Answer:

According to Farady law of electromagnetic induction. "Rate of chabge of magbetic flux is equak to induced emf."

So

induced Emf = magnetic flux ÷ time

Answer:

10V

Explanation:

Induced emf = d(magnetic flux)/dt

= d(3t^2 - 2t+5)/dt

= 3*2t - 2*1+0

= 6t -2

At t =2s

Induced emf = 6*2 - 2 =12-2 =10V
