The figure shows a wire that has been bent into a circular arc of radius r = 26.0 cm, centered at O. A straight wire OP can be rotated about O and makes sliding contact with the arc at P. Another straight wire OQ completes the conducting loop. The three wires have cross-sectional area A = 1.32 mm² and resistivity p= 4.05 x 108.m, and the apparatus lies in a uniform magnetic field of magnitude B = 0.160 T directed out of the figure. Wire OP begins from rest at angle 0 = 0 and has constant angular acceleration of 15.0 rad/s2. As functions of (in rad), find (a) the loop's resistance and (b) the magnetic flux through the loop. (c) For what is the induced current maximum and (d) what is that maximum? (a) (b) (c) i Units ľ (d) i Units
