Explanation:
True
Average speed is the ratio of total distance traveled to the total time taken and average velocity is total displacement to the total time.
And we know distance is either equal to or greater than displacement so we can say that for equal time interval magnitude of average velocity can never be greater than average speed.
your answer is *A. *second harmonic.
