Answer 1

speed of second hand is 0.35π or 1.09

Answer 2

Hey there !!!!!

_______________________________________________________

Tip of seconds hand of the clock covers the circumference of the clock which is circular in shape.

So distance covered =2πR = 2π*10.5 = 66cm =66/100 =0.66m

Speed =distance/time = 0.66/60 = 0.11 m/s
