Answer:
The velocity is given as -B sin(ωt) while the acceleration is given as -C cos(ωt).
Explanation:
As the complete question is not given here, a search for the question is made and the complete question is as given in the attached image.
From the given data the equation of displacement x as it varies with time is given as
Here
- A is the distance of the point at which it is released from the equilibrium position
- ω is the characteristic of the system measured in rad/sec.
Now in order to find the velocity, it is given as
Suppose that
So the equation becomes
So the velocity is given as -B sin(ωt).
Now the acceleration is given as
Suppose that
So the equation becomes
the acceleration is given as -C cos(ωt).
Professor Gustafson is developing a new intelligence test and wants to ensure the test has good inter-rater reliability. The following strategies will most directly help him achieve this goal- (C) <u>By </u><u>Allowing only trained researchers to grade the test, as they will have a good understanding of the proper way to score certain things and will be more likely to agree</u>
Explanation:
In order to test the inter-rater reliability of the new intelligence test professor Gustafson should:
- Trained researchers to grade the test because they have the knowledge of the test
- A trained researcher will be able to score the test result in a proper way
From the given option (a) allowing only a small subset of highly trained researchers to grade the test, because this ensures standardization of test conditions is not a valid option because the test is still in the developing stage so, the standardization of the test condition will not serve the purpose
Answer:
During its first century, psychology focused primarily on understanding and alleviating negative states. Today, however, thriving Western cultures have an opportunity to create a more positive psychology, focused on three pillars: emotion, characters, and groups.
