Which type of light is transmitted the most by eyeglasses with the coating? Which type of light is transmitted the least by eyeglasses with the special coating? Look carefully at the graphs. Does the data support the claim that the glasses block 100% of the UV and 50% of the IR light that hits the lenses?

Would it be a good idea for people to have this coating on eyeglasses that they wear every day? Explain.

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
