QuestionCount the significant figures in these measurements: , , .
Studdy Solution
STEP 1
Assumptions1. The measured quantities are , , and . . The rules for determining significant figures are as follows a. All non-zero digits are significant. b. Any zeros between significant digits are significant. c. Leading zeros are not significant. d. Trailing zeros are significant only if they are after a decimal point.
STEP 2
First, let's find the number of significant figures in . According to the rules, all non-zero digits and zeros between them or after a decimal point are significant.
STEP 3
Count the number of significant figures in .
There are four significant figures in .
STEP 4
Next, let's find the number of significant figures in . According to the rules, all non-zero digits and zeros between them are significant. However, trailing zeros without a decimal point are not significant.
STEP 5
Count the number of significant figures in .
There are five significant figures in .
STEP 6
Finally, let's find the number of significant figures in . According to the rules, all non-zero digits and zeros between them or after a decimal point are significant.
STEP 7
Count the number of significant figures in .
There are six significant figures in .
So, the number of significant figures in , , and are four, five, and six respectively.
