Which factor when doubled would produce the greatest change in the centripetal force?
yaroslaw [1]
Let us consider the centripetal force equation,  
centripetal force F = mv² / r  
 f= force
 v= velocity
 m= mass
 r= radius.
 
 in all the factors only velocity has the power of 2. so when you double the velocity then it will become square of that. 
 if v= 2v , F = m4v² / r 
 so velocity is doubled it would produce the greatest change in the centripetal force.

How did the Earth get these different layers? Did the Earth always have very separate, distinct layers? Describe what happened.
Orlov [11]
Answer: The different layers are a result of lighter parts (such as the continental crust) settling at the surface level and heavier parts (such as iron and nickel in the core) settling in the middle. The layers separate by density, otherwise known as compositional layering. The earth did not always have these layers, as it had to undergo cooling to form some of them (like the continental crust).

An animal cell is growing and is active. The cell is going through which subphase of interphase?
valina [46]
<span>G1 stage is the first of four periods of the cell cycle that occur in eukaryotic cell division. In this piece of interphase, the cell orchestrates mRNA and proteins in readiness for resulting steps prompting mitosis. G1 stage closes when the cell moves into the S period of interphase.</span>
