এক মিনিটে একটি দেওয়াল ঘড়ির সেকেন্ড কাঁটার সরণ কত মিটার?
To solve this problem, let's analyze it step-by-step:

Step-1: The second hand of a wall clock completes one full circle every minute.

Step-2: The second hand travels along the circumference of the clock, but the displacement is the straight-line distance between the starting point and the ending point.

Step-3: After completing one full circle (360 degrees) in one minute, the second hand returns to its starting point.

Step-4: Since the starting point and the ending point are the same, the displacement is zero.

#Answer: 0
