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=7 and l=0.5. Find the rate of change dV/dv. (Use decimal notation. Give your answer to three decimal places.) dV/dv = ? Find the rate of change of V with respect to time t if v=9t+9. (Use decimal notation. Give your answer to three decimal places.) dV/dt = P.S: I got dV/dv= -3.5 that is right but for dV/dt= i got -22.5 but it keeps on saying it's wrong
