Question

8.

What quantities are needed to describe the position of a water fountain relative to where you are standing?

Answer 1

D. the distance and direction to the water fountain

Step-by-step explanation:

To describe the position of a water fountain relative to where one is standing, the distance and direction to the water fountain must be known.

This quantity is known as the displacement.

• Displacement is a vector quantity with both magnitude and direction.
• To specify the magnitude of a displacement, we use the length of path and in this case the height or sometimes the distance.
• The direction attribute distinguishes distance from displacement
• The perfect quantity to solve this problem is the displacement and it specifies the distance of the path and the direction traveled.
