Cut a 7-inch-diameter 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.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.

He viscosities of several liquids are being compared. all the liquids are poured down a slope with equal path lengths. the liquid with the highest viscosity will

Two pans of a balance are 24.1 cm apart. the fulcrum of the balance has been shifted 1.33 cm away from the center by a dishonest shopkeeper. by what percentage is the true weight of the goods being marked up by the shopkeeper? assume the balance has negligible mass. answer in units of %.
