Yes

#### Explanation:

Displacement can be zero as we can assume a body travels a circular path and end up where it started so in this case the displacement is zero.

#### Explanation:

Displacement can be zero when an object travels eg. 1 metre to the left and then 1 metre to the right.

The object ends up back at its original position.

For a vector question, assume a direction to be positive and another to be negative.

In this scenario, I will take right as positive, and left as negative.

The object travels $- 1$ m to the left, and $+ 1$ m to the right.

Thus, displacement $- 1 + 1 = 0$ metres
