Документ Dynamics of oscillation processes in siphon U-tubes(Харківський національний університет імені В. Н. Каразіна, 2015) Tkachenko, O. Y.; Kazachkov, A. R.; Lykah, V. A.; Minakova, K. A.; Syrkin, E. S.The dynamics of oscillation processes in a siphon U-tube is studied for the system of connected vessels fi lled with homogeneous liquid. The equations and phase paths describing the motion of non-viscous liquid and fountain eff ects are given, oscillation frequencies are considered. Oscillations are nonlinear in general case, but they turn into linear by setting special parameters of the system. Phase portraits are obtained and their dependences on parameters of the system are analyzed for the linear and non-linear cases. It is shown that the behavior of the deep and shallow water in such a system could be discussed using analogy with the propagation of elastic waves in condensed matter. Some interesting analogies between a siphon U-tube and hydrodynamic, mechanical, electromagnetic phenomena, wave motion are also analyzed.Документ Electricity on Paper(Serednyak T. K., 2019) Kolomiets, S.; Andreev, A. N.; Andreeva, O. N.; Minakova, K. A.The paper proposes a practical cycle of classes on electricity at school. The main goal of these classes is to form students' interest in physics and electronics, as well as acquaint them with the basics of building electrical circuits and their main components.Документ Explanation of the Basic Models of Color Mix in the Classroom for Physics(Serednyak T. K., 2019) Andreeva, O. N.; Andreev, A. N.; Minakova, K. A.The article describes the demonstrations that allow you to show the basic color mixing models, and presents the developed simple colorimeter.Документ Liquid Nonlinear Oscillations in the U-Tube System(NTU "KhPI", 2016) Kazachkov, A. R.; Lykah, V. A.; Minakova, K. A.; Syrkin, E. S.; Tkachenko, O. Y.Dynamics of oscillation processes in a siphon U-tube is studied for the system of connected vessels filled with homogeneous liquid. The equations and phase paths describing the motion of viscous and non-viscous liquids are given, oscillation frequencies are considered. Oscillations are nonlinear in general case, but they turn into linear by setting specific parameter values of the system. Phase portraits are obtained and their dependences on parameters of the system are analyzedfor both linear and non-linear cases.Документ Study of the Magnetic Field Current-Carrying Conductor of Various Geometric Shapes(Serednyak T. K., 2019) Andreev, A. N.; Andreeva, O. N.; Minakova, K. A.The article presents a detailed description of an available compact measuring complex for studying the magnetic field of conductors with different currents based on the ATmega 328 microcontroller. The conductor is fixed on the tablet (horizontal surface with a hole system containing a digital magnetic field sensor) with a thermoplastic adhesive. This makes it possible to investigate the magnetic field of not only closed circuits with a current of various geometric shapes, but also individual sections of the conductor. The use of a microcontroller allows to reduce the error of the obtained experimental results by automated repeated repetition of measurements and their subsequent averaging. With the help of the developed complex, the Biot-Savart-Laplace law and the principle of superposition of the magnetic field for circular currents of different diameters, with different currents flowing through the circuit were verified using a graphical method. It is established that the error of measurements of current strength and magnetic field induction does not exceed 10%.
