2
There are two significant figures. In scientific notation 0.032 = 3.2 x 10^-2 → it has 2 sig fig.
1,002,000,000 in Scientific Notation = 1.002 x 109
The number 10 has two significant figures. Both digits, 1 and 0, are considered significant because the number is not written in scientific notation and does not have a decimal point. If it were written as 10.0, it would have three significant figures.
The number 1.89 x 10³ has three significant figures. The digits 1, 8, and 9 are all non-zero digits, which are counted as significant. The scientific notation does not affect the number of significant figures in the coefficient.

A scientific word for facts or figures would be data.
There are two significant figures. In scientific notation 0.032 = 3.2 x 10^-2 → it has 2 sig fig.
There are 4 significant figures. This can be seen by writing the number in scientific notation: 108700 = 1.08700 x 10^5 = 1.087 x 10^5 Removing the two trailing zeros makes no difference to the value of the number in scientific notation, therefore they are not significant.
