Suppose you wanted to research the following hypothesis: Children who walk to school are healthier than children who ride the bus. What research strategy would you use to test this hypothesis? Why? Identify specific principles of good scientific research.

Answers

Answer 1

To test this hypothesis I would select an even number of children (20 children, for example) and divide them into two groups. Each group would undergo a series of medical examinations to assess everyone's health (it is important that all children have a healthy body). Then each group would receive a "mission", the mission of group A would be to go to school only by bus for 6 months, the mission of group B would be to go to school just walking for their months. After this period of time, the children would be submitted to the same exams so that we could assess changes in the health of each one of them.

One of the most important principles of scientific research refers to the establishment of an experiment so that it is possible to collect data that can confirm or cancel a hypothesis. As we can see in the example above, this principle was applied, since a 6-month experiment was established, which will provide data, so that it is possible to confirm or deny the hypothesis that children who walk to school are healthier than those who go to school by bus.

b. Dr. King is in a rally as a protest.
c. Dr. King is using his freedom of speech.
d. Dr. King is using the freedom of the press.

Answers

Answer:

Explanation:

This question is a hard one to answer. There are 2 right answers and you have to pick one. The two are

1. Right of freedom of assembly

2. He's in a rally as a protest.

He emphasized when he talked about his activities that he was concerned about exercising the right of assembly. He made sure that his followers understood that it had to be peaceful even when the opposition was not.

He used rallies as his focal point on how to exercise his protests. They had to be peaceful.

But what answer do you give? I would say that it is A which is the freedom that he was using and which could not be disputed if it was peaceful. B talks about method, but I think the Principle is more important.

Answer:

Explanation:

Freedom of peaceful assembly, sometimes used interchangeably with the freedom of association, is the individual right or ability of people to come together and collectively express, promote, pursue, and defend their collective or shared ideas.

Using 3 seismograms, epicenters can be calculated using the difference in arrival times of:

Question 4 options:

Microwaves and Radio Waves

Ocean Waves and Sound Waves

R-Waves and T-Waves

P-Waves and S-Waves

Answers

Primary waves and secondary waves! LOve you hope it helpsExplanation:

P-Wave and S-Wave arrival time differences can be used to calculate epicenters. As a result, choice (D) is the correct one.

What are P-waves and S-waves?

Earthquakes produce two types of waves that pass through solid rock:

The rock vibrates in the direction of propagation in P or compressional waves. P waves leave the earthquake first and go the furthest. Rock vibrates in the direction of wave propagation in S or shear waves.

In rock, S waves typically move at a pace of roughly 60% that of P waves, and they always come after the latter.

For instance, sound waves are P waves that have a frequency high enough to be audible to the human ear. An S wave is demonstrated by wriggling or shaking a rope that is fastened at one or both ends.

Hence, option (D) is accurate.
