• Introduce the issue(s) you are going to research in your paper. My research is going to be about stress.

what is the focal length of a convex mirror that produces an image that appears 15.0 cm behind the mirror when the object is 27.5 cm from the mirror?

Timothy Wilson, a psychology professor at the University of Virginia, studies the effect of "personal narratives" on people's behavior. For example, if the "story" you have about your academic ability is positive, you do better in school than if your "story" is negative. Something as simple as hearing older students describe overcoming challenges similar to yours can help you change your story and improve your performance.

A) Suppose you have reason to believe that students with a history of strong academic performance respond different than those with a history of modest performance. Describe how you would incorporate blocking to address this difference in response.
