By Faraday's Law, if a conducting wire of length ℓ meters moves at velocity v m/s perpendicular to a magnetic field of strength B (in teslas), a voltage of size V = −Bℓv is induced in the wire.

By Faraday's Law, if a conducting wire of length ℓ meters moves at velocity v m/s perpendicular to a magnetic field of strength B (in teslas), a voltage of size V = −Bℓv is induced in the wire. Assume that B = 5 and ℓ = 0.9. Find the rate of change dV/dv.Find the rate of change of V with respect to time t if v(t) = 9t + 9.
