Assignment 1 - Week 2 Due: 11:59pm on Friday, September 16, 2011 Note: To understand how points are awarded, read your instructor's Grading Policy . [ Switch to Standard Assignment View] 15.9 Note this is seawater. Problem 15.9 A research submarine has a 30.0 -diameter window 8.10 thick. The manufacturer says the window can withstand forces up to 1.00 × 10 6 . What is the submarine's maximum safe depth? Part A The pressure inside the submarine is maintained at 1.0 atm. ANSWER: 1400 Correct 15.7 Assume that this is an open vat. Problem 15.7 A 1.50 -diameter vat of liquid is 2.90 deep. The pressure at the bottom of the vat is 1.30 . Part A What is the mass of the liquid in the vat? ANSWER: 5480 Correct 15.32 This is a relatively short distance, so you can assume that the density of the air is constant. Problem 15.32 A gymnasium is 14.0 high. Part A By what percent is the air pressure at the floor greater than the air pressure at the ceiling?

Correct Pressure in the Ocean The pressure at 10 below the surface of the ocean is about 2.00 × 10 5 . Part A Which of the following statements is true? Hint A.1 How to approach the problem Since pressure is defined as force per unit area, the pressure at a given depth below the surface of the ocean is the normal force on a small area at that depth divided by that area. Thus, given the pressure at 10 you can determine the normal force on a unit area at that depth. Also recall that, in general, the pressure in a fluid varies with height, but it also depends
