A straight moveable conducting bar (red color) completes the 4th side of a rectangular circuit as show below. The circuit loop has dimensions a = 23 cm by b = 88 cm at a specific instant in time. Inside the circuit loop a uniform magnetic field B_out of magnitude 47 mT is directed outward and perpendicular to the plane of the circuit. Connected in the circuit is a light bulb having resistance= 25 ? . When the bar moves with a constant speed v, it causes the lightbulb to expend energy at a constant rate of 219 ?W. Determine the speed (m/s) of the bar. Give answer in m/s and to two places to the right of the decimal.
