A coil with 275 turns and a cross-sectional area of 0.750m2 experiences a magnetic field whose strength increases by +0.900 T in 1.25 s. The plane of the coil is perpendicular to the plane of the magnetic field. What is the induced emf in the coil?

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
