What is the efficiency of a lightbulb that puts out 300 J of light for every 1,500 J of electricity?

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

that would be because of both gravity and friction. so     c

the rearrangement of particles in a physical change. hope this
