Question
of South Alabama Physics PH 201/PH 202 Laboratory Manual University at time and evaluating which bin the time in. For example: the has bins box the etc. time s, if marked in the bin described by o 16 to o 18. If a bin already has an "x in a second "x" X division ismarked in the major above it. This procedure is repeated until all values are graphed. After the histogrammed, mark avertical line on your histogram through the mean. Also mark data is standard and t three standard vertical line at the mean t one standard deviation, t times for u to for Aut2o and for deviations. Finally, calculate the percentage of your reaction expected values? Auto. Are the percentages you calculated comparable to the 1.5 Preliminary Assignment the object has fallen Using the equation that relates the distance an object falls to the time (Equation (1.5), solve for the time as a function of the distance fallen. 2) A student performs the experiment and records the following values for the time the meter stick has fallen: 0.167 4 0.162 14 0.193 24 0.201 5 0.188 15 0.169 25 .197 6 0.167 16 0.212 26 0.143 7 0,219 17 0.153 0.169 27 8 0.151 0.169 28 0.179 18 90 0.181 0.228 30 0.148 A) Calculate the average and standard deviation of the reaction time from this data. B) Determine the bin width for the histogram.Explanation / Answer
Here, equation
=> S = ut + 1/2at2
=> 5 = 1/2 * 9.8 * t2
=> t = 1.01 s
Thus, time taken = 1.01 s
average time = (t1 + t2 + t3 + ... + tn)/n
= 0.151 s
standard deviation = 0.11 s
bin width of histogram = (0.189 - 0.172)
= 0.017 s
