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 = 8 and ℓ = 0.7. find the rate of change dv/dv.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
