P=I*U
I=P/U=100/200=0,5 A
Закон Ома: I=U/R
I- сила тока
U- напряжение участка
R- сопротивление участка

помогите ответить на вопросы! Carl Jung (1875-1961) was a Swiss psychiatrist who had a lasting influence on psychology and society. He studied medicine at the University of Basel from 1894 to 1900, specialising in psychiatric medicine. Jung developed ideas about personality types which still interest and influence people today. He identified two personality types which he called introverts and extroverts. According to Jung, extroverts find meaning outside themselves, in the surrounding world. However, introverts are introspective. They look into themselves and find meaning in themselves. Extroverts seem to like other people. It is easy for them to form close relationships. They enjoy the excitement of crowds. They tend to be assertive, self-confident, and are often leaders in groups. They are energetic and lead busy lives. In general, they are talkative, adventurous and sociable. Introverts, on the other hand, feel comfortable alone. They avoid large crowds. They are relaxed, thoughtful and reflect before they act. They are often quiet, cautious and have good powers of concentration. They often have creative ideas. Jung's influence on our society and culture has been enormous. Two well-known tests (Myers-Briggs and David Keirsey) are based on his theory of personality types. His ideas have influenced writers as well as film-makers like Fellini and Kubrick. Jung's ideas have even influenced video games and rock music groups. There is still great interest in his theories on the interpretations of dreams. ​

В ТЭБ США и стран Западной Европы в первой половине 20века удельный вес нефти неуклонно повышался. Несколько иная картина наблюдалась в ТЭБ республик бывшего СССР, где уголь долго не сдавал своих позиций. В чем состояла причина такого положения?
