Problem 3:Joe has rolled a long electrical extension cord into a coil of radiusrc=14cmc=14cmwithNc=15c=15loops. The coil of extension cord is initially lying horizontally (flat) on the floor of Joe's garage. Joe picks up the coil and rotates it9090 counterclockwise intr=0.85s so that the coil is now vertically oriented (see the figure).

$2 33% Part (a) If the Earth's magnetic field has strength 0.50 gauss and makes an angle of 20.0 degrees with the garage floor, calculate the change in the magnetic flux Ag, in webers, through one of the loops of the coil during the rotation. Treat the initial flux as having a positive sign. @ Degrees O Radians Submit Hint Adgp ={0.0034 tanh) Hints: 0% deduction per hint. Hints remaining: 4 {0l macromer | e cmar I give up!
