In scientific notation, numbers are expressed in________________?
Correct answer: A. Power of ten
- A. Power of ten
- B. Powers of two
- C. Reciprocal
- D. Decimal
Explanation
Scientific notation writes a number as a coefficient multiplied by a power of ten, such as 3.2 × 10^5. Students may choose d because the number is written in decimal form, but the defining feature is the power of ten.

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.
