A professional, modern, and high-quality redesign of the educational textbook physics page on 'ВОЗДУХОПЛАВАНИЕ' (Aerostatics / Buoyancy in Air) based on the reference layout. Top section: detailed infographic of a cute brown bear floating under a large blue balloon with force vectors (Archimedes buoyant force FA pointing up, Gravity force Fтяж pointing down, surrounding air molecules/bees). Bottom section: a hot air balloon with people in the basket, showing upward lifting force Fпод = FA - Fтяж and gravitational force Fтяж. Clean modern educational vector illustration style, vibrant clear colors, crisp Russian educational text, formulas, and neatly organized infographic callouts, white clean page background, high resolution book layout.
