QuestionFind the significant figures in the measurement: .
Studdy Solution
STEP 1
Assumptions1. The measured quantity is . We are following the rules of significant figures which state that a. Non-zero digits are always significant. b. Any zeros between significant digits are significant. c. Leading zeros are not significant. They are only placeholders. d. Trailing zeros in a number without a decimal point are not significant. They could be placeholders. The ambiguity can be resolved with scientific notation. e. Trailing zeros in a number with a decimal point are significant. They indicate the precision of the measurement.
STEP 2
We need to identify the significant figures in the given quantity. According to the rules of significant figures, we start counting from the first non-zero digit.
STEP 3
In the given quantity , the first non-zero digit is6. So, we start counting from6.
STEP 4
We continue counting, including zeros that are between non-zero digits. In this case, the zeros between6 and8 are significant.
STEP 5
We stop counting after the last non-zero digit, which is1 in this case. The trailing zeros after1 are not significant because there is no decimal point in the number.
STEP 6
Count the number of significant figures.
The number of significant figures in is5.
