Number of significant figures in 0.0173 is_________________?
Correct answer: A. 3
- A. 3
- B. 4
- C. 5
- D. 2
Explanation
In 0.0173, the zeros before 1 are leading zeros and are not significant; the digits 1, 7 and 3 are significant. Therefore there are 3 significant figures, while students may choose b by counting the leading zero as a measured digit.

About Displacement and Velocity
Displacement is the directed change in position, while velocity is the rate of change of displacement and includes both magnitude and direction. The topic connects position-time and velocity-time graphs with average and instantaneous values, and distinguishes displacement from distance and velocity from speed.
