Answer:
Explanation:
As we know that average velocity is defined as the ratio of total displacement of the object and its time interval.
so here we can say
now we know that in one complete revolution the total displacement of the tip of the seconds hand is zero
because it will have same position after one complete revolution from where it starts
so here we can say that the average velocity will be zero
Answer:
This was my best estimation of the answers
