Answer:
B. The theory might be modified if necessary.
B. nearly all scientists agree that it is correct
Explanation:
B. The theory might be modified if necessary.
The Bernoulli's principle relates the speed of fluid to their pressures. It simply states that when the speed of fluids increases there is a drop in pressure.
Supposing we find new evidence about how the principle works, the normal scientific thing to do is to modify the existing principle. New information and observations about a principle would only provide a modification to the existing one. An example is the Dalton's atomic theory, which was centered on the atom being the smallest indivisible particle: the theory was later modified when new ideas about the atom surface.
B. nearly all scientists agree that it is correct
Before a hypothesis is adopted to the context of scientific principle, the ideas behind it must have tested and must be repeatable. Different sources will verify the authenticity of such scientific claim to see if such can be adopted. Therefroe, nearly a large numbr of scientists must agree that it is correct.

As toothpick, pencil and log are all made up of same wood. So, this means that there will be same composition as amount of mass present in per unit volume will be the same.
Therefore, we can conclude that toothpick, pencil and log all of them will have same density.

Answer:
As the options for the question not given, lets try to answer this question generally.
Explanation:
A reliable source can be described as an authentic source which proves or declines an action, research etc.
The most reliable source for scientific information is scientific papers. This is because scientific papers are subjected to peer- review and hence been tested and validated. A peer-review can be described as a judgement or test made by a person on other peoples research, both of the people having equal caliber.
Answer:
It cites valid data because a reliable scientific source needs data to back up what they’re proving.
