Thus the average velocity of mail truck is 
Answer:
Number 3
Explanation:
Unlike other numbers, this states that wind is "renewable". The choice 2 sounds a bit selfish, or not worded properly, I believe choice 3 is the answer. However, you are the judge of choosing to believe this or not.
Good luck!
Scientist identify the process in which gravity pulled materials together forming the planets in our solar system as accretion.
Accretion is the formation model of planets in our solar system in which gravity pulls materials together forming the planets.
This formation model accounts for the formation of the inner planets made of of dense material such as iron. These planets include Mercury, venus, earth etc.
As the gravity pulls in the more dense material, the less dense material such as ice, liquid and gas colect together to form the outer planets, which include Jupiter, Uranus, etc.
So, Scientist identify the process in which gravity pulled materials together forming the planets in our solar system as accretion.

Answer:
v = 1.6 m/s
Explanation:
Given that,
Distance, d = 72 m
Time taken, t = 45 s
We need to find their average velocity. Average velocity of an object is given by total distance divided by total time taken.

So, their average velocity is 1.6 m/s.
