select the correct answer. what does the expression “75 meters per second southeast” best describe? a. acceleration b. distance c. speed d. velocity

Answer

Brief Explanations:

Speed is a scalar quantity with only magnitude (like 75 meters per second). Velocity is a vector quantity with both magnitude and direction. Here, "75 meters per second southeast" has both magnitude (75 m/s) and direction (southeast), so it describes velocity. Acceleration is the rate of change of velocity. Distance is a scalar representing length of path.

Answer:

D. velocity
