Answer:
hey mate,,, here is your answer...
Explanation:
speed= distance/ time
distance travelled by second hands= circumference of clock= 2πr
radius= length of second hand
= 8cm ( given )
time= 60s to complete circumference of clock
therefore, speed= 2*π*8/ 60
= 0.837cm/s
= 0.00837m/s
hope it helps you!!!
