I think the correct answer from the choices listed above is option D. One advantage of using electromagnets in devices would be that electromagnets can <span>easily be turned on and off. Hope this answers the question. Have a nice day.</span>
Answer:
I'm not super sure what your asking for. But these look like elements of communication from a speech or communications class.
--------------message-------->
O O
\ | / ------ channel ------ \ | /
/\ /\

- Body language can assist (or not) in sending the message.
Have in mind: Energy is always conserved and, (...) be transferred between objects or systems, from one form to another.
Hence, the true relation is C, when a system gains kinetic energy, it loses potential energy.
Think about this,
K + P = constant
If K increases, then P need to decreases to holds the above relation.
