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?

6/30 = 1/5
This means that 1/5 of the students in a class will be left-handed.
27*5 = 135
27/135 = 1/5
The correct answer is 135 students.

Step-by-step explanation:
(4,7) is just 4 and 7 but [4,7] is all the points between 4 and 7. I am pretty sure this is correct, but i could be wrong. Hope this helped!
Answer:
i think the answer would be 1/6 hope this helps!
