Cut a 7-inch-diameter a circle out of card stock. Draw a spiral on the circle as shown. Next, use the scissors
to cut along the lines you drew starting on the outside and ending in the center. Use the hole punch or
scissors to make a hole at the middle of the spiral and attach the thread with a knot. Tie the other end of
the thread loosely around the center of the stick so you can suspend the spiral in the air. Fill the pot with 2
inches of water. Heat the water until it boils, and then turn off the heat source. Let the pot sit for 4
minutes. Holding the ends of the stick with the spiral attached, position the bottom of the spiral right
above the top of the pot so it's not touching the water. Describe what happens.

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
