Answer :
The angular velocity of the hour hand of a clock is 1.4x 10-4 rad/s
10-4 is 10 raised to -4
2 *pi /3200 ( because there are 12 hours and there are 60 minutes in an hour so i converted to minutes which was 60 * 60 =720 and then i had to multiply 720 *60=43200 to give the seconds in 12 hours)
1.45*10^ -4=0.000145
1.45*10^ -4=0.000145
