The number of significant figures in 5.400 is________________?
Correct answer: D. None
- A. 3
- B. 5
- C. 2
- D. None
Explanation
In 5.400, the two zeros after the decimal point are significant because they show measured precision, so the number has 4 significant figures. The digits are 5, 4, 0, and 0. Students may choose 3 by dropping the final zero, forgetting that trailing zeros after a decimal point are significant.

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.
