The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature. Whatever really happened, Newton realized that some force must be acting on falling objects like apples because otherwise they would not start moving from rest.
Explanation:
At the center its weight is zero. Or you can argue by symmetry: if the weight is not zero, in what direction would it act?
That statement is FALSE
The correct statement would be : In a function, EVERY element of the range must map to exactly one element of the domain

Soil form as rock is broken down by weathering and mixes with other materials on surface. soil is constantly being formed wherever bedrock is exposed. over time soil develops layers called horizons. a soil horizon is a layer of a soil that differs in color and texture from the layers above or below it.
