Answer:
B. PEi + KEi = PEf + KEf
Explanation:
It is given that
A leaf falling to the ground before hitting the ground has an initial total energy of PEi + KEi.
And the total final energy of the leaf after it hits the ground is PEf + KEf .
Since there is no air resistance, therefore the total energy is conserved.
According to the conservation of law of conservation of energy, energy is neither created nor it is destroyed. The energy is always conserved. The initial energy will be equal to the final energy.
Thus the total energy of the leaf before hitting the ground and after hitting the ground will be equal.
Thus initial energy is equal to the final energy.
Hence the answer is ---
B. PEi + KEi = PEf + KEf
Answer:
a coordination problem.
Explanation:
Based on the information provided within the question it seems that the collective dilemma that these groups are facing is a coordination problem. This is because each group is going their separate way in order to achieve the same goal. What they need to do is coordinate their actions and work together to achieve their goal. Union creates strength and allows them to have a better chance at achieving change.
