How long does it take for the minute hand on a clock to pass through 3π2 radians?
Time taken by the minute hand of a watch in tracing 4 right angles or an angle equal to 2 it radians = 1 hour.
How many radians does the minute hand?
1 Approved Answer The minute hand when it moves around the clock will have traveled 360 degrees or 2*pi radians, travelling 2*pi radians in 60 minutes. So 6 minutes out of 60 minutes is 1/10. So… he minute hand travels 1/10 of 2*pi radians (multiply 1/10 and 2*pi to get your answer).
How many radians does the minute hand of a clock turn in 3 hours?
SOLUTION: in 3 hours, through how many radians does the minute hand of the clock move? Question 1078480: in 3 hours, through how many radians does the minute hand of the clock move? = 6*3.14 radians (approximately).
How many radians does the minute hand of a clock moves in 45 minutes?
The minute hand moves 360 degrees in an hour (60 minutes). That’s 6 degrees per minute. So 45 degrees would be seven and a half minutes.
How many radians does the hour hand of a clock turn in 2 hours?
Answer Expert Verified Since a clock is a circle, it is equal to 2pi radians which is also 360 degrees. One full rotation takes 12 hours to complete. So in a single hour, the hour hand moves 360/12 degrees which equates to 30 degrees per hour. So half and hour, or 30 minutes, is equivalent to 15 degrees.
How many radians does the hour hand of a clock turn in 20 minutes?
So each hour represents 30°. The minute hand moves 60s per minute and a full rotation is 360° so: 360/60 = 6° per minute. So in 20 minutes the minute hand will be 6 * 20 = 120° and the hour hand will be 120/12 = 10°.
How many radians does the earth turn in 1 hour?
This rotation is a full 360 . So, in one hour, the earth turns 15 . Every four minutes, the earth has turned one degree.
How many radians are in an hour?
π/12 radians
How many radians are in a clock?
In polar coordinates, angles are measured counter-clockwise from the positive x-axis. Thus, this clock starts at midnight with both hands pointing to what is normally the 3 o’clock position – and then from there it goes backwards! A full circle is 2π radians, so each hour is 2π /12 = π / 6 radians.
How do you convert time into radians?
Convert Seconds Of Time to Radians 1 Second of time (astronomical) is equal to 1 turn/86400. In radians (SI unit) 1 second of time is π/43200 rad.
