Acircular coil of wire of radius 8 cm and 19 turns is placed with its plane perpendicular to a 5.6 t magnetic field, produced by an electromagnet. the current to the electromagnet is then switched off, causing the magnetic field to collapse to zero in a time of 744 ms. what is the emf generated in the coil while the magnetic field is collapsing, in units of volts?

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
