In a physics laboratory experiment, a coil with 170 turns enclosing an area of 14 cm2cm2 is rotated in a time interval of 0.050 ss from a position where its plane is perpendicular to the earth's magnetic field to a position where its plane is parallel to the field. The earth's magnetic field at the lab location is 7.0×10−5 TT.   What is the average emf induced in the coil?
