Грузик, подвешенный на нити , вращается в горизонтальной плоскости с постоянной частотой 0.5 об/с . определите расстояние от точки подвеса до плоскости , в которой происходит вращениерешите, , сами, не копируйте чужие ответы.)

Из подобия соответствующих треугольников подвеса и сил следует tgα = ma/mg = r/h значит, искомая h равна: h = rg/a здесь m - масса грузика g=9,8 м с⁻² - ускорение свободного падения a  - центростремительное ускорение a = ω²r ω - круговая частота r - радиус траектории грузика h - расстояние от подвеса до плоскости вращения ω = 2пf f = 0.5 гц - частота вращения грузика откуда, после элементарных преобразований получается: h = g/(4·п²·f²) = 9.8/(4*3.14²0.5²) = 1 м

Привет очень сложно бяло моему перекладачу но справился )))хахаха

I live at home. I really like my house. it is small, but I am not small either. When you enter the house, you see a small kitchen. in the kitchen we cook and eat. I spend a lot of time in the kitchen, because I like to eat. The next room is the entrance hall. in the hallway there is a large closet over the entire wall. there are no windows. through the hallway we go into other rooms. our room is very large. there is a large sofa. the hall is very bright because there are many windows. there are many different colors in the room. The room of my parents and sister is also large. a large TV hangs to the room, it hangs above a large soft bed and there is a bedside table to the right of the bed. and in the second half of the room is my sister’s sofa. my room is the smallest. I even like it. To my room there is an extendable sofa, a table and a TV. there is a yard around the house. My mother loves to grow flowers. we have a bathhouse in our yard. and we also have a dog that lives in a booth that dad built. We have a garage for my father’s car and tools. We also store our things there.
