During his research, Keenan finds that scientists have collected extensive data about climate change through
observations and theoretical models. He also learns about experiments that have been done to understand the
causes of climate change. He finds that evidence of climate change coincides directly with observed changes in the
sizes of glaciers and that there is also evidence to support climate change in the fields of archeology, botany, and
zoology Keenan has decided to call his presentation "The Theory of Climate Change." Is this an accurate title?
Yes, because theories are well-tested, widely accepted explanations that combine several hypotheses and
observations
Yes, because theories are a possible explanation of or an answer to a scientific question based on prior
knowledge or research
No, because theories are statements about how something behaves or functions in the natural world.
No, because theories are developed on the basis of experimentation, but they are not explanations

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.
