The answer is B y = 5x - 14
Answer: (a) Magnetic flux before rotation is 7.2 × 10^-8 Wb and magnetic flux after rotation is 0
(b) The average emf induced in the coil is 3.6×10^-4 V
Step-by-step explanation:
Here is the complete question:
In a physics laboratory experiment, a coil with 200 turns en-closing an area of 12 cm2 is rotated in 0.040 s 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 6.0×10^−5T. (a) What is the total magnetic flux through the coil before it is rotated? After it is rotated? (b) What is the average emf induced in the coil?

Answer:
you would divide 28 by 8 and get 3.5. so around 3:30 per song
Step-by-step explanation:
First one is 672 the second one is 1008 the third one is 1344 the last one is 1512
The answer is 90 degrees. SO it would be B
