To determine which of the given quantities is a scalar, let's first understand what a scalar quantity is. A scalar quantity has only magnitude and no specific direction. Examples of scalar quantities include speed, distance, mass, and temperature.
Now, let's examine each option:
A. 14 m/s² east
- This quantity includes both magnitude (14 m/s²) and a direction (east), making it a vector quantity.
B. 25 cm/s to the left
- This quantity includes both magnitude (25 cm/s) and a direction (to the left), making it a vector quantity.
C. 10 miles/hr south
- This quantity includes both magnitude (10 miles/hr) and a direction (south), making it a vector quantity.
D. 14 m/s
- This quantity includes only the magnitude (14 m/s) without specifying any direction, making it a scalar quantity.
Based on the definitions and the given options, the correct answer is:
D. 14 m/s
