Problem 44P

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

(a) 0.00010320 s

(b) 1,322,600,324 kg

(c) 0.0001240 in.

(d) 0.02061 m

Solution 44P

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) 0.00010320 s

Thus, the significant not significant zeros are

(b) 1,322,600,324 kg

Thus, the significant not significant zeros are 1,322,600,324 kg

(c) 0.0001240 in.

Thus, the significant not significant zeros are

(d) 0.02061 m

Thus, the significant not significant zeros are
