6. A user has opened a word processor, typed the numbers 123456789, and stored the document as a file called report1. Which of the following determines, in part, what bits the computer stores in the file to represent the text typed into the report? a. Keyboard map b. Pixel grid c. Character set d. The binary equivalent of decimal 123456789 7.
Follow all necessary steps as given in the documentation; you would now have generated a “.hex” file which you can load into the microcontroller. 4. You can load the “.hex” file by using Bootloader; steps for installing and using Bootloader is given in Refer section 2.6 (page 29) of the Software manual for complete instruction of using the AVR Bootloader on your system. Step number 5 and 6 will be same explained above in option 1. If Teams get doubts while taking the tutorial, they can post the queries on e-Yantra QuestionAnswer forum at
Before you begin, save this document to your computer. You will need to submit your answers in the area indicated below. | Directions: | Part I: 1. Read chapters 1 and 2 of your “Language of Medicine” textbook. 2.
File naming conventions differ by operating system. What file naming conventions does the operating system on your computer use? Using an Internet search engine such as Google or the LIRN Library[->0], research and explain the rules for both Windows and Mac OS. Be sure that your responses are written in your own words.

Experimental Data Trial 1 Trial 2 Trial 3 Sample Volume 10 mL 10 mL 10 mL Weight sample + capped vial 26.5g 26.5g 26.3g Weight vial + cap 15.5g 15.4g 15.4g Sample weight 11.0g 11.1g 10.9g Calculated Results Trial 1 Trial 2 Trial 3 Density of samples: 1.10g/mL 1.11g/mL 1.09g/mL Average density: 1.10g/mL 1.10g/mL 1.10g/mL Deviation from Average: ±0.00g/mL ±0.01g/mL -0.01g/mL Average Deviation: add absolute values of deviations from average and divide by the number of trials. +0.00++0.01+-0.01= 0.02 ∴ Therefore, the average deviation in density = ±0.02/3 = ±0.01 Average weight of 10mL Volume Samples 10mL x 1.1g/mL = 11g Percent Inherent Error in Average Weight of Samples ±0.1 g/reading*2 readings 11* 100 = 1.8~2% Percent Inherent Error in Average Volume of Samples ±0.1 mL/reading*1 readings 10 mL*100 = 1% Total Percent Inherent Error in Density ±2%+ ±1%= ±3% Inherent Error in Density 1.10g/mL x (±3/100) = ±0.03g/mL Conclusions Since the deviations from the average density are equal to or less than the total possible inherent error computed, it is concluded that the precision of the data collected was good. Second
There will have some error. 2) A volatile liquid was allowed to evaporate in a 43.298 g flask that has a total volume of 252 ml. the temperature of the water bath was 100˚C at the atmospheric pressure of 776 torr. The mass of the flask and condensed vapor was 44.173 g. calculate the molar mass of the liquid. T = 273 + 100 = 373 V = 252 mL = 1 L / 1000 mL = 0.252 L P = 776 Torr R= 0.0821 mass of 44.173 - 43.298 g = 0.875g moles of gas = PV / RT = 776 x .252 / 62.363 x (273+100) =0.00841 moles molar mass = 0.875g / 0.00841 moles = 104.1 g/
