2. Identify five more types of energy transformations that you see at home, at school, or outdoors. Make sure to name the action, such as turning on a light, as well as the two types of energy involved. Remember, for energy to be transformed, the type of energy before and after a task must be different. (10 points) As you look around you, make note of technology that is turned on and off. This indicates that some sort of energy is present before the switch is flipped. Also look at objects that move from one height to another, because that will involve kinetic and gravitational potential energy. Finally, look for actions that involve changes in temperature, sound, and light. Often these actions mean that energy is being transformed.

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.
