Problem 43P

For each measured quantity, underline the zeros that are significant and draw an X through the zeros that are not.

(a) 0.005050 m

(b) 0.0000000000000060 s

(c) 220,103 kg

(d) 0.00108 in.

Solution 43P

Here we have to find out the significant zeros from each number. There are few rules to find out the significant figures. These are

- When zeros are present in between the nonzero digit, then zeros are considered as significant figures.
- When zeros are in the beginning of a number, then it never be significant figures.
- When zeros are at the end of a number and it contains decimal point, then it will considered as significant figures.

(a) 0.005050 m

The significant and insignificant zeros are

The significant zeros are

(b) 0.0000000000000060 s

The significant and insignificant zeros are

(c) 220,103 kg

The significant and insignificant zeros are 220,103 kg

(d) 0.00108 in.

The significant and insignificant zeros are
