If enough experimental data supports a hypothesis, then it:
O A. Is proven 100% true.
O
B. Is falsified.
OC. Is accepted as true until prolan false.
OD. Becomes an Observational Law

Answers

Answer: C) Is accepted as true until proven false

==========================================================

Explanation:

We cannot prove the hypothesis to be 100% true because there might be data out there that we haven't accounted for, or some scenario that we haven't thought of yet. There's always going to be room for uncertainty and doubt. Keep in mind that such doubt does not necessarily mean that the theory is automatically false.

So all of this rules out choice A.

Choice B is ruled out as well because data supporting a hypothesis doesn't falsify the hypothesis. The term "falsify" means "to prove false" as you'd expect.

Choice C is the answer because the data seems to support the hypothesis and again we leave room for error. It's quite possible that in some unspecified date in the future, there are better methods of measurement to get a better sense of what's going on.

Choice D is ruled out because a law refers to something like the law of gravity. It's something you observe but it doesn't explain why something works. It doesn't provide the underlying mechanics of what's going on. We simply just report what we see which is exactly what an observation is.

As a river flows downhill carrying sediment, what happens when the river widens and slows down?
O A. The largest particles are deposited.
OB. The smallest particles are deposited.
C. Larger particles are picked up by the current.
D. Smaller particles are picked up by the current.

Answers

Answer: A

Explanation:

As a river flows downhill carrying sediment, the largest particles are deposited. The correct option is A.

The river loses the energy needed to move and carry heavier particles as its velocity drops. These larger particles start to settle when the water's force is no longer sufficient to hold them suspended.

Deposition or sedimentation are terms for this process. Due to their greater bulk and lack of buoyancy, the larger particles—such as boulders and pebbles—tend to settle first.

Smaller particles, such silt and clay, on the other hand, can float in the water for a longer time due to their higher buoyancy and lower mass.

Thus, the correct option is A.

Complete the sequence of numbers in this set. Explain the pattern.
7.5, 6.25, 5, ___, ___

Answers

The complete sequence will be:

7.5, 6.25, 5, 3.75, 2.50

This is an arithmetic sequence. The formula to find the nth term of an arithmetic sequence is:

= a + (n - 1)d

where,

a = first term = 7.5

n = number of terms

d = common difference = 6.25 - 7.5 = -1.25

Therefore, 4th term will be:

= a + (n - 1)d

where, n = 4

= a + (4 - 1)d

= a + 3d

= 7.5 + 3(-1.25)

= 7.5 - 3.75

4th term = 3.75

5th term will be:

= a + (n - 1)d

where, n = 5

= a + (5 - 1)d

= a + 4d

= 7.5 + 4(-1.25)

= 7.5 - 5.0

5th term = 2.5

In conclusion, the 4th and 5th terms are 3.75 and 2.5.

Testing Procedure: Interview some volunteers and ask them to describe their expectations about a given situation. Reproduce the situation below the volunteers' expectations and ask them to describe the emotions they felt when living the experience below expectations.

2. Hypothesis: The president-elect's party loses voters, because of the agenda the president is following that disappoints the voters he had.

Testing Procedure: Select a group of volunteers who voted for the president-elect and ask them to explain their level of satisfaction with the current government and how likely they are to vote for the president-elect's party candidates in midterm elections.

Explanation:

In a scientific experiment, the hypothesis is an assumption that the researcher makes about what will be researched, that is, the hypothesis is something that the researcher thinks happens and that he will prove that it is true or not through texts that make up the experiment. These tests will generate data, which the researcher will evaluate and be able to interpret, generating a conclusion.
