read the elapsed time on the stopwatch and answer the questions. in which digit is there the least amount of confidence? how many significant figures does this measurement have?
Answer
Explanation:
Step1: Identify least - confident digit
The last digit in a measurement is the estimated digit and has the least confidence. In the stop - watch reading $0:13.37$, the digit $7$ is the least confident as it is the estimated digit in the hundredths place of the second measurement.
Step2: Determine significant figures
Non - zero digits are always significant. In the number $13.37$, all digits ($1$, $3$, $3$, $7$) are non - zero. So, there are 4 significant figures.
Answer:
The digit with the least amount of confidence is 7. The number of significant figures is 4.
