30 points) Please show all your work Part I: Multiple Choice (5 points each) 1) Eltan, Jose and Raul are applying their knowledge of fluid dynamics to hurricanes, where air pressure can suddenly drop. Assume that the air pressure inside of a sealed house is 1.02 atm when a hurricane hits. The hurricane rapidly decreases the external air pressure to 0.910 atm. A square window in an outside wall of the house measures 2,02 m on each side. What net force (directed outwards) is exerted on this window? (1 atm = 1.01 x 10' Pa.) (A) 4.53 x 10" N (B) 5.14 x 10' N (C) 4.78 x 10 N (D) 5.37 x 10' N 2) Egor, David and Jasper connect a block to a light string attached to the bottom of a large container of water. The tension in the string is 3.0 N. The gravitational force from the earth on the block is 5.0 N. What is the block's volume? water block string (A) 2.0x10 4 m 3 (B) 3.0*10 4 m 3 (C) 5.0x10 4 m 3 (D) 8.0x10 4 m 3
