What is the angular velocity in radians per second of the second hand of a clock?
The angular velocity of the second hand of a clock is pi/30 radians per second.
What is the speed of a clock's second hand?
A clock's second hand makes one complete revolution each minute. Thus, by definition, it is rotating at one revolution per minute or one RPM. That's its "rotational velocity" and it is the same no matter how big or small the clock might be. The actual velocity that the tip of the second hand might trace out as it revolves around the center of the clock will vary with the length of the second hand. The longer the hand, the faster the tip moves around the circumference.
Which has more momentum a second hand on a clock or a minute hand on a clock?
the second hand
What are the magnitude of the angular velocity and the angular accelaration of the second hand of a clock?
-- The angular velocity isone revolution/minute = 360 degrees/minute = 6 degrees/second .(2 pi) radians/minute = pi/30 radians per second . -- If the clock is working properly ... not starting, stopping, speeding up, orslowing down ... then the angular acceleration of any of its hands is zero.
Is the motion of the tip of the second hand of a clock equal to the motion of the entire second hand of the clock?
What do you mean with "motion of the entire second hand"? Please bear in mind that different parts of the hand move at different speeds. The closest thing to a "motion of the entire second hand" might be the motion of its center of mass. In this case, the answer is clearly "no". The center of mass is closer to the center than the tip, and moves slower.
What is the second hand on a clock called?
Sometimes, it is called a sweep hand, but the hands on a clock usually are called hour, minute, and second.
How many times does the second hand on a clock circle the clock in seven hours?
The second hand on the clock circles 420 times in 7 hours.
Why is the second hand on a clock called a second hand?
Because it counts seconds.
How do you find the acceleration of a second hand?
The second hand of a clock completes one full rotation in 60 seconds. Given that acceleration is the change in velocity over time, the second hand experiences a constant angular acceleration of 0.1 rad/s^2 as it moves in a circular path.
Why is the third hand on the clock called a second hand?
Because it points at the seconds? hours minutes seconds
What is the angular velocity of the hour hand of a clock?
Angular velocity = angle covered / time taken Hence angular velocity of the hour hand = 2pi/ 12*3600 = 1.4 x 10-4 rad/s
What is the least count of clock if it has hours hand minutr hand and second hand?
its least count will be one second
