How long must a flute be in order to have a fundamental frequency of 262 Hz (this frequency corresponds to middle C on the evenly tempered chromatic scale) on a day when air temperature is 20.0C ? It is open at both ends.
PH 1120 -- Resistors & Light Bulbs -- Lab Report Your Name: Jordan Counsel Partner’s Name: Katherine Conroy Section: F1 Date: 11/16/2016 1. Write down the values for your measured R an1 R in s2andard form (Uncertainty to one digit unless the lead digit is 1, in which case the first two digits are retained; the main value is then written with digits to the same decimal place as the uncertainty. This may very well involve more or fewer digits than the three we ask for on exams and summary homework – here it just depends on the precision of the particular experiment you are doing.). Resistors Measured Uncertainty Calculated R1= 51 49.28 .03481 51 R2= 68 64.55 .1877 68 R s 112.5 .1910 119 R p 27.78 .01617 29.14 2. The equivalent resistance of two resistors in series is given by R = Rs+ R 1 2 Because R a1d R are2independent of one another (determined by independent sets of measurements), the best-value uncertainty of R is determined by the s following method: square the individual uncertainties of R and 1 , add t2e squares together, and take the square root of that sum (this is called the “quadrature” of those two numbers). Now y
