support your answer with an example.
10. Which of the following is true for displacement?
(a) It cannot be zero.
(b) Its magnitude is greater than the distance travelled by the object.​

Answer 1

Answer:

• 2 -The maximum speed cover in per unit time called distance it's SI unit is metre

Answer 2

$\huge\mathcal\color{teal}{Answer :- }$

Yes, an object moving a certain distance can have zero total displacement. Displacement refers to the shortest distance between the initial and the final positions of the object. Even if an object moves through a considerable distance, if it eventually comes back to its initial position, the corresponding displacement of the object would be zero.
