a. A sculptor has asked you to help electroplate gold onto a brass statue. You know that the charge carriers in the ionic solution are singly ionized gold ions, and you've calculated that you must deposit 0.50 g of gold to reach the necessary thickness. How much current do you need, in mA, to plate the statue in 4.0 hours? b. A metallic wire has a diameter of 4.12mm. When the current in the wire is 8.00A, the drift velocity...

HI Review Constants Part B A circular ring with area 4.45 crnº is carrying a current of 12.5 A. The ring, initially at rest, is immersed in a region of uniform magnetic field given by B = (1.25 x 10-2 T)(12î +39 – 4). The ring is positioned initially such that its magnetic moment orientation is given by ;=(-0.81 +0.61), where he is the positive) magnitude of the magnetic moment. Determine the components of initial magnetic torque of the current-carrying...
