a$)$ A square wire loop with $2$ m sides is perpendicular to a uniform magnetic field. The field magnitude is given by B $-5-$ c$*,$ with B in Tesla, and t in seconds.

Find:

$1.$ The magnitude of the induced emf in the square loop at t $=3$s$.(.../4$ pts$)$

$2.$ The induced current in the loop at t $=3$s$,$ knowing that the resistance of$$the$$loop$$is$2$Q
