A10-cm-long wire is pulled along a u-shaped conducting rail in a perpendicular magnetic field. the total resistance of the wire and rail is 0.33 ω . pulling the wire with a force of 1.3 n causes 4.5 wof power to be dissipated in the circuit. what is the speed of the wire when pulled with 1.3 n ? express your answer using two significant figures.
what is the strength of the magnetic field? express your answer using two significant figures.
