This problem has three parts.

Part $1$: A drone flies in a circular path around an object that is $90$ m east and $100$ m north of the drone operator. The drone is always $120$ m from the object.

Does the drone cross a north$-$south line through the operator's position?

$$ yes

$$ no

The drone's circular path has the radius of $120$ m which is larger than the $90$ m east distance to the object, so the drone will cross the north$-$south line through the operators position.

Explain why with one sentence: $q,$

Part $2$: Suppose the drone operator is facing the object. Is the drone ever "behind" the drone operator?

$$ yes

$$ no

The drone's circular path extends west of the operators position, meaning that the drone can be behind the operator at certain points during its path

Explain why with one sentence: $$
