The second (right-hand) column contains reasons or explanations of the statements given in the first (left-hand) column.
well, 360 degrees in a minute. So 360 * 5 = 1800 degrees
At exactly 1 o'clock, the hour hand will be at an angle of 30 degrees, and the minute and second hands will be at an angle of 0 degrees.
First person shakes hands 19 times, second person 18 etc, a total of 190.
The hour hand would be at 195 degrees and the minute hand at 180 degrees.
That motion is called angular motion. The angular speed of the second hand is 2pi radians per minute.

Angular speed = 2*pi radians per 60 seconds = pi/30 radians per second.
No, angular speed refers to how fast an object is rotating around an axis at a given moment, usually measured in radians per second. Angular acceleration, on the other hand, describes how quickly the angular speed of an object is changing, or how fast the rotation is accelerating or decelerating.
The angular velocity of the second hand of a clock is pi/30 radians per second.
-- 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.
The angular velocity of the hour hand of length 1cm of a watch depends on the time unit and geometry of the watch. It can be calculated by dividing the angular displacement of the hour hand by time. One full rotation of the hour hand in 12 hours gives the angular velocity in radians per hour.
The second hand moves 1/60th of a full rotation per second, this is equivalent to 2π/60 radians per second this is known as the objects angular velocity. the equation linking linear velocity and angular velocity is v=rω where v=linear velocity, ω=angular velocity and r=radius and so we must substitute our values in. v=(15/1000)(π/30)=0.00157 m/s which is 1.57mm/s. notice instead of just putting 15 for the radius, i did 15/1000 in order to change it from millimetres to metres, this gave me the linear velocity in m/s.
Angular velocity refers to the rate of change of angular displacement with respect to time and has both magnitude and direction. Angular speed, on the other hand, refers to the rate of change of angular displacement with respect to time but does not consider direction and is scalar in nature. In simpler terms, angular velocity includes direction while angular speed does not.
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".
