Explanation:
The final velocity of the bale have vertical and horizontal components. So, we have:
According to conservation of energy:
Since the plane is flying due east, we have 
. Replacing in (1):
Now, we calculate the momentum of the bale:
From pythagoras theorem we know that:
I think it is a hypothesis but i am not sure..
Answer:
first one :
the object will stay at the same speed and direction unless it is acted upon by an internal unbalanced force.
There are more herbivores than carnivores in a food chain....
"In a food chain, energy is passed from one link to another. When a herbivore eats, only a fraction of the energy becomes new body mass; the rest of the energy is lost as waste or used up by the herbivore itself to carry out its own life processes.
Therefore, a carnivore has to eat many herbivores to get sufficient energy to survive and grow."

Hopefully this helped :)
Whoa, hold up. When you have a hypothesis, you don't just let it sit there. You TEST it, to see if it holds water. When real information conflicts with a hypothesis, the hypothesis is simply discarded. Period.
If the tests seem to indicate that the hypothesis is true, then you have a THEORY.
Later, if new information or further tests conflict with the theory, (or the theory makes a prediction which fails), then the theory is changed. Depending on the complexity of the theory, the change may be anything from a small tweak to completely discarding it and starting over with a new hypothesis.
