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.
