Answer:
having half the swimmers first swim without fins and then with fins and having the other half swim first with fins and then without fins.
Explanation:
counterbalanced repeated measures is methodology of experimentation in which sample for experiment is divided into two parts equally. The first follows the condition of experiment in one series of step while other part follows the steps precisely opposite to that of first part. The objective of such methodology is to cover each condition of experimentation and nullify any error condition for every sample. It also makes sure that in series of steps, sequence does not affect the result.
Since in the above experiment Powel wants to counterbalancing first he needs to divide the sample of swimmer into two parts. Then both parts should follows opposite steps.
This can be best followed by
in first half sample
- test the speed of swimmer without fins
- then test the speed same set of swimmer without fin
- then see the discrepancy in the speed
second half sample
- test the speed of simmers with fins
- test their speed without fins.
- see the discrepancy in the speed
then compare the results of both set of sample. It will make sure that both half corroborate the same result, also sequence of with and without fins does not effect the result and produce biased result.
based on this option 3 is correct answer.
Answer:
A. Wet pipe System
Explanation:
For fires as a result of type A combustibles, any technique can be used to either starve, or smother the fire.
Consider the large size of the warehouse, since most fire protection systems can get the job done, a key determining factor will now be cost.
The Wet pipe or water sprinkler system is the most cost effective as it can be easily installed and maintained in large buildings. This is because it does not need other resources apart from running water which is already available in the building.
As a result, the wet pipe system is apt for such a warehouse.
Answer:
If "separate but equal" was constitutional in train car segregation

Assuming you're referring to the "Plessy vs Ferguson" court case. Then it was a landmark supreme court decision that was determining whether the "separate but equal" concept was constitutional in the U.S. This took place in 1896 and btw Ferguson won :)
