На горизонтальном дне бассейна , имеющего глубину h=2 метра, лежит плоское зеркало mn, луч света , переломившись на поверхности воды, отражается от зеркала и выходит в воздух. Расстояние от места вхождения луча в воду до места выхода отраженного луча из воды l=1,5м. Найти угол падения луча а . Показатель преломления воды n=1,33

He viscosities of several liquids are being compared. all the liquids are poured down a slope with equal path lengths. the liquid with the highest viscosity will

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
