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=2 and l=0.7.

find the rate of change dvdv.

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000
