1.	Which of the following statements is incorrect? (i) Average velocity is path length divided by time interval. (ii) In general, speed is greater than the magnitude of the velocity. (iii) A particle moving in a given direction with a non-zero velocity can have zero speed. (iv) The magnitude of average velocity is the average speed.A. S2 and S3B. S1 and S4C. S1. S3 and S4D. All four statements
Answer» Correct Answer - C Average velocity `=("Displacement")/("Time interval")` A particle moving in a given direction with non-zero velocity cannot have zero speed. In general, average speed is not equal to magnitude of average velocity. However, it can be so if the motion is along a straight line without change in direction.
