Which does NOT demonstrate a change caused by Jenna applying energy to the the book?

I'm not sure what your asking buddy.. but i know that you can weld two peices of steel by pure force and pressure.

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.

D) the event horizon, a large planet and the chute located between the two.
