choose the true biconditional statement that can be formed from the
conditional statement "if the area of a square is 25 square meters, then the
side length of the square is 5 meters" and its converse.

a. the side length of a square is 5 meters if and only if the area of
the square is not 25 square meters.

b. a biconditional cannot be formed because the statement and its
converse are not logically equivalent.

c. the area of a square is 25 square meters if and only if the side
length of the square is 5 meters.

d. if the side length of a square is not 5 meters, then the area of the
square is not 25 square meters.

answer:

e - b - d - a - c

explanation:

the magnitude of the emf induced in the loop of wire is given by faraday-newmann-lenz

(1)

where

is the variation of magnetic flux

is the time interval

rewriting the flux as product between magnetic field strength (b) and area enclosed by the coil (a):

and since the area of the coil does not change, the variation of flux can be rewritten as

so (1) becomes

which means that the induced emf is proportional to the rate of change of the magnetic field, . so we just need to calculate this quantity for each scenario, and rank them from greatest to latest.

we have:

a)

b)

c)

d)

e)

so, from greatest to least magnitude, we have:

e - b - d - a - c
