Lucas left a metal bowl and a wooden bowl outside overnight. The next morning, he picked up the bowls to bring them inside. He noticed that the metal bowl felt much cooler than the wooden bowl. His father explained that both bowls were actually the same temperature. Which statement best describes why the metal bowl felt cooler even though the bowls were the same temperature?
A
Wood transfers heat away from the skin by convection, creating the sensation of warmth.

B
Metal removes moisture from the skin by absorption, creating the sensation of coolness.

C
Metal transfers heat away from the skin by conduction, creating the sensation of coolness.

D
Wood transfers heat to the skin by radiation, creating the sensation of w

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.)
