Stacy has a hollow can with an air tight plunger in the open
end that can slide in and out without friction. The inside has a compressed spring that presses on the plunger outward, and there is a vacuum on the inside of the can. On the outside, the pressure of the atmosphere or some other fluid can press on the plunger to move it deeper into the can. The spring constant of the spring is k = 85 N/m and when the external pressure changes by 410 Pa, the spring is compressed an additional 3.5 cm. What is the radius of the plunger? For your physical representation, draw a free-body-diagram of the forces acting on the plunger.

- A scuba diver makes a slow descent into the depths of the ocean. His vertical position with respect to a boat on the surface changes several times. He makes the first stop 9.0 m from the boat but has a problem with equalizing the pressure, so he ascends 3.0 m and then continues descending for another 12.0 m to the second stop. From there, he ascends 4 m and then descends for 18.0 m, ascends again for 7 m and descends again for 24.0 m, where he makes a stop, waiting for his buddy. Assuming the positive direction up to the surface, express his net vertical displacement vector in terms of the unit vector. What is his distance to the boat?arrow_forwardYou are applying for a position with a sea rescue unit and are taking the qualifying exam. One question on the exam is about the use of a diving bell. The diving bell is in the shape of a cylinder with a vertical length of L = 2.50 m. It is closed at the upper circular end and open at the lower circular end. The hell is lowered from air into seawater ( = 1.025 g/cm3) and kept in its upright orientation as it is lowered. The air in the bell is initially at temperature Ti = 20.0C. The bell, with two humans inside, is lowered to a depth (measured to the bottom of the bell) of 27.0 fathoms, or h = 49.4 m. At this depth the water temperature is Tf = 4.0C, and the bell is in thermal equilibrium with the water. The exam question asks you to compare two situations: (i) No additional gas is added to the interior of the bell as it is submerged. Therefore, water enters the open bottom of the bell and the volume of the enclosed air decreases. (ii) The bell is fitted with pressurized air tanks, which deliver high-pressure air into the interior of the bell to keep the level of water at the bottom edge of the bell. This choice requires money and effort to attach the tanks. The exam question asks: Which scenario is better?arrow_forwardWhen a tire pressure gauge is pressed against a tire valve, the air in the tire pushes against a plunger attached to a spring. Suppose the spring constant of the spring is k = 320 N/m and the bar indicator of the gauge extends 2.0 cm when the gauge is pressed against the tire valve. What force does the air in the tire apply to the spring? O 8.40 N 7.10 N O 6.40 N 7.50 Narrow_forward
- As a hiker in Glacier National Park, you are looking for a way to keep the bears from getting at your supply of food. You find a campground that is near an outcropping of ice from one of the glaciers. Part of the ice outcropping forms a 47.5° slope up to a vertical cliff. You decide that this is an ideal place to hang your food supply as the cliff is too tall for a bear to reach it. You put all of your food into a burlap sack, tie an unstretchable rope to the sack, and tie another bag full of rocks to the other end of the rope to act as an anchor. You currently have 19.5 kg of food left for the rest of your trip so you put 19.5 kg of rocks in the anchor bag to balance it out. What happens when you lower the food bag over the edge and let go of the anchor bag? The weight of the bags and the rope are negligible. The ice is smooth enough to be considered frictionless. O The anchor bag is on a slope so the food bag will drop, pulling the anchor bag up. The motion of the food bag cannot be…arrow_forwardCalculate the work done in breaking a mercury drop of radius 1 mm into one thousand droplets all of the same size.
