Question

Let's say you have a plot for Pendulum experiment. Let's assume g for this experiment was measured (from the slope of the plot) to be 9.78 [ms-2.
The vertical intercept, however, is 0.014 [s2].
What might this translate to for a measurement of the length offset systematic in all the length measurements?
Length Offset = ????[mm]
Use 2 sig figs or N/A if no answer due to not enough information.

You time a pendulum for 50 cycles.
Given a stopwatch reading of 2:46.48, what is the period (in seconds)?
???????s
Use three sig. figs.
(Write N/A if there is not enough information.)

Explanation / Answer

the time period of the pendulum is T = 2 * (l/g)1/2 or T2 = 42 * (l/g) or l = (T2 * g/42) T2 = 0.014 s2,g = 9.78 m/s2 or l = (0.014 * 9.78/4 * (3.14)2)
       = 0.00346 m
       = 3.46 * 10-3 m
   = 3.46 mm

the time period of the pendulum is T = 2 * (l/g)1/2 or T2 = 42 * (l/g) or l = (T2 * g/42) T2 = 0.014 s2,g = 9.78 m/s2 or l = (0.014 * 9.78/4 * (3.14)2)
       = 0.00346 m
       = 3.46 * 10-3 m
   = 3.46 mm

the time period of the pendulum is T = 2 * (l/g)1/2 or T2 = 42 * (l/g) or l = (T2 * g/42) T2 = 0.014 s2,g = 9.78 m/s2 or l = (0.014 * 9.78/4 * (3.14)2)
       = 0.00346 m
       = 3.46 * 10-3 m
   = 3.46 mm

or l = (0.014 * 9.78/4 * (3.14)2)
       = 0.00346 m
       = 3.46 * 10-3 m
   = 3.46 mm
