An eagle flying 10 meters per second swoops down to the ground to catch a snake speed velocity or acceleration

Velocity because it has both magnitude (10m/s) and direction (to the ground).

Explanation:

Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.

Mathematically, velocity is given by the equation;

In this scenario, an eagle flying 10 meters per second swoops down to the ground to catch a snake. Therefore, this is an example of velocity.

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
