If GFR is over 90, the kidneys are healthy and functioning normally. A kidney score of 60-89 means the person should be monitored, and if GFR scores falls to less than 60 for a three-month period, that is an indicator of chronic kidney disease.
Posted on. (Answer #2). Sound is a form of mechanical energy because the source of sound is vibration. Mechanical energy consists of gravitational potential energy and kinetic energy. Vibrating particles have kinetic energy which is a form of mechanical energy.osted on. (Answer #2). Sound is a form of mechanical energy because the source of sound is vibration.

Simple Version: The energy in a sound wave is mechanical, being both kinetic and potential energy associated with the air. Explained: Just as in a vibrating spring, the â¦ medium (air) has mass and moves and so moving mass is kinetic energy.irst of all, sound waves are mechanical energy. Secondly, anything that makes noise because it is moving would be an example of mechanical energy turning into sound energy; â¦ like a car going down the road, a gun shot, or somebody slapping their palm against their forehead.
