Earth's rotation causes the sunrise phenomenon, and the speed and displacement of the minute hand of a clock can be calculated using formulas based on its length and rotational motion.
Earth's rotation causes the phenomena of sunrise due to its diurnal motion, where the Earth spins on its axis, making the Sun appear to rise in the east and set in the west each day. This motion is due to the rapid spinning of the Earth, not the Sun moving in space.
The speed at which the tip of the minute hand of a clock moves can be calculated using the formula: speed = distance/time. The length of the minute hand is 14 cm, and the time it takes for the hand to move around the clock face is 60 minutes (1 hour).
When the minute hand covers 360 degrees on the clock face, its displacement can be calculated using the formula for circumference: displacement = 2 π radius. Substituting the length of the minute hand as the radius will give you the displacement when it covers a full circle on the clock face.
