Answer:
Option C
Explanation:
Let the potential energy of rock A be represented as Pa
And the potential energy of rock B be represented as Pb
Pa = ma * g * h
Pb = mb * g*h
ma = 2 * mb
Thus, Pa = 2 mb * g*h
Pa/Pb = 2 mb * g*h/mb * g*h
Pa/Pb = 2
Pa = 2 * Pb
The energy pf rock A is two times the energy of rock B.
OR
Pb = Pa/2
Hence, option C is correct

Answer:
Explanation:
M. Pollan (2006) describes in his book “The omnivore's dilemma: A natural history of four meals” that human kind has fighted to get food as a basic need since ancient times. Nowadays, modernity and the intervention of science have made possible to have almost all kinds of foods available at the supermarket, while in the past, in order to have food, humans needed to depend on their skills to grow or hunt their meals, because as omnivores as we are, we eat basically everything (vegetable or animal) and need it in order to survive. Though, we like to think that we now have a great diversity available, Pollan (2006) describes in his book that this is only an illusion, created by capitalism, because basically must of our food is only corn in different presentations, at the end, only corn…he refers “ there are some forty-five thousand items in the average American supermarket and more than a quarter of them contain corn” (p.11)
