During the day the land worms faster than the ocean. Air above the land also gets warmer, so it becomes less dense and rises. Meanwhile, air over the ocean is colder and denser, so it falls. A sea breeze develops from the movement of hot air rising and cold air sinking. This sea breeze is wind coming from the ocean into the land, which moves the branches of palm trees inlans as shown.
Which is the CORRECT description of the sequence of energy transformations occuring in this system?
A. electromagnetic energy is being transformed into thermal energy, and thermal energy is being transformed into mechanical energy, which is then transform into kinetic energy
B. electromagnetic energy is being transformed into thermal energy, and thermal energy is being transformed into kinetic energy, which is then transformed into mechanical energy
C. thermal energy is being transformed into electromagnetic energy, and electromagnetic energy is being transformed into mechanical energy, which is then transformed into kinetic energy
D. thermal energy is being transformed into electromagnetic energy, and electromagnetic energy is being transformed into kinetic energy, which is then transformed into mechanical energy

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.
