I will mark u as brainlist

Answer 1

Answer:

the speed of tip is 1/12m/sec

Answer 2

Answer:

for 15 min the hand travels through quarter of a circle

so distance= 3.14× r /2 ( where pi= 3.14 & r=5m)

and time=15 min

we know,

speed=distance/time

so substituting we get it speed

=0.0087266463 (or) 0.00873

whic can be written as

8.73×10^-7 m/sec

hope it helps :)
