Answer:
The first trophic level of the food chain has the most energy.
The officer is describing the motorcycle's acceleration
That is, he's describing how the motorcycle's velocity changes when compared to the time. That's the formula for calculating the average acceleration of any body.

Actually Welcome to the Concept of the kinematics of a body.
Since, we know that Velocity = Distance / time
hence, V = 20/5 = 4 m/s
hence the velocity of the RC car is 4 m/s westwards direction.
Answer:
Applying enough force in one direction to move the object, making kinetic energy.
Explanation:
Simpleness
These stars fuse helium into carbon just like the sun.
