Задача 31101.

The current intensity in a conductor is varied from time t1 = C c to t2 = 7, according to the law I = t ^ 2 A + B, where A = 0.1 A / s ^ 2, 2 = A. Determine the charge passed on conductor.

Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
