For your cabin in the wilderness, you decide to build a primitive refrigerator out of styrofoam, planning to keep the interior cool with a block of ice that has an initial mass of 27.0 kg . the box has dimensions of 0.500 m ×0.850 m ×0.500 m . water from melting ice collects in the bottom of the box. suppose the ice block is at 0.00 ∘c and the outside temperature is 17.0 ∘c .
if the top of the empty box is never opened and you want the interior of the box to remain at 7.00 ∘c for exactly one week, until all the ice melts, what must be the thickness of the styrofoam?

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.
