УМОЛЯЮ!
С какой силой действует магнитное поле с индукцией 19 мТл на проводник, в котором сила тока 39 А, если длина активной части проводника 11 см? Линии магнитной индукции поля и направление тока взаимно перпендикулярны.
(Ответ округли до тысячных.)

Автор ответа: lizashaxnazarova

Формула:
Fа=В*I(сила тока)*l(длина)*sinA
19мТл=19:1000=0,019 Тл
11см=0,11м
Т.к. они перпендикулярны, то угол равен 90 градусам, а синус этого угла равен 1.
F=0,019*0,11*39*1=0,08151
0,08151~0,082

lizashaxnazarova: Вроде так, ответ:0,082

1. Marie Curie was born in Warsaw on 7 November, 1867. Her father was a teacher of science and mathematics in a school in the town, and from him little Maria Sklodowska - which was her Polish name - learned her first lessons in science. Maria's wish was to study at the Sorbonne in Paris, and after many years of waiting she finally left her native land in 1891.

2. In Paris Maria began a course of hard study and simple living. She determined to work for two Master's degrees - one in Physics, the other in Mathematics. This she had to work twice as hard as the ordinary student. Yet she had scarcely enough money to live on. She lived in the poorest quarter of Paris. Night after night, after her hard day's work at the University, she got to her poorly furnished room and worked at her books steadily for hours, Sometimes she had no more than a bag of cherries. Though she was often weak and ill, she worked in this way for four years. She had chosen her course and nothing could turn her from it.

3. Among the many scientists Maria met and worked with in Paris was Pierre Curie. Pierre Curie, born in 1859 in Paris, was the son of a doctor, and from early childhood he had been fascinated by science.

At sixteen he was a Bachelor of Science, and he took his Master's degree in Physics when he was eighteen: When helmet Maria Sklodowska he was thirty-five years old and was famous throughout Europe for his discoveries in magnetism. But in spite of the honour he had brought to France by his discoveries, the, French Government could only give him a very little salary as a reward, and the University of Paris refused him a laboratory of his own for his researches.
