedy. The conversation that was recorded

Introduction: The Speed of Toy Cars & Measuring Acceleration was investigated by using a ticker timer and changing the angle of the ramp. Changing the angle of the ramp affects the speed and acceleration of the trolley. The speed and acceleration of the trolley was determined by using the ticker timer. Aim: The aim of the practical is to investigate the motion and acceleration of a trolley by using a ticker timer and rolling the trolley down a ramp. Variables: Independent Variable – The independent

that the acceleration due to gravity (or g) is approximately 9.8m/s2 [down] or -9.8m/s2 [up]. What we are trying to do is design an experiment to measure and confirm this value. Our plan was to drop an object from a reasonable height and use a ticker tape timer to measure the amount of time and distance travelled between each time. The weight of the object used would have to be heavy enough that it would not be affected by air resistance. For example‚ you shouldn’t use a piece of paper because due

Scientific question: How does the incline of a slope influence the acceleration of a cart when it travels down a wooden plank? Introduction: What is an incline plane? Commonly referred to as a ramp or a slope‚ an incline plane is an even surface that is titled at an angle. An object placed on the tilted surface will often slide down the surface‚ accelerating because of an unbalanced force. The rate at which an object travels down the slope is dependent upon how tilted the slope is; the greater

Materials/Apparatus: One ticker timer One carbon paper disc One 1.5+ meter tape One test tape One stop-watch Theory: The recording timer is a device that helps you study motion‚ it is a simple electric device plugged into mains power‚ with a stylus that vibrates up and down. The stylus hits a tape that can be drawn through leads‚ and presses it onto the carbon disc below. This leaves a dot on the tape for every hit. The power source
