4. Complete Activity 7.4 (Page 73).
• Automobiles are fitted with a device that shows the distance travelled. Such a device is known as an odometer. A car is driven from Bhubaneshwar to New Delhi. The difference between the final reading and the initial reading of the odometer is 1850 km.
• Find the magnitude of the displacement between Bhubaneshwar and New Delhi by using the Road Map of India.
Answer:
Aim: To find the magnitude of the displacement between Bhubaneshwar and New Delhi by using the Road Map of India.
Materials Required: Road Map of India.
Procedure:
(i) Using a ruler measure the shortest possible distance between the cities Bhubaneshwar and Delhi.
(ii) Now compare the length obtained on the ruler with the scale given on the map to get the displacement.
Observations: The shortest distance between the two points gives us the displacement as shown by the red line below:
Conclusions: The displacement was measured to be around 1400 km. The displacement was less than the distance travelled by car.
