A square coil, enclosing an area with sides 2.7 cm long, is wrapped with 2,461 turns of wire. A uniform magnetic field perpendicular to its plane is turned on and increases to 0.39 T during an interval of 0.8 s. What average voltage is induced in the coil? Express the answer with two decimal places.
what is the cost of the electric energy equivalent to the energy in a Big Mac? (the cost of a Big Mac is $3.57)
An object with a charge of 0.880 µC is placed at the center of a regular icosahedron with 20 equivalent surfaces. What is the electric flux through one surface of the icosahedron?
