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
