1 Physics 123 section 1 Fall 2013 Instructor: Dallin S. Durfee Exam #1, Sept 27 - Oct 1 2 PART EXAM DO NOT WRITE ON THIS EXAM Allowed: One sheet of notes, pencils, scratch paper, calculator. No time limit. There are two parts to this exam. The rst part consists of multiple choice questions. Each multiple choice problem is worth 4 points. The second part consists of worked problems. For these problems you will need to show your work to receive credit. Each of the worked problems is worth 9 points. Do not write on this exam! Answers to the multiple choice problems should be recorded on your bubble sheet. Your work and answers to the worked problems should be done on your Worked Problem Answer Sheet. For multiple choice questions with numerical answers, the choices represent the answer rounded to three signicant gures To receive full credit on the worked problems section, please show all work clearly and write neatly. If you wish to get partial credit on problems with incorrect answers, be sure to solve all questions algebraically rst, then plug in numbers with units) to get the nal answer. Unless otherwise instructed, give all numerical answers to three signicant digits in SI units. For answers that rely on intermediate results, remember to keep extra digits in the intermediate results, otherwise your nal 3 signicant digits may be o - be especially careful when subtracting two similar numbers! Also, remember to check your work by making sure your results make sense and have correct units. You can also consider what happens when you set a variable to a value that gives you a known result and verify that your equation indeed gives you that result. Do not do work for one problem in space allotted for another problem. Multiple Choice 1. I measure the sound level in the cockpit of an airplane with a meter, and it reads 58.3 decibels.

If the game physics does buoyancy right, the lava has a density of 5700 kg/m 3, the stones have a density of 4840 kg/m 3, the stones are cubes with side length L with one surface perfectly horizontal, the acceleration due to gravity on this level is 43.7 m/s 2 and Mario has a mass of 70.6 kg, what is the minimum value for L that will keep Mario's feet from touching the lava? 18. When you stand next to the Hogwarts Express, and the train is not moving, its whistle has a frequency of 736 Hz. One day you miss the train, so you steal a ying car and try to catch up with it. After ying through 3

4 some clouds, you realize that you have overshot the train. The train is traveling toward you at a velocity of 251 meters per second relative to the ground, and you are ying at a velocity of 86 meters per second away from the train, hoping not to get run over by the train. As you are doing this, you hear the train whistle. What frequency do you hear it at? Assume that the speed of sound is 343 meters per second, and give your answer to three signicant digits. 19. A guitar string with a length of 1.14 meters has a second harmonic with a frequency of 404 Hz when the tension in the string is 190 Newtons. What should I change the tension in the string to be if I want the third harmonic of the string to have a frequency of 639 Hz? 20. A pump is pumping water from a lake up a hill to a spigot a height of 10.9 meters above the outlet of the pump. The pipe carrying the water has a radius of 28.9 cm at the outlet of the pump, and the pipe tapers such that it has a radius of 6.03 cm at the spigot. Water ows out of the spigot with a velocity of 7.31 meters per second. Given that atmospheric pressure is Pascals, the density of water is kg/m 3, and that the acceleration due to gravity is 9.8 m/s 2, what is the pressure in the tube at the outlet of the pump? 4

5 Solutions 17. The buoyant force must be equal to the weight of the stone plus Mario's weight when the stone is just barely submerged. Since the buoyant force is equal to the mass of the displaced water, this means that ρ lava L 3 g = ρ stone L 3 g + m Mario g 18. Solving for L we get Plugging in numbers we get L = mmario ρ lava ρ stone L = 0.435m f = f v ± v o v v s ) 1/3 Since the train is going toward the car and the car is going away from the train, when we choose the correct signs we get f = f v v o v v s Plugging in numbers we get f 343m/s 86m/s = 736Hz 343m/s 251m/s = Hz 19. The frequency of any given harmonic is So the rst frequency is given by and the second frequency is given by If I divide the two equations, I get Solving for T 2, I get Plugging in numbers we get f = v λ = T n µ 2L. f 1 = f 2 = T 1 2 µ 2L T 2 3 µ 2L. f 1 T1 2 = f 2 T 2 3. T 2 = T f 2 f 1 ) 2. ) T 2 = 190N = 211N. 20. If I call the outlet of the pump point a and the spigot point b, then Bernoulli's equation tells us that P a ρv2 a + ρgh a = P b ρv2 b + ρgh b. Solving this for P a we get P b = P a ρv2 a + ρgh a 1 2 ρv2 b ρgh b 5

6 or P a = P b ρ v 2 b v 2 a) + ρghb h a ). The pressure at the spigot is atmospheric pressure, and we are given v b, ρ, h b h a, and g. So all we are missing is v a. The continuity equation tells us that A a v a = A b v b. So v a = A b A a v b = rb r a ) 2 v b and P a = P b + 1 ) ) 4 rb 2 ρv2 b 1 + ρgh b h a ). r a Plugging numbers in we get P a = Pa + 1 kg m ) 2 2 m 3 1 s ) ) kg m 3 9.8m s m = Pa kg kg ms2 ms 2 Or P a = Pascals 6
