-List ten different waves that you encounter in everyday life. Be specific, don't just say "sound waves," but say "the sound waves generated by my cat meowing."

-For each of the waves in your list, specify whether it is a "transverse" or "longitudinal" wave

(I just need random everyday examples)

Will you chech and finish these for me, because i am stumped with them.

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.

If a balloon is taken outside on a very cold day, what will occur?
