<span>Psychological researchers must debrief human test subjects </span><span>at the end of every experiment.
The current code of ethics in p</span>sychological research states that researchers absolutely must debrief human test subjects at the end of every study regardless or whether or not harm or deception was involved.
Debriefing a subject after a study is an essential opportunity for the researcher to explain the purpose and aim of the study to the subject, make sure the subject is not harmed or mentally disturbed, clarify why deception was used (if deception was involved) and overall, to clarify any questions or doubts the subject might have.
Answer:
Explanation:
First, we have to calculate the gel's column height using the cylinder's volume, as follows:
Then, as the pressure given at the bottom of the tank is the sum of the surface pressure and the gel's column pressure, we need to calculate only the gel's column pressure:
ft of water is a unit of pressure, but we need to convert it to atm and then to Pa, in order to calculate our results in the correct units. Therefore, the conversion factor is:
1 ft of water (4°C) = 0.0295 atm
Now, to calculate the specific gravity, we need to find first the gel's density:
The specific gravity of the gel is 3.75.
I think it’s D because I have heard in previous tests that it ruins the landscapes
Answer:
A. Is the one that the experimenter manipulates directly
Explanation:
The independent variable is the one that is manipulated during an experiment by the experimenter.
The dependent variable is the one that is effected by the independent variable in an experiment.
<h2>The body will move towards the center .</h2>
Explanation:
When the object moves in a circle , the centripetal force is applied towards the center .
Due to inertia of motion , equal and opposite force is developed , acting outwards from center of circle .
This force is called centrifugal force , which balances the centripetal force and the body remains in a circle .
If there is no inertia , this outward force will be zero . thus the body will move towards the center due to its one force called centripetal force .
