Suppose new evidence is found about how Bernoulli's principle works. What is likely to happen?A. The evidence will be ignored.
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

Answers

Answer 1
Answer:

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.

Andrea is going to the golf course.The golf course charges a flat rate of $5.00 plus $1.50 per bucket of 50 golf balls. When she arrives,she is offered a discount rate of $.50 for a bucket of 50 golf balls plus the same flat rate. Andrea has $8.25 to speed. How many more bucket of golf balls will Andrea be able to get with the discount?A. 2 buckets
B. 4 buckets
C. 6 buckets
D. 8 buckets

Answers

B. 4 buckets more if she opts to avail the discount.

Given:
Flat rate = 5
Variable rate = 1.50

Option 1: Without discount
5 + 1.50x = 8.25
1.50x = 8.25 - 5
1.50x = 3.25
x = 3.25/1.5
x = 2.17 ⇒ 2 buckets

Option 2: with discount. $0.50 per bucket
5 + 0.50x = 8.25
0.50x = 8.25 - 5
0.50x = 3.25
x = 3.25/0.50
x = 6.50 buckets ⇒ 6 buckets.

Option 1:   2 buckets
Option 2:   6 buckets
Difference: 4 more buckets if she chose option 2. WITH DISCOUNT
c. 6 buckets

flat rate = $5
golf balls = $.50

Explanation:

A sample of metal has a mass of 16.63 g, and a volume of 7.94 mL. What is the density of this metal?

Answers

Answer:

The density of the metal is 2.094 g/mL.

Explanation :

Given,

mass of metal sample = 16.63 grams

Volume = 7.94 mL.

Density = ?

Density of the metal can be found by using the formula

Density = Mass/Volume

Substituting the values we get,

density = 16.63/7.94

by solving,

density = 2.094 g/mL.
