What is the angle of the reflected ray in the diagram above?​

The focal length of a relaxed human eye is approximately 1.7 cm. when we focus our eyes on a close up object, we can change the refractive power of the eye by about 16 diopters. (a) does the refractive power of our eyes increase or decrease by 16 diopters when we focus closely? explain. (b) calculate the focal length of the eye when we focus closely.

Which sections of the heating curve illustrate this process?

Does science support the idea that humans have influenced global warming? provide specific examples that show how two knowledgeable individuals with differing opinions might argue.
