To measure a single page’s thickness, stack 100 pages together and measure the total thickness with a scale. Divide the total thickness by 100 to find the thickness of one page accurately.
Human perception has limitations in measuring motion due to factors like reaction time, inability to discern very rapid or very slow speeds accurately, and subjective interpretation of movement, which can lead to errors and imprecise measurements.
Very small lengths are measured accurately using precision instruments like micrometers or vernier calipers. These tools provide fine measurements by allowing the user to read very small divisions, ensuring high accuracy and minimal measurement error.
The slope of a distance-time graph represents the speed of an object. A steeper slope indicates a higher speed, while a flatter slope indicates a lower speed. A horizontal slope signifies that the object is stationary.
