Activity 8.4 Class 9 Science Chapter 8 Motion
What activity asks?
The activity asks us to find the magnitude of displacement between Bhuvneshwar and New Delhi.
Answer:
The magnitude of displacement between Bhuvneshwar and New Delhi is around 1400 km.
Explanation:
The magnitude of displacement is the shortest possible distance between two points. The roads of a city are not linear and change its shape as per terrain. For example, while climbing a mountainous region road is circular and so on.
The only possible shortest distance is through the air.
We can get the magnitude of displacement by placing a thread between the point on a road map and compare it with the scale given on the map.
Here we get around 1400km only. While by road distance it is 1850km.
Inference:
The city shows that magnitude of displacement between two points is either equal to or shorter than its distance.
