How are donkeys created?
Donkeys are descended from the African wild ass. They were likely first bred around 5,000 years ago in Egypt or Mesopotamia. A mule, on the other hand, is a hybrid animal. Mule foals are the offspring of female horses and male donkeys (a “jack” — hence the word “jackass”).
What is the history of the donkey?
More specifically, donkeys come from the Somali and Nubian wild asses. The first captivity of the wild ass was in Egypt and western Asia dated back as early as 2800 B.C. to 2500 B.C. It was not until 1000 B.C. that the donkey became the common means of transportation through Egypt, Asia , and parts of Europe.
Is gravity a push or a pull?

What are the 3 examples of acceleration?
Examples
- An object was moving north at 10 meters per second.
- An apple is falling down.
- Jane is walking east at 3 kilometers per hour.
- Tom was walking east at 3 kilometers per hour.
- Sally was walking east at 3 kilometers per hour.
- Acceleration due to gravity.
Is push or pull a balanced force?
An object’s motion can be changed by unbalanced forces. Balanced forces do not change the motion of an object. The motion of an object will not change if the forces pushing or pulling the object are balanced. An object that is sitting still will stay still if the forces acting on it are balanced.
What happens when you push against a wall?
According to Newton’s third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.
Which could be an example of a balanced force?
Floating in water. Objects float in water when their weight is balanced by the upthrust from the water. The object will sink until the weight of the water it pushes out of the way is the same as the weight of the object.
