Cho dòng điện thẳng dài vô hạn có cường độ không đổi I 1 =
5A chạy qua và dòng điện I 2 = 10A chạy trong khung dây hình chữ
nhật theo chiều ABCD có cạnh bằng a = 30cm và b = 50cm . Cạnh AB
song song với dòng điện, cách dòng điện một khoảng R . Hãy xác định
từ lực tác dụng lên từng cạnh của khung. Cho uy = 1. uy 0 = 4.pi..10 -7 H/m.

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
