Q. what are three components of attractiveness? Which of the three is most important to you? Why did you choose this factor? Consider, as you respond to your classmates' posts, how their responses have had an effect on your views about attractiveness.
Q. A flat sheet of crystalline quartz has a thickness of 3.7 cm. It is on top of a flat sheet of diamond that has a thickness of 2.6 cm. Light strikes the crystalline quartz perpendicularly and travels through it and then through the diamond. In the time it takes the light to travel through the two sheets, how far would it have traveled in a vacuum?
