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.

The air molecules bump into eachother and this is how sound, energy, is transmitted in waves. When the air is more dense the sound is able to travel further as energy is conserved because there are more molecules to interact with.Sound waves are a form of energy that involves millions of kinetic interactions in a medium. As energy increases so does the frequency and pitch.Gbaby222 Â· 8 years ago.hen the air is more dense the sound is able to travel further as energy is conserved because there are more molecules to interact with.
