Question

1. what is the uncertainty of a time measurement from a stopwatch that has smallest intervals of 0.01 seconds? (hint: this is a digital reading from the stopwatch)

Explanation:

Step1: Identify uncertainty principle

For a digital measuring device, the uncertainty is equal to the smallest division.

Step2: Determine the value

The smallest interval of the stop - watch is 0.01 seconds. So the uncertainty is 0.01 seconds.

Answer:

0.01 seconds
