( Photos 1:33 PM Tue 28 Sep © 90% Pre-Lab Unit 1 Pendulum Week 2 AA 2 of 2 b. If an uncertainty one fifth the value found in a. is desired how many measurements would be required (assume that the standard deviation with this number of measurements is the same as with ten measurements). 3. Ten identical blocks are placed in contact end to end. A meter stick is used to measure the total length resulting in a measurement of 50.35 ± 0.05 cm. What is the length of each block? Would a measurement of a single block with the same meter stick be as precise (that is have the same number of decimals)?
