Answer 1

Answer:

12:1

Step-by-step explanation:

hope it is help you

Answer 2

ω = 2π/T { where T is time taken by it to complete one revolution in sec }

ω of minute hand of watch = 2π/ 3600sec

{ minute hand of watch takes 60min to complete one revolution which is equal to 3600 sec}

ω of hour hand = 2π/ 43200

{ hour hand takes 12 hrs to complete one revolution which is equal to 43200 sec }

ω of minute hand : ω of hour hand

= (2π/3600) : (2π/43200)

= (1/3600) : (1/43200) = 43200 : 3600 = 12 : 1
