Question

9 multiple choice 1 point which of the following is a derived unit? kg m/s m kelvin clear my selection

Explanation:

• A base unit is a fundamental unit (e.g., kg for mass, m for length, kelvin for temperature).
• A derived unit is formed by combining base units. \( \text{m/s} \) (meters per second) combines the base unit of length (m) and time (second, which is a base unit), so it is a derived unit for speed/velocity.

Answer:

B. m/s (assuming the options are labeled with A: kg, B: m/s, C: m, D: kelvin)
