A 200 kg steel beam falls from a crane onto the ground 30 m below? What speed does it hit the ground with?

a

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.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

a is the best answer your welcome
