Solution to task 379 from Chertov´s for extramural stud

379. The current in the circuit changes according to the law I = I0sinωt. Determine the amount of heat that will be released in a conductor with a resistance of R = 10 Ohm in a time equal to a quarter of the period (from t1 = 0 to t2 = T / 4, where T = 10c).
