Water is a really good conductor of sound so I would have to say that it would be to send the message underwater because a more dense medium produces a louder sound
A) An electrical resistor
Hope that helps, Good luck! (:
Answer:
We can also prove the conservation of mechanical energy of a freely falling body by the work-energy theorem, which states that change in kinetic energy of a body is equal to work done on it. i.e. W=ΔK. And ΔE=ΔK+ΔU. Hence the mechanical energy of the body is conserved
