Answer:
The correct answer is - 0 m/s.
Explanation:
In this position-time graph or distance-time graph, there are three different part that shows three different velocities one in increasing as it moves from a lower position in relative to time and one is stationary and the third is decreasing.
'Straight lines' on a distance-time graph suggest that the movement of the object is constant. During 'Part B' of the journey the object travels 0m in 3s. It is stationary for 3 seconds so the velocity will be zero as well.
Answer:
If for example food becomes scares for a group of birds they must now eat something else. these birds have two different beaks on large for the food currently going becoming spars and the other just small enough for them to eat the smaller nuts and survive.
