Question

physics lab Least Counts Given meter-length sticks calibrated in meters, decimeters, centimeters, and millimeters, respectively. Use the sticks to measure the length of the object provided and record with the appropriate number of significant figures in Data Table 1. DATA TABLE 1 Purpose. To express least counts and measurements. Actual length ___________ (Provided by instructor after measurements) Comments on the measurements in terms of least counts Find the percent errors for the four measurements in Data Table 1.

Explanation / Answer

Object length 1m,

6 dm,

60 cm,

602 mm

error = 1 m, 1dm, 1cm, 1mm

% error = 100% in m,

1*100/6 = 16.7% in dm,

1*100/60 = 1.67% in cm,

1*100/602 = 0.166% in mm
