Какова напряженность поля в точке, удаленной от электрического заряда на 12см, если на расстоянии 9 см она равна 1,6•103Н/Кл? в метсе с дано и решением
Закон сложения скоростей, соизмеримых со скоростью света, входит в число основных выводов специальной теории относительности (СТО) , которые приводятся и в школьных учебниках. Вот формула для вычисления: v = (v1 + v2)/ (1 + v1*v2/c (кв) ). Вычислим: учитывая что v1 = v2 = v; : v (отн. ) = (v+ v)/ (1 + v*v./с*с) = 2vс ( кв) /(с (кв) + м (кв) ) = 2*0,8с*с/ (с (кв) + 0,64с (кв) ) = 2*0,8/(1 +0,64) = 1,6/ 1,64 = 0,98 с; Это и можно считать ответом v = 0,98c. Ни при каких скоростях относительная скорость не может превышать скорости света с = 3*10(в 8 ст) м/с. ответ можно выразить и в м/с . v = 0,98*3*10(в 8 ст) м/с = 294 000 000 м/с = 294 000 км/с.
Match the 2 parts of the sentences from paragraph of text 1.
Moldagulova Aliya Nurmukhambetovna was a sniper of the 54th sniper brigade. She was born on October 25, 1925 in a small village in Aktobe province. She was Kazakh. She lost her parents and lived in Almaty with her uncle. Since 1935, Aliya lived in orphanage No. 46 in Leningrad.
At the beginning of the war, she moved from Leningrad. She graduated from the 7th grade of high school in 1942. She studied at the Rybnisk Aviation Technical School. In 1943, she graduated from the school of snipers in Moscow. She was in the army since October 1943. Aliya Moldagulova was the brave and best sniper in the brigade. Aliya was one of the bravest soldiers of the Second World War. She was not afraid of enemies and made many efforts to win.
