Explanation:
B. The theory might be modified if necessary.
C. Bernoulli will come up with another hypothesis.
D. Bernoulli's principle will be called "Bernoulli's hypothesis."
Bernoulli's principle is a theory given the name "principle" because _____.
A. it is actually more like a hypothesis
B. nearly all scientists agree that it is correct
C. it is one of the first things you would learn about in college
D. you can't provide evidence for it, but scientists know that it is correct
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.
