How does Newton's 3rd Law of Motion account for the lift of an airplane wing? A) The shape of the wing lowers gravity on the plane. B) The shape of the wing increases the density of the air, so it is heavier than the wing.

To use Faraday's law for this problem, you will need to construct a suitable loop, around which you will integrate the electric field. In which plane should the loop lie to get a nonzero electric field line integral and a nonzero magnetic flux? a.
