A great example of a physical boundary is a mountain. For example, the Pyrenees Mountains, which serve to separate France and Spain, are a physical boundary. So are the Ural Mountains which separate Europe and Asia. Along with mountains, oceans, seas, even deserts are examples of physical boundaries.
An average size apple weighs 6.4 ounces, which is equal to 180  grams. One apple contains approximately 91 calories and 3 grams of  dietary fiber.
Apples weight is dependent upon species, the amount of nutrients it receives and its size. The average apple is between 70 and 100 grams or 0.33 pound or 0.7 and 1N. This idea is ironic as it is often believed that it was a fallen apple that inspired Sir Isaac Newton's ideas about gravity.May 28, 2009.
