A wire initially has length L_0 and resistance 5.00 Omega. The resistance is to be increased to 45.0 Omega by stretching the wire. Assuming that the resistivity and density of the material are unaffected by the stretching, find the ratio of the new length to L_(0) .

A conducting rod AB of length l is rotated about point O with an angular velocity velocity omega in a uniform magnetic field (B_0) directed perpendicular into the plane of rotation as shown in the figure. The value of V_B - V_A is
