Answer 1

Explanation:

magnitude of displacement will be 10 root 2

Answer 2

Answer:

Hi friend, 

Hi friend, Total distance covered 10m in 40sec

Hi friend, Total distance covered 10m in 40secTotal time taken= 2min 20sec= 140sec

Hi friend, Total distance covered 10m in 40secTotal time taken= 2min 20sec= 140secTotal round completed = 140/40=3.5 rounds 

Hi friend, Total distance covered 10m in 40secTotal time taken= 2min 20sec= 140secTotal round completed = 140/40=3.5 rounds So If an object moves from A to D, the shortest path will be from A to C. So displacement is AC, that we will find by phythogoras theorem.

Hi friend, Total distance covered 10m in 40secTotal time taken= 2min 20sec= 140secTotal round completed = 140/40=3.5 rounds So If an object moves from A to D, the shortest path will be from A to C. So displacement is AC, that we will find by phythogoras theorem.AC2= AB2 +BC2 

Hi friend, Total distance covered 10m in 40secTotal time taken= 2min 20sec= 140secTotal round completed = 140/40=3.5 rounds So If an object moves from A to D, the shortest path will be from A to C. So displacement is AC, that we will find by phythogoras theorem.AC2= AB2 +BC2 AC2= (10)2 +(10)2

So displacement is AC, that we will find by phythogoras theorem.AC2= AB2 +BC2 AC2= (10)2 +(10)2AC2= 100+100
