Question: If a length is measured as 0.0600 m, how many significant figures does it have?

Options:

Correct Answer: 4

Solution:

The number 0.0600 m has 3 significant figures. The leading zeros do not count, but the trailing zeros after the decimal point do.

If a length is measured as 0.0600 m, how many significant figures does it have?

If a length is measured as 0.0600 m, how many significant figures does it have?

Step 1: Identify the number given, which is 0.0600 m.
Step 2: Look at the leading zeros (the zeros before the first non-zero digit). In this case, the leading zeros are '0.0'. These do not count as significant figures.
Step 3: Find the first non-zero digit, which is '6'. This is the first significant figure.
Step 4: Count the digits after the '6'. The next digits are '0' and '0'. Both of these zeros are significant because they come after a decimal point and a non-zero digit.
Step 5: Add up the significant figures: '6' (1st), '0' (2nd), and '0' (3rd). This gives a total of 3 significant figures.
