C. After his boat runs out of gas, a boater considers dropping the motor into the water to create waves. Describe the resulting motion of the boat, and explain
why the boater's plan will not help him reach shore. Write two or three sentences
to explain your reasoning. (4 points)
G

Describe the path of a ray that approaches a mirror parallel to the principal axis.

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.)

How will the system respond to a temperature increase?
