graph should go through the origin and lastly‚ finding the mass needed to create a one second timer. It was investigated by placing a motion detector under a spring that was attached to a clamp which was attached to a retort stand. The mass was pushed above its equilibrium and the position vs. time graph was recorded. It was found that it was related by P(s) = 0.04m^0.5‚ it would take 625 g to make it a 1s timer and the graph would pass through the origin. Purpose: When a mass hanging on a spring

Question-1: How would you forecast the manpower needs of Ya Kun? There are few ways by which we can forecast the manpower needs of Ya Kun Kaya. They are: * Trend analysis * Ratio analysis * Scatter plot and * Computerized system Based on trend analysis‚ we can find new recruit by studying the variation of their past employment levels which means that they can provide an initial estimate of future staffing needs‚ but employment levels rarely depend just on the passage of time

Microcontroller A microcontroller (mcu or µc) is a small computer on a single integrated circuit consisting of a relatively simple CPU combined with support functions such as a crystal oscillator‚ timer‚ watchdog‚ I\O etc. Microcontrollers are designated for small applications. Thus‚ in contrast to the microprocessors used in personal computers and other high performance applications‚ simplicity is emphasized. Microcontrollers operate at frequency as low as 12 MHz‚ as this is adequate for many

He did not care about how much colder it was. To him‚ it was just a number. He did not think of his "frailty as a creature of temperature." When the "old-timer at Sulphur Creek" warned him not to travel alone in such cold‚ the man laughed at him. The old-timer had experience and knowledge‚ yet the man called him "womanish." Even when the man knew he was about to die‚ he thought‚ "freezing was not so bad as people thought‚" and "When he got back to the States
