D. Freezing water and burning coal
Explanation:
Explanation:
Yes, the law of conservation of energy still applies even if there is waste energy.
The waste energy are the transformation products of energy from one form to another.
According to the law of conservation of energy "energy is neither created nor destroyed by transformed from one form to another in a system".
But of then times, energy is lost as heat or sound within a system.
- If we take into account these waste energy, we can see that energy is indeed conserved.
- The sum total of the energy generated and those produced will be the same if we factor in other forms in which the energy has been transformed into.
Answer: Longitudinal Waves
Explanation: The particles of the medium pass parallel to the course that the heart beat moves. This sort of wave is a longitudinal wave. Longitudinal waves are usually characterised through particle motion being parallel to wave movement. A valid wave traveling thru air is a classic example of a longitudinal wave.
