The scientists can predict that the finches on the island are mostly insectivores.

This is a generalization because the scientist have taken 12 finches as a sample population and predicted the food habits of the Entire population of finches living on the island.

Explanation:

  • Generalization refers to deriving a conclusion about anything by observing any sample of it.
  • Usually generalizations are done while studying large populations.
  • We can define generalization as an act in which broad inferences are drawn by small observation.
  • It makes the qualitative evaluation easy when it is very difficult to study each an every individual of population.
  • In this experiment the scientists have observed only 12 out of many finches living on the island.
  • They observed only these 12 finches and inferred about the eating habits of all the finches in the island.
  • So, here a small observation of only 12 finches was used to give a broader inference about all the finches. Thus, it is a generalization.

Answer:

Every object has a total energy which is the sum of its kinetic and potential energy:

E = Ek + Ep

Kinetic energy is, as the name suggests, the energy of moving. It is given through the equation:

Ek = m • v^2 / 2

From here, we can see that Ek depends on the object's velocity; if v=0, then Ek will also be zero.

Potential energy is the energy an object has on a certain height:

Ep = m • g • h

Obviously, if the height is zero, then the Ep=0 too.

Another important thing to note is that E is always constant; if Ek increases (or decreases), Ep will decrease (or increase) so that their sum will always be a constant value.

If the bowling ball sits at the top of the 40 meters tall building, it has no velocity, it doesn't move, but it is located on a certain height.  

That means that, at the top of the building, the bowling ball has no kinetic energy:

E = Ep + Ek

- no velocity ---> Ek =0

E = Ep = mgh

Ep = 2 kg • 9.81 m/s^2 • 40 m

E = Ep = approximately 785 J

To conclude, at the top of the building Ep > Ek.

Now, the ball is falling, and it's halfway down and it's travelling 19.8 m/s. Now, its kinetic energy is:

Ek = m • v^2 / 2

Ek = 2 • 19.8^2 / 2

Ek = approximately 392 J

Now, since the ball is halfway down, that means that its height is 20 meters. So, its Ep is:

Ep = mgh

Ep = 2•9.81•20

We already stated that total energy is constant and that is the sum of Ep and Ek and that it is around 785 J. We could also find Ep:

Ep = E - Ek

Ep = 785 - 392

Whichever way we use to calculate, we'll get the value of approximately 392 J.

That means that, halfway down, Ep=Ek.

Since the ball is halfway down, that means that its Ep is half the value it was while at the top of the building. The other half is used on the ball's velocity producing kinetic energy. That's why these two are equal at the halfway down.

Just before it hits the ground, the bowling ball has no height, meaning it has no potential energy. That also means that its total energy is equal to its kinetic energy:

E = Ep + Ek

Ep = 0

E = Ek

We already said that the ball's total energy was around 785J, so its kinetic energy just before it hits the ground will be that exact value.
