What is the rotational speed of a wall clock that has a sweeping hand that is Cm long?
The angular speed (expressed, for example, in radians/second, degrees/minute, etc.) doesn't depend on the length of the hand. To calculate this, just divide a full circumference (= 360 degrees, or 2 x pi if you use radians) by the time it takes to turn around once.
To calculate the linear speed, multiply the radius by 2 x pi, to get the circumference. Then divide that by the time it takes to turn around once. For example, for the minute hand you would divide by 1 hour.

Infer how distance and speed in the motions of analog clock parts are used to measure time?
In an analog clock, the movement of the hour, minute, and second hands is based on a circular motion around the clock face. Each hand moves at a specific speed: the second hand completes a full rotation every 60 seconds, the minute hand every 60 minutes, and the hour hand every 12 hours. The distance traveled by each hand correlates with the time elapsed, as the constant speed of the hands allows for consistent measurement of time intervals. Thus, the combination of distance covered and the speed of movement enables accurate timekeeping.
Which hand on a clock is the minute hand?
It is the long hand.
What is the rotational speed of the second hand on a clock that measures the seconds?
It takes 1 minute to rotate 1 time.
What is the speed of a clock hand?
The speed of a clock hand depends on what the clock hand indicates the second hand is 2pi per 60seconds, the minute hand is 2pi per 3600 seconds and the hour hand is 2pi per 216000 seconds.
What is the difference between oscillating and rotational motion?
Rotational motion is motion which emulates that of the minute hand of a clock. Oscillating motion is motion which emulates that of the pendulum.
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.
Does a wall clock have a magnet in it?
Some wall clocks may have a magnet in them, particularly if they have a sweeping second hand that moves in a smooth motion. The magnet helps regulate the movement of the clock hands for more accurate timekeeping.
How do you write a calculation for the speed of a minute hand on a clock?
its formula is 2pi r
Is clock speed is measured in bytes?
No, clock speed is not measured in bytes. Clock speed is a measure of how many cycles a computer's CPU can perform in a second, typically measured in Hertz (Hz) or gigahertz (GHz). Bytes, on the other hand, measure data size or storage capacity.
What is the speed of a clock's minute hand?
it moves at one click every 60 seconds

Which hand is the hour hand on a clock?
The short hand is the hour hand on a clock.
What is the Little hand on the clock?
The little hand on the clock is known as the hour hand.
If the length of the minute hand of a clock is 5cm how can you calculate its speed?
The minute hand traces its path around the clock once in an hour. The distance travelled by the tip of the hand in this time is 2 x pi x 5cm.The speed is then 10pi cm/hour, which is 8.73 x 10-5 ms-1.
