> Question 4 of 8 > © Macmillan Learning A 0.573 kg metal cylinder is placed inside the top of a plastic tube, the lower end of which is sealed off by an adjustable plunger. The cylinder comes to rest some distance above the plunger. The plastic tube has an inner radius of 5.37 mm and is frictionless. Neither the plunger nor the metal cylinder allow any air to flow around them. If the plunger is suddenly pushed upwards, increasing the pressure between the plunger and the metal cylinder by a factor of 2.31, what is the initial acceleration a of the metal cylinder? Assume the pressure outside of the tube is 1.00 atm and that the top of the tube is open to the air. a = 27.29 Incorrect m/s² 100 > Attempt 3

You were told not to stand so close to a rapidly moving train because you might get sucked under it. What do you think will likely happen to you? Select one: The moving train could actually suck anybody closer to it. The moving train could be out of its way and will hit you. Greater pressure behind you will push you toward the moving train. Greater pressure between you and the train will pull you toward the train.
