B. Magnets convert electric energy into mechanical energy

C. Magnets detect the presence of electric currents in nature.

D. Moving a magnet in a coil of wire generates an electric current

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

if they have a finite resultant

1 the 4 is sig
