How many significant figures can be recorded on the time of a stop watch?

Answer 1

The number of significant figures that can be recorded on a stopwatch typically depends on the resolution of the stopwatch itself. For most digital stopwatches, the time can be recorded to the nearest hundredth of a second, allowing for three significant figures (e.g., 12.34 seconds). Analog stopwatches may vary, but they often provide two significant figures (e.g., 12.3 seconds) depending on the precision of the measurement. Ultimately, the precision of the stopwatch dictates the number of significant figures that can be reported.
