465. A frame made of wire with resistance R = 0.04 Ohm rotates uniformly in a uniform magnetic field (B = 0.6 T). The axis of rotation lies in the plane of the frame and is perpendicular to the lines of induction. Frame area S = 200 cm2. Determine the charge Q that will flow through the frame when the angle changes between the normal to the frame and the induction lines: 1) from 0 to 45 °; 2) from 45 to 90 °.
