What is the velocity of hour hand and minute hand?
Step-by-step explanation: The minute hand of a clock covers 360 deg in 60 min or 6 deg/min. The hour hand of a clock covers 30 deg in 60 min or 0.5 deg/min.
What is the velocity of clock hands?
Hence, the angular velocity of the minute hand on a clock is π1800rad/s.
What is the angular velocity of an hour hand of a clock?
Answer. Answer: the answer is π/21600 rad /s.
What is the angular velocity of second hand and minute hand clock?
Since the minute hand of a clock completes a circular revolution in 60 minutes, the angular velocity of the minute hand is, ω=2π60×60=π1800=1.75×10-3rad⋅s-1 . Since the hour of a clock completes a circular revolution in 12 hours, the angular velocity of the hour hand is, ω=2π12×60×60=π21600=1.45×10-4rad⋅s-1.
What is the ratio of hours and minutes?
1 hour is equal to 60 minutes. So, 60 hours is equal to 60×60=3600 minutes.
What is the time between a 9 and 10 clock?
At what time between 9 and 10 o’clock will the hands of a watch be together? Explanation: To be together between 9 and 10 o’clock, the minute hand has to gain 45 min.
How do you find the speed of a clock hand?
You know that the minute hand makes 2pi in one minute (60 seconds). So angular velocity is equal: ω= 2*pi/60 = 1/60 pi. Velocity (perpendicular on the minute hand) is equal to :v=r x ω=0,055 * 1/60 pi.
How many RPM is a clock?
The speed of a clock’s second hand is exactly 1 RPM.
How often does the tip of an hour hand on a clock have the same velocity?
Answer: tip of an hour hand on a clock have the same velocity? once every minute; once every hour; once every 12 hours; once every 24 hours.
Is the angular velocity of rotation of hour hand?
Hour-hand of a watch completes one rotation in 12 hours, while earth completes one rotation in 24 hours. So angular velocity of hour-hand is double the angular velocity of the earth. This is because ω = 2 π T , where T is the time taken to complete one rotation and ω is the angular velocity.
