0.0006032 m2

उत्तर
0.0006032 m2 has four significant figures.
Explanation:
In numbers less than one, any zeros between the decimal point and the first non-zero digit are not considered significant; they merely set the decimal place. Therefore, the initial three zeros are not significant. However, the digits 6, 0, 3, and 2 are all significant, including the zero, because it lies between two non-zero digits, indicating precision in the measurement.

A man walking briskly in rain with speed v must slant his umbrella forward making an angle θ with the vertical. A student derives the following relation between θ and v: tan θ = v and checks that the relation has a correct limit: as v →0, θ → 0, as expected. (We are assuming there is no strong wind and that the rain falls vertically for a stationary man). Do you think this relation can be correct? If not, guess the correct relation.
