F= kx solve for k a) f/x b) x/f c) f + x d) f - x

A) f/x

kx=f (flipped)

Divide both of the sides by x.

That removes the x from k on the left.

k=f/x

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )
