Question

Angular weloily = ( frac{text { Angule dixplacement }}{text { Tune }} ) The nound cotates ( 2 times pi ) radians
in 60 seronds
( therefore ) Angmene welointy ( =frac{1 times pi text { radians }}{frac{60}{30} text { seconds }} ) ( =frac{pi}{30} operatorname{rad} s^{-1} )
( = ) option ( (d) )

# 39 The angular velocity of seconds hand of a watch is (a) 60 i rad s-1 (b) o rad s-1 (c) 40 rad s-1 (d) rad s-1
