Newton's law of gravity defines the attractive force between all objects that possess mass. Understanding the law of gravity offers profound insights into the way our universe functions. Newton, upon observing an apple fall from a tree, began to think along the following lines: The apple is accelerated, since its velocity changes from zero as it is hanging on the tree and moves toward the ground. Thus, by Newton's 2nd Law there must be a force that acts on the apple to cause this acceleration. Let's call this force "gravity", and the associated acceleration the "acceleration due to gravity". Then imagine the apple tree is twice as high. Again, we expect the apple to be accelerated toward the ground, so this suggests that this force that we call gravity reaches to the top of the tallest apple tree. <span>Newton knew that the force which caused the apple's acceleration (gravity) must be dependent upon the mass of the apple. And since the force acting to cause the apple's downward acceleration also causes the earth's upward acceleration (Newton's third law), that force must also depend upon the mass of the earth. </span>
Answer:
depending on which dog, depending on the color of the parents, maybe it is such that one of the parents is white and the other is red and they will have a black puppy
Answer:
The correct answer is - photosystem II.
Explanation:
Photosystem II is a specialized protein complex that traps the light energy from the sunlight and utilizes it to transfer electrons to Pq from water, which ultimately helps in the production of oxygen.
As we know photosystem II helps in production and cyanobacteria were the primitive organism it is considered as after the development of the photosystem II, cyanobacteria begin the aerobic life.
Thus, the correct answer is - Photosystem II.
