Premium Physical quantities
Advantages: 1. They allow people across the globe to communicate with each other‚ no matter at what time‚ via the use of email. 2. They allow people to look up information directly‚ instead of the use of searching through books. 3. Back-up copies of work can be made easily‚ without having to re-write everything. 4. People can work from home‚ and spend more time with their families because of this. 5. People with disabilities whom can’t write‚ can get software that allows them to speak and it

INTRODUCTION Tachogenerator is an electromechanical device which generates an electrical output directly proportional to the speed of the rotating systems. Tachogenerators are basically transducers. This transducer converts the speed of rotation directly into electrical signal. The angular speed is converted into a directly dependent voltage signals. The voltage thus generated is fed to a speedometer for speed measurement and /or used as a feedback signal for controlling the speed of a rotating

Eric Wu 117 Experiment 1.6: Determination of Density Abstract: The purpose of the experiment was to determine if density is an intensive or extensive property of matter. The experiment proves that density is an intensive property. The density of an object remains the same no matter how much of it is present. The density is an intensive property because mass and volume changes at the same rate. Introduction: This experiment was designed to determine if density is an intensive or extensive

Sadie Broadway Speed of Sound In Air We are studying the speed of sound in air currently in our physics class. The speed of sound is the distance traveled by a sound wave through an elastic medium during a period of time. The speed of sound is extremely interesting‚ as it’s actually the speed of transmission of a small disturbance through a medium. The speed of sound occurs constantly‚ whenever a sound is heard. It’s everywhere‚ and in air we are discovering certain factors like altitude and air

AP10005 Physics I Tutorial 7 (Chapters 17‚ 18) 1. (17P11) A flower pot is knocked off a window ledge from a height d = 20.0 m above the sidewalk as shown in the figure below. It falls toward an unsuspecting man of height h =1.75 m who is standing below. Assume the man requires a time interval of Δt = 0.300 s to respond to the warning. How close to the sidewalk can the flower pot fall before it is too late for a warning shouted from the balcony to reach the man in time? 2. (17P15)

a. DO3SE model: Basically‚ DO3SE model is derived from the Jarvis-type multiplicative algorithm: gsto = gmax X min (fphen‚ fO3) X flight X max (fmin‚ (fVPD X ftemp) (1) where gsto is the actual stomatal conductance for O3 (mmol O3 m-2 unit projected leaf area (PLA) s-1)‚ gmax is the species-specific maximum gsto (mmol O3 m-2 PLA s-1)‚ and fmin is the relative minimum gsto (fraction of gmax). The parameters including ftemp‚ fphen‚ flight‚ fO3 and fVPD are the response functions expressed in

Exercise 1: The Organism and Its Environment GUIDE QUESTIONS 1. a. In the first part of the exercise conducted‚ the abiotic factors influencing the forest and the grassland community were measured. Despite the two sites being in close range of each other‚ they have significant differences that set them apart from each other. Table 1.1 shows the comparison between the two communities. The four factors measured were air temperature‚ soil temperature‚ light intensity‚ and relative humidity
