How many significant digits are in the measurement 4,032,010 m/s?

6

Explanation:

The rules which we have to use to find the number of significant figures here are given below:

1. If a number does not contain a decimal point, then the zeros between two non zero digits are significant.

2. the trailing zeros are not significant.

The number is

4,032, 010 m/s

so, the zero between 4 and 3 is significant

the zero between 2 and 1 is significant

the zero at the last is not significant

So, the number of significant figures are 6.

the answer is to check all of them! they all apply well at least i think so!
