Problem 4 (10 points) Helmholtz resonator If you blow across the neck of a glass bottle, you can, depending on your experimental skill, coax a relatively clear tone from the bottle. This arises from oscillations of the air in the bottle neck. The frequency f of this oscillation depends on the volume of air below the bottle neck in the wide part of the bottle, and for not-too-small volumes is given approximately by Here cS denotes the speed of sound, A the cross-sectional area of the bottle neck, and V the volume of air in the bottle excluding the neck. Furthermore, ̃L corresponds to the corrected length of the bottle neck, which accounts for the fact that the air pressure at the upper edge of the bottle neck does not immediately fall to the external air pressure. You may assume that ̃L $\approx L + π$ 4 d, where L denotes the length of the bottle neck and d its inner diameter. In this experiment you are to investigate the frequency of the resulting tone as a function of the air volume present in the bottle. For this you need a cylindrical glass bottle with a neck that is as straight as possible (e.g. from a soft drink or wine), a kitchen scale or a measuring jug that is as accurate as possible, water, and a ruler. To determine the frequency of the resulting tone you can, for example, use the “Audio Autocorrelation” function of the phyphox app, which displays the frequency of a tone directly. The given formula allows the speed of sound to be calculated for each value pair of frequency and volume. However, in order to detect systematic deviations better and to keep individual values with large errors from carrying too much weight, it is advisable to linearise the given relationship between the frequency f and the volume V and to evaluate it graphically. 4.a) Rearrange the given formulas so that a linear relationship arises between a function of the frequency f and a function of the volume V, which yields a straight line when plotted graphically. Explain how you can determine the speed of sound cS with the help of the straight line. 4.b) Take a series of measurements and produce a suitable graph from them. Use this to determine the speed of sound in air at room temperature. In doing so, describe how you proceeded, and estimate the uncertainty of your result. Finally, compare the speed of sound you determined with a literature value. Junior problem (10 points) A good idea The first and often most important step in solving problems is a good idea. The following two problems can be solved very quickly with the right idea in each case. 5.a) The circuit shown consists of identical voltage sources, each with a voltage of U = 1.5 V, and identical resistors with resistance value R = 100 $Ω$ .

Determine the current I flowing through the lower left resistor. 5.b) Two athletes ride their tandem in serpentine lines. The to-scale figure shows the track of the rear wheel of the tandem. The distance between the centres of the rear and front wheels is 2.0 m.

Construct in the figure the track of the front tyre of the tandem, given that the tyres roll without slipping.

Students If you are a student, the IPhO and the PhysicsOlympiad in Germany offer you diverse opportunities to engage intensively with physics questions, to experience physics as an exciting scientific discipline, to test your own limits, and not least to meet interesting people. For the competition rounds there are learning materials and training problems that help you deepen your knowledge and problem-solving skills. At the seminars you meet many other young people enthusiastic about physics. Taking part is therefore worthwhile in any case, regardless of whether you make it to the higher rounds. What matters is to be there. Successfully completing the first round is already a special achievement and a real distinction. So, take heart! Teachers As a teacher, you can offer a challenge in physics to particularly capable or interested students with the problems of the PhysicsOlympiad and encourage them to engage more deeply with physics topics. The PhysicsOlympiad can thus serve as an instrument of individual support. The problems of the 1st round in particular are suitable not only for the best in a class.

With a wide range of offerings, the PhysicsOlympiad aims to reach interested young people broadly and to inspire them lastingly for the natural sciences. To this end there are support offerings such as the Orpheus seminars and the accompanying materials for the 1st round, with which we want to support you in introducing topics of the PhysicsOlympiad. So please encourage your students to take part; for only those who do not take part can lose. Schools By encouraging participation in competitions, schools can sharpen their profile and use them, in the sense of enrichment, as a complement to school offerings. Competitions provide diverse, differentiated learning environments for participating students. In the area of STEM subjects, the Olympiads, at least in the later rounds, represent a competition aimed at particularly motivated and high-performing young people. Nevertheless, participation is not only worthwhile even in the entry rounds, but can also contribute to a lasting enthusiasm for STEM topics. Offerings such as the Orpheus seminars allow the support of a large number of participants. In many federal states, participation can incidentally be recognised as a special academic achievement or subject/seminar paper of your students for the Abitur. Interested in more than physics? The IPhO is one of the six nationwide scientific student competitions organised by the IPN – the ScienceOlympiads. In addition to the selection competitions for the international Olympiads in Biology (IBO), Chemistry (IChO) and Physics (IPhO), they also include the International JuniorScience Olympiad (IJSO), the European Olympiad of Experimental Science (EOES), and the Federal Environmental Competition (BUW). Together they address students from the beginning of secondary school until after the end of school, and, through close networking, offer the possibility of lasting support of scientific abilities and interests. Further information at: www.scienceolympiaden.de Many good reasons to take part in the PhysicsOlympiad Dear students, dear parents and teachers, the world is changing. And there is so much to do. We must make progress on climate protection, use digitalisation wisely, achieve advances in medicine. I am sure: we will manage it. And why am I sure: because we have science and research. They create the foundations for new things, for innovations, for answers to the questions of our time, so that we can lead a good, self-determined and healthy life. What matters is that we activate all our creative and intellectual reserves for this, and above all also inspire young people early on for the natural sciences, for maths and computer science.

Problema 4 (10 punti) Risonatore di Helmholtz Se si soffia attraverso il collo di una bottiglia di vetro, si può, a seconda della vostra abilità sperimentale, coax un relativamente

Tono chiaro dalla bottiglia. Questo deriva da oscillazioni dell’aria nel collo della bottiglia. La frequenza f di questa oscillazione dipende dal volume di aria sotto il collo della bottiglia nella parte larga della bottiglia, e per i volumi non troppo piccoli è given approximately by Qui cS indica la velocità del suono, A l’area cross-sectional del collo della bottiglia, e V il volume di aria nella bottiglia escludendo il collo. Inoltre, ‘L corrisponde alla corretta lunghezza del bottle neck, che rappresenta il fatto che il bottle neck è stato che la pressione dell’aria all’orlo superiore del collo della bottiglia non scenda immediatamente alla pressione dell’aria esterna. Potresti pensare che che ̃L $\approx L + π$ 4 d, dove L indica la lunghezza del collo della bottiglia e il suo diametro interno. In questo esperimento, si deve indagare la frequenza del tono risultante in funzione del volume d’aria presente nel flacone. Per questo ti serve una bottiglia di vetro cilindrica con un collo che sia il più dritto possibile (es. da una bevanda O vino), una scala di cucina o un vassoio di misurazione che sia il più accurato possibile, acqua, e un regolare. Per determinare il Frequency of the resulting tone (frequency of the resulting tone) puoi, per esempio, utilizzare la funzione “Audio autocorrelation” dell’app phyphox, che visualizza il Frequenza di un tono direttamente. La formula data consente di calcolare la velocità del suono per ogni valore di frequenza e volume. Tuttavia, per rilevare meglio le deviazioni sistematiche e mantenere i valori individuali con grandi errori dal portare troppo peso, è consigliabile lineare la relazione data tra la frequenza f e il volume V e valutarla graficamente.

(a) Riorganizzare le formule così che si verifichi una relazione lineare tra una funzione della frequenza f e una funzione del volume V, che produce una linea retta quando tracciata graficamente. Spiegate come determinare la velocità del suono cs con l’aiuto della linea dritta. 4.b) Prendi una serie di misure e produce un grafico adatto da esse. Usate questo per determinare la velocità del suono in aria a temperatura ambiente. In tal modo, descrivi come hai proceduto, e stima l’incertezza del tuo risultato. Finalmente, compare la velocità di suono determinata con un valore letterario. Problema minore (10 punti)
