The second hand will have moved 12° in 5 seconds, the minute hand 1° in 5 seconds, and the hour hand would move almost 0.0167 (0.016 and the six is recurring).

Why is angular displacement a vector quantity?
Angular displacement is a vector quantity because it has both magnitude and direction. The direction of angular displacement is determined by the axis of rotation and follows the right-hand rule, while the magnitude is given by the angle of rotation. As a vector, angular displacement can be added, subtracted, and resolved into components, making it useful in calculations that involve rotational motion.
What is angular speed of second hand mint hand and hour hand calculated angular velocity?
Second hand . . . 360 degrees per minuteMinute hand . . . 360 degrees per hourHour hand . . . 360 degrees per 12 hours = 30 degrees per hour
How many seconds have passed when the second hand is at 4?
If the second hand began at 12, 1200 seconds would pass in this period, or 20 minutes.
How do you find the angular velocity of second hand of a watch?
Angular velocity has units of (angle per time), usually stated in radians per second. (1 whole revolution = 2 pi radians) Assuming the watch is operating properly, the second hand turns once per minute. 1 rev/minute = (2 pi) / (60 seconds) = pi/30radians per second. This is usually good enough for most physicists, but if they demand a number, it's easy to work it out: pi = 3.14159 (rounded) Angular velocity = pi/30 = 0.10472 radians per second. Or if you really want the physicist to take notice, tell him "104.72 milliradians per second".
Why is the third hand on the watch called a second hand?
It is used to measure the number of seconds in a minute (60 seconds).
What is the angular speed of the minute hand in radian per second?
Angular speed = 2*pi radians per 60 seconds = pi/30 radians per second.
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 angular speed of the second hand?
6 degrees/second
What is the angular speed of a second hand of a watch?
150radians/sec
What motion is a second hand watch moves through a complete circle every minute?
That motion is called angular motion. The angular speed of the second hand is 2pi radians per minute.
What is angular speed of second hand mint hand and hour hand calculated angular velocity?
Second hand . . . 360 degrees per minuteMinute hand . . . 360 degrees per hourHour hand . . . 360 degrees per 12 hours = 30 degrees per hour
Why is the second hand on a clock called a second hand?
Because it counts seconds.
The second hand on a watch moves through a complete circle every minute The motion of the second hand on a watch is best described as?
Angular motion.
Why is the third hand on the clock called a second hand?
Because it points at the seconds? hours minutes seconds
