Biotic components are living things. The root word bio means life. When you say something is abiotic, it means non-living things. The prefix "a" means not or non.
<span>Sunlight and heat: Abiotic
Insects: Biotic
Rotting log: Biotic (This is considered biotic because it was a living thing.)
Bacteria: Biotic
Water: Abiotic
Rocks: Abiotic</span>
Answer:
what are the options for me
Answer:
Average speed: 0.5 m/s. Average velocity: 0
Explanation:
Average speed is given by:
where
d is the total distance covered (the length, of one lap of the track, so d = 400 m)
t is the time taken to cover that distance (so, t = 800 s)
Substituting,
Instead, average velocity is defined as
where this time,
d is the displacement, which is the vector connecting the starting point to the final point of the motion
t is still the time taken (800 s)
However, in this case the walker starts and finishes his trip at the same point: therefore, the displacement is zero (d=0), and this means that the average velocity is zero as well.
