By definition, electromagnetic induction is the term that is generally used to describe the method of generating a potential difference across a conductor through a changing magnetic field. In addition, the induce current would be minimised if the loop is placed parallel to the magnetic field itself. Therefore, C.
im not sure what ur asking. but c is a line segment
5y+2 i think because those are parallel lines:)
Y=13
(when you have fractions like the one in this problem, you get rid of them by multiplying both sides by the denominator.)
